Item 1.   Business
          --------

          The Registrant is and for many years has been engaged in the
business of publishing and distributing advanced scientific and 
technical material.  The Registrant publishes and distributes books and
journals and creates and maintains databases for which it receives 
royalties from unrelated organizations providing access to such materials 
throughout the world under the imprints of Plenum Press, Consultants 
Bureau, DaCapo Press, IFI/Plenum Data, J.S. Canner & Company, and Human 
Sciences Press. The Registrant and its subsidiaries maintain offices in 
New York, New York; Wilmington, Delaware; Boston, Massachusetts; Wilmington, 
North Carolina; London, England; and Moscow, Russia; and warehouse 
facilities in Edison, New Jersey.
         The Registrant's principal markets are public and private 
libraries, technically oriented corporations, research organizations and 
individual scientists, engineers, research workers, other professionals 
and graduate students throughout the world.  Except as to the sale of 
reprints and trade books, the Registrant does not generally sell to book 
stores.  The Registrant's principal methods of marketing are by direct mail
and by advertising in scientific publications, including its own journals.
The Registrant makes a wide distribution of its catalogs of published 
material, as well as plans for new publications.  In certain foreign 
markets, the Registrant utilizes the services of independent distributors 
and agents.
          The Registrant generally secures copyrights on its publications 
in its own name or in the name of its subsidiaries. In some cases, pursuant 
to written agreement, the copyright is secured in the name of the author 
of the publication or a learned society or other organization.  Copyrights 
on translations of foreign journals are limited to English language 
translations and do not cover the original foreign language works.  Those 
translations of Russian journals as to which the Registrant is the
distributor but not the publisher are copyrighted in the name of the
publisher.  Most publications printed by the Registrant's DaCapo Press 
subsidiary are reprints of works in the public domain which are not subject 
to copyright protection or are works published by others who have sold to 
the Registrant certain rights for publication, either for a fixed payment 
or under a royalty agreement.
          The Registrant does not perform any printing operations.  It uses 
outside printing and binding services, with much of the material being 
prepared by the Registrant for printing.  Preparations by the Registrant 
include editing, creation of a suitable design and typesetting.
          The following table sets forth the total revenues contributed 
by each class of similar products and services, and the income (loss) 
generated from securities owned by the Registrant.

Subscription Journals
- ---------------------

          During 1993, the Registrant published a total of 243
journals, of which 97 were translations of Russian language
scientific journals which represented a substantial portion of
the Registrant's subscription income.  The Russian journals are
in the fields of physical sciences, mathematics, engineering and
life sciences.  In December 1993, the Registrant entered into a
Journal Production and Distribution Agreement (the "Distribution
Agreement") with the Russian Academy of Sciences (the "Academy")
and other interested parties pursuant to which the litigation
then pending, relating to the translation of Russian scientific
journals, was ended, and Registrant's role as publisher and
distributor of certain of such journals was altered.  The Distri-
bution Agreement extends from 1994 through 2006.  In the lawsuit,
the Registrant had alleged a conspiracy by certain competing
entities to procure the breach of its translation contract with
the Copyright Agency of the former Soviet government ("VAAP") by
entering into agreements to obtain translation rights to certain
journals.
          Pursuant to the Distribution Agreement, in 1994 the
Registrant will distribute for MAIK Nauka ("MN"), an entity owned
in part by Pleiades Publishing, Inc. and the Academy, 21 Russian
scientific journals in English.  MN will become the exclusive
publisher of such journals.  Prior thereto, the Registrant had
translated, published and distributed these journals under a con-
tract with VAAP, and under contracts with the individual insti-
tutes publishing the journals, and had paid royalties based in
part upon the number of subscribers.  Under the Distribution
Agreement, the Registrant will continue to promote and distribute
these journals throughout the world, and will continue to deal
with and collect from subscribers to the journals, retaining a
portion of such revenues for performing its function.  In 1994,
the Registrant will retain 35% of the revenue, with the amount
gradually being reduced to 30% in 1999 and remaining at that
level for the balance of the term of the Distribution Agreement.
Revenue from such 21 journals in the 1993 journal year constituted 
6.7% of the Registrant's overall journal revenue and 16.2% of its
Russian journal revenue.  Nine of such journals were being published 
by both the Registrant and the predecessor of MN under conflicting 
contracts and were the subject of the above-mentioned litigation.
          Under the Distribution Agreement, in 1995 and 1996 MN
will undertake the publication of the English translations of 11
additional Russian journals, to be promoted and distributed by
the Registrant, representing a total of an additional 13.7% of
the Registrant's 1993 Russian journal revenue and 5.6% of its
total journal revenue.  Commencing in such years, MN  may elect
to publish the English translations of up to 23 additional
Russian journals, to be promoted and distributed by the Regis-
trant.  The total revenue to the Registrant from these 23 jour-
nals equals 29.2% of Registrant's 1993 Russian journal revenue
and 11.9% of its total journal revenue. As to each additional 
journal which is published by MN and distributed by the Registrant
under the Distribution Agreement, the Registrant will retain 35%
of the revenue in the initial year of distribution, with the amount
gradually being reduced to 30% over a six-year period.
          MN intends to cause the above-mentioned journals to be
translated and published in the former Soviet Union.  The Regis-
trant will continue its activities in translating, publishing and
distributing both the journals subject to the Distribution
Agreement until they are published by MN and the approximately 40
English Translation Russian Journals not subject to the Agreement.
These activities will be undertaken pursuant to the Registrant's 
existing English translation and publication contracts with the 
individual entities publishing the Russian language journals which 
generally extend through 2001.
          The translation journals published by MN will be
distributed by the Registrant under the MAIK Nauka/Interperiodica
imprint, and it will be indicated that they are distributed
worldwide by Plenum/Consultants Bureau.  Those translation
journals translated and published by the Registrant will continue
to be published under the Registrant's "Consultant's Bureau"
imprint.
          Management expects that in 1994 and thereafter, reve-
nues and net income from subscription journals will decrease as a
result of the Registrant's modified relationship to the transla-
tion journals covered by the Distribution Agreement, and also as
a result of the political and economic situation in Russia and in
the other republics of the former Soviet Union.
          The translation work required for the publication of
the Registrant's Russian language material is done primarily by
scientists and technical persons in the United States and else-
where who have other principal occupations.  The Registrant
maintains relationships with approximately 130 such persons, most
of whom have been rendering translation services to the Regis-
trant for several years.  The Registrant has been able to obtain
the required translators to enable it to meet its needs.  The
number of translators reflects a reduction from previous years
since the Registrant, under the Distribution Agreement, will be
translating fewer journals.
          In addition to the Russian Language Translation Jour-
nals, the Registrant published 96 journals in its English Lan-
guage Journal Program in 1993.  The journals are published under
the Registrant's "Plenum Press" imprint, and include titles in
chemistry, physics, mathematics, computer science, engineering,
biology, medicine, psychiatry, social sciences and law.  Each
journal is published under the direction of an editorial board
composed of professionals specializing in the fields of research
covered by the journal.
          The Registrant's subsidiary, Human Sciences Press,
Inc., publishes 50 journals, under the "Human Sciences Press"
imprint.  These journals are primarily in the health, behavioral
and social science fields.

Outside Journals
- ----------------

          In April 1993, an American learned society with which
the Registrant had a contract to produce English translations of
11 Russian language journals for publication by that society gave
notice that it would not exercise the option of renewing the
contract beyond the term ending with the 1993 volume year.  For
1993, the amount of revenue generated from the production of
these 11 journals was approximately $1,261,000; however, such
revenue will cease during 1994.
          The Registrant, through its Boston-based J.S. Canner &
Company, Inc. subsidiary, engages in the purchase and sale of
backissue periodicals to libraries, colleges, universities and
other users.

Books
- -----

          The Registrant's Plenum Press division publishes scientific, 
technical and medical books for use by scientists, engineers, research 
workers, other professionals and graduate students, and their 
supporting libraries, research laboratories and institutions.  During 
1993, the division published 288 new titles as part of this program, 
and had an active backlist of approximately 3,800 titles as of December 
31, 1993.  During 1992, 305 new titles were published.  Titles include 
comprehensive treatises, monographs and other advanced text-reference 
works, as well as proceedings of meetings reporting original scientific
research, works surveying the state of the art in various scientific 
fields and specialized bibliographies and data compilations.  In recent 
years, a number of books treating scientific topics of interest to the 
general reader have also been published.
          The Registrant's DaCapo Press, Inc. subsidiary publishes
reprints of books in music, dance, visual arts and the social
sciences.  These books are sold mainly to libraries and specialists
in these fields.  DaCapo also publishes a line of academic/trade 
paperbacks in the arts, biography and history.  During 1993, this 
subsidiary published 40 titles compared to 43 titles in the prior 
year.  As of December 31, 1993, this subsidiary had an active 
backlist of approximately 1,500 titles.
          The Registrant's Human Sciences Press, Inc. subsidiary
had an active backlist of approximately 400 titles as of December
31, 1993.  The Registrant has no immediate plans to publish new
titles under the Human Sciences imprint, but will continue to
publish the backlist under such imprint.  The Human Sciences
books are primarily in the health, behavioral and social science
fields, and are sold mainly to libraries and professionals in
these fields.

Database Products
- -----------------

          The Registrant's IFI/Plenum Data Corporation subsidiary
("IFI") is primarily involved in providing to major industrial
users on-line access to the IFI Comprehensive Data Base of
Patents, a computerized index file containing references to all
United States chemical and chemical related patents issued since
January 1950.  The Registrant's customers generally use terminals
at their own facilities to obtain the information through several
international database networks.  The file is further utilized by
IFI in its performance of patent searches for law firms and other
customers.  IFI produces other on-line databases for searching
chemical, general, electrical and mechanical United States
patents, and publishes in book format the Patent Intelligence and 
Technology Report and The Assignee Index, all of which are patent
information publications.  IFI also offers other online database
products including Mental Health Abstracts and Information
Science Abstracts.
          The Registrant through its subsidiary, Career Placement
Registry, Inc. ("CPR"), has developed a database system of infor-
mation concerning college graduates and experienced personnel who
are seeking employment opportunities.  The information had been
made available to the approximately 150,000 subscribers to the
Dialog Information Services of Knight-Ridder, Inc.  Effective
March 1, 1994, Dialog discontinued carrying the database due to
insufficient use.  CPR is currently seeking another carrier. 
Since its creation in 1981, the operations of CPR have not had a
significant impact on the Registrant's earnings.

Other Publishing Activities
- ---------------------------

          Plenum Publishing Company Limited, the Registrant's English 
subsidiary, provides sales representation for the Registrant in the 
United Kingdom and European markets.  Plenum Publishing Company Limited 
also performs editorial procurement services for the scientific book 
and journal publishing programs of the Registrant.

Competition
- -----------

          The market in which the Registrant operates both for the
procurement of manuscripts and the sale of its products is highly 
competitive.  The Registrant is one of the leading publishers and 
distributors of English translations of Russian scientific journals.  
However, several other companies with English translation capabilities 
have relationships with individuals and entities responsible for the 
publication of scientific and technical material in the former Soviet 
Union.  In addition, other publishers in the United States and abroad 
with greater financial resources than the Registrant are engaged in the
publication of original English language scientific materials and
database products, as well as the reprint of out-of-print books
and other books generally not available.

Export Sales
- ------------

          The Registrant's sales derived from customers outside the United 
States aggregated approximately $23,217,000 in 1993 (approximately 43% of 
consolidated sales).  Sales derived from customers outside the United 
States were approximately $21,214,000  in 1992 and $21,453,000 in 1991 
(approximately 39% and 40%, respectively, of consolidated sales).  The 
Registrant generally prices its products sold abroad in U.S. dollars.

Investments in Securities
- -------------------------

          In 1993, the Registrant's dividends, interest income, net 
realized and unrealized gains/losses on marketable securities, and 
equity in the net income (loss) of Gradco Systems, Inc. (the foregoing 
items net of interest expense and other investment-related expenses) 
represented 3.2% of the Registrant's pre-tax income.  In 1992, such 
items (net of interest expense and other investment-related expenses) 
represented 18.4% of pre-tax income.
          The Registrant's excess cash is invested principally in
a portfolio of marketable securities.  Market conditions and the
nature of the investments have an impact on the performance of
the portfolio.  Excess cash is also invested in part, from time
to time, in short-term investments such as time deposits, money
market funds and commercial paper, and in the past has been
invested in U.S. Government securities.  The investments of ex-
cess cash are available for corporate purposes, and have been so
used periodically.  On April 30, 1993 the Registrant's outstand-
ing 6-1/2% convertible subordinated debentures due 2007 were re-
deemed, requiring an expenditure of $40,734,793 which was funded
principally from liquidation of a portion of such investments.  
          The Registrant owns 913,000 shares of Common Stock of
Gradco Systems, Inc. ("Gradco"), an office automation company,
which were acquired by the Registrant during the period October,
1989 through August, 1991.  The acquisitions by the Registrant
have been reported in a Statement on Schedule 13D and amendments
thereto filed jointly with the Securities and Exchange Commission
by the Registrant and by its Chairman, Martin E. Tash, and his
wife, who as of the date hereof had acquired a total of 250,672
shares.  Mr. Tash also has currently exercisable options to
purchase 50,000 additional shares.  The filings are required
because the Registrant and Mr. and Mrs. Tash as a group (the
"Group") beneficially own more than 5% of the outstanding shares
of Gradco (11.7% by the Company and 3.8% by Mr. and Mrs. Tash,
inclusive of his currently exercisable options, as of the date
hereof, for a total of 15.5%).
          In October 1990, in a proxy contest, a five-person slate 
of directors was nominated by the Group in opposition to the 
nominees of Gradco's then current management.  The slate consisted 
of Martin E. Tash (Registrant's Chairman of the Board and Chief 
Executive Officer), Bernard Bressler (Secretary and a director of 
Registrant) and three other individuals not affiliated with Registrant.  
Three nominees of the Group (including Messrs. Tash and Bressler) were 
elected to directorships, constituting a majority of the Board.  
The newly named Board named Mr. Tash as Gradco's Chairman and Chief 
Executive Officer.
          The Group may be deemed to have obtained control of
Gradco in October 1990, as a result of the fact that its nominees
were elected as a majority of Gradco's Board of Directors. 
Gradco's current five-person Board, elected without any opposing
nominees at its October 1993 Annual Meeting, consists of Messrs.
Tash and Bressler, and three other persons.  All of the nominees
were designated as such at the request of the Group, which there-
fore may be deemed to continue to have control of Gradco.
          Registrant has not undertaken any obligations in
connection with Gradco's operations or advanced any funds to it
and does not otherwise engage in business through Gradco.
          The Registrant's investment in Gradco is reflected in
the Financial Statements included herein using the equity method
of accounting.
          Gradco, the Registrant and Mr. Tash are defendants in a
lawsuit which has been brought by certain former management
employees of Gradco.  See Item 3, Legal Proceedings.
                                  -----------------

          In view of the securities investments described above,
the Registrant evaluates its status under the Investment Company
Act of 1940, as amended (the "Company Act"), on an annual basis. 
(Prior to the redemption of the Debentures, such evaluation had
been performed on a quarterly basis, but in view of the signifi-
cant reduction of investments resulting from the redemption, the
Registrant now considers an annual analysis to be sufficient.) 
The Company Act requires the registration with the Securities and
Exchange Commission of, and imposes various substantive restric-
tions on, any "investment company."  The Company Act defines the
term "investment company" to include a company that engages
primarily, or proposes to engage primarily, in the business of
investing, reinvesting or trading in securities.  An "investment
company" may also include a company which engages or proposes to
engage in the business of investing, reinvesting, owning, holding
or trading in securities and which owns or proposes to acquire
investment securities (which for this purpose excludes U.S.
Government securities) having a value that exceeds 40% of the
value of such company's total assets (excluding cash items and
U.S. Government securities), unless the company is primarily
engaged in a business or businesses other than that of investing,
reinvesting, owning, holding or trading in securities.
          The Registrant's principal business continues to be
publishing and distributing advanced scientific and technical
material, and the Registrant is not primarily engaged in invest-
ing, reinvesting or trading in securities.  As of December 31,
1993, investment securities represented less than 40% of the
value of the Registrant's total assets (exclusive of U.S. Govern-
ment securities and cash items), and in any event the Registrant
continued to be exempt from status as an investment company
pursuant to Rule 3a-1 under the Company Act because less than 45%
of the value of its total assets (exclusive of U.S. Government
securities and cash items) consisted of, and less than 45% of its
net income after taxes for the last four fiscal quarters combined
was derived from, securities (other than U.S. Government securi-
ties).

Miscellaneous Information
- -------------------------

          The Registrant currently employs approximately 300 full
time employees.
          Backlog is not significant in the Registrant's business
because orders are filled on a current basis.  The Registrant
does receive payments and on occasion records receivables from 
journal subscribers in advance of the issuance of journals, and the 
amounts appearing on the Registrant's Consolidated Balance Sheets 
as "Deferred Subscription Income" represent these items.  
See Note 1 of Notes to Consolidated Financial Statements.
          The business of the Registrant is not seasonal.  No
material portion of the business of the Registrant is subject to
renegotiation of profits or termination of contracts at the
election of the Government.  Compliance with the provisions
enacted regulating the discharge of materials into the environ-
ment or otherwise relating to the protection of the environment
does not have an effect upon the Registrant.

Item 3.   Legal Proceedings
          -----------------

          (a)  Plenum Publishing Corporation v. Interperiodica,
               -----------------------------------------------
et al.
- ------
          This litigation, which was previously reported in the
Registrant's Report on Form 10-K for the fiscal year ended Decem-
ber 31, 1992, was discontinued with prejudice and without costs
in December 1993, pursuant to the Journal Production and Distrib-
ution Agreement described in Item 1, Business, under "Subscrip-
                                     --------
tion Journals."

          (b)  Stewart, et al. v. Gradco Systems, Inc.,
               ---------------------------------------
Plenum Publishing Corporation, et al.
- ------------------------------------

          As the result of the proxy contest in October 1990,
described above in Item 1, Business, under "Investments in
Securities", the composition of the Board of Directors of Gradco
Systems, Inc. ("Gradco") was changed.  Among such changes were
the election of Martin E. Tash, the Registrant's Chief Executive
Officer, to the Gradco Board, and the non-renewal of Keith
Stewart as a member of the Gradco Board.  Mr. Tash succeeded Mr.
Stewart as Chief Executive Officer of Gradco.
          In December 1990, Gradco asserted claims in the Superi-
or Court of California against Mr. Stewart and others, alleging a
conspiracy on their part to defraud Gradco of a substantial part
of its assets.  Mr. Stewart was charged with converting Gradco
funds to satisfy his personal obligations and other wrongful
actions, including defaulting on a promissory note in Gradco's
favor.  The aggregate of the allegedly converted funds exceeds
$1,000,000.  The complaint, among other things, also seeks a
declaration that no payments are due under "golden parachute"
agreements which are claimed to have been wrongfully obtained.
          Certain of Gradco's former employees, including Mr.
Stewart, have instituted actions in the Superior Court of Cali-
fornia against Gradco, Mr. Tash and the Registrant, claiming,
among other things, the breach of the above-referenced "golden
parachute" agreements.  The stated aggregate claims for compensa-
tory damages by said former employees exceeds $20,000,000.  Of
that sum, approximately $2,500,000 is attributable to the afore-
said alleged breach of the "golden parachute" agreements.  The
balance is principally attributed to various causes of action
arising from the same set of facts, including such claims as bad
faith denial of contract existence, conspiracy to induce breach
of contract, and intentional infliction of emotional distress. 
Gradco, the Registrant and Mr. Tash have denied all liability and
have interposed various affirmative defenses.  The claims by one
of the former employees have been settled, with Gradco being
responsible for the settlement payments.
          Pre-trial discovery is being conducted with respect to
the aforesaid matters in dispute, and the discovery cutoff date
is June 30, 1994.  A trial date has not yet been set.  Management
of the Registrant, after consultation with counsel, believes that
the action will not result in a material loss to the Registrant
and intends to vigorously defend against it.

dividends are dependent upon the Registrant's earnings, general
financial condition and the requirements of the business and upon
declaration of the dividend from time to time by the Board of
Directors.

Item 7. Management's Discussion and Analysis of Financial
        Condition and Results of Operations
        --------------------------------------------------
Results of Operations
- ---------------------

1993 Compared to 1992
- ---------------------

        Revenues from the Company's publishing operations in-
creased by 0.7% to $54,098,246.  Revenues from subscriptions and
outside journals increased by 2.4%, primarily attributable to 
more journal issues being published and higher selling prices,
offset by non-renewals of subscriptions partially due to the
reduced buying power of libraries.  Revenues from book sales
decreased by 6.2% primarily due to fewer book titles being
published.
        In December 1993, the Company entered into a Journal
Production and Distribution Agreement (the "Distribution Agree-
ment") with the Russian Academy of Sciences (the "Academy") and
other interested parties pursuant to which the litigation then
pending, relating to the translation of Russian scientific
journals, was ended, and the Company's role as publisher and
distributor of certain of such journals was altered.  The Distri-
bution Agreement extends from 1994 through 2006.
        Pursuant to the Distribution Agreement, in 1994 the
Company will distribute for MAIK Nauka ("MN"), an entity owned in
part by Pleiades Publishing, Inc. and the Academy, 21 Russian
scientific journals in English.  MN will become the exclusive
publisher of such journals.  Prior thereto, the Company had
translated, published and distributed these journals under a con-
tract with the Copyright Agency of the former Soviet government,
and under contracts with the individual institutes publishing the
journals, and had paid royalties based in part upon the number of
subscribers.  Under the Distribution Agreement, the Company will
continue to promote and distribute these journals throughout the
world, and will continue to deal with and collect from subscribers
to the journals, retaining a portion of such revenues for performing 
its function.  In 1994, the Company will retain 35% of the revenue, 
with the amount gradually being reduced to 30% in 1999 and remaining 
at that level for the balance of the term of the Distribution Agreement.  
Revenue from such 21 journals in the 1993 journal year constituted 6.7% 
of the Company's overall journal revenue and 16.2% of its Russian 
journal revenue.  Nine of such journals were being published by both the 
Company and the predecessor of MN under conflicting contracts and were 
the subject of the above-mentioned litigation.
        Under the Distribution Agreement, in 1995 and 1996 MN will
undertake the publication of the English translations of 11
additional Russian journals, to be promoted and distributed by
the Company, representing a total of an additional 13.7% of the
Company's 1993 Russian journal revenue and 5.6% of its total
journal revenue.  Commencing in such years, MN  may elect to
publish the English translations of up to 23 additional Russian
journals, to be promoted and distributed by the Company.  The
total revenue from these 23 journals equals 29.2% of the Comp-
any's 1993 Russian journal revenue and 11.9% of its total journal
revenue. As to each additional journal which is published by MN 
and distributed by the Company under the Distribution Agreement, 
the Company will retain 35% of the revenue in the initial year 
of distribution, with the amount gradually being reduced to 30% 
over a six-year period.
        MN intends to cause the above-mentioned journals to be
translated and published in the former Soviet Union.  The Company
will continue its activities in translating, publishing and
distributing both the journals subject to the Distribution
Agreement until they are published by MN and the approximately 40
English Translation Russian Journals not subject to the Agreement.
These activities will be undertaken pursuant to the Company's 
existing English translation and publication contracts with the 
individual entities publishing the Russian language journals which 
generally extend through 2001.
        Management expects that in 1994 and thereafter, revenues
and net income from subscription journals will decrease as a
result of the Company's modified relationship to the translation
journals covered by the Distribution Agreement, and also as a
result of the political and economic situation in Russia and in
the other republics of the former Soviet Union.
        In April 1993, an American learned society with whom the
Company had a contract to produce English translations of 11
Russian language journals for publication by that society gave
formal notice that they would not exercise the option of renewing
the contract beyond the term ending with the 1993 volume year. 
For fiscal 1993, the amount of revenue generated from the produc-
tion of these 11 journals was approximately $1,261,000; however,
such revenue will cease during fiscal 1994.
          The cost of sales as a percentage of revenues increased
from 39.82% to 40.08%, primarily due to higher salaries and
employee benefit costs, offset by a more favorable mix of reve-
nues from subscriptions and outside journals and book sales.  The
increase in royalty expenses was principally due to increased
royalty rates.  The decrease in selling, general and administra-
tive expenses was primarily attributable to decreased profession-
al fees and bad debt expense, offset by higher salaries, employee
benefit costs and sales commissions.
        The decrease in interest income was principally due to
lower interest rates and decreased investments in Government
securities, time deposits and money market funds, arising in
large part because of the decrease in investment assets utilized
for redemption of the Company's 6-1/2% Convertible Subordinated
Debentures on April 30, 1993.  The increase in dividend income
resulted from the increase in average investment in marketable
securities in 1993.  The Company had a net realized gain of
$801,387 on marketable securities and recorded a provision of
$1,713,197 for net unrealized losses on marketable securities 
for 1993, as compared to a net realized gain of $2,476,916 on 
marketable securities for 1992.  The decrease in interest expense 
was primarily due to the redemption of the Debentures.
          The decrease in net income was principally attributable
to the decrease in investment income as discussed in the preceding
paragraph and the extraordinary loss from early retirement of
6-1/2% Convertible Subordinated Debentures.  The provision for
income taxes as a percentage of income decreased in 1993 as
compared to 1992 because in 1992 the Company recorded an additional 
provision for state and local income taxes for assessments of such 
taxes expected with respect to prior years.
          In May 1993, the Financial Accounting Standards Board
issued statement of Financial Accounting Standards No.115,
"Accounting for Certain Investments in Debt and Equity Securities,"
effective for fiscal years beginning after December 15, 1993.
Under the new rules, which the Company will adopt effective 
January 1, 1994, the Company will classify its marketable equity
securities held as trading securities on the basis of its intent
to trade such securities. Accordingly, all marketable equity
securities classified as trading securities will be carried at fair
market value. Unrealized gains and losses applicable to these 
securities will be reported  as a component of current earnings.
Presently, the Company values marketable equity securities as trading
securities and reports such securities at the lower of aggregate cost
or market, with unrealized losses reported as a component of current 
earnings.

1992 Compared to 1991
- ---------------------

        Revenues from the Company's publishing operations increased 
by 0.7% to $53,725,999.  Revenues from subscriptions and outside 
journals increased by 2.3%, primarily attributable to higher selling 
prices, offset by non-renewals of subscriptions partially due to the 
impact of the recession on the buying power of libraries and individuals, 
and fewer journal issues being published.  Revenues from book sales 
decreased by 5.3% primarily due to fewer book titles being published.  
Revenues from database products increased by 9.7%, primarily due to 
increased prices.
        The cost of sales as a percentage of revenues increased from
39.56% to 39.82%, primarily due to higher salaries and employee benefit 
costs, offset by a more favorable mix of revenues from subscriptions 
and outside journals and book sales, and increased prices of database 
products.  The increase in royalty expense was principally due to 
increased royalty rates and higher costs associated with extended 
English translation and publication agreements with Institutes publishing 
scientific journals in Russia.  The insignificant decrease in selling,
general and administrative expenses was primarily attributable to
lower sales commissions, advertising expenditures, computer expenses 
and mailing expenses, offset by higher salaries and employee benefit 
costs and increased professional fees.
        The decrease in interest income was principally due to lower 
interest rates.  The increase in dividend income was due to increased 
investment in marketable securities.  The Company had a net realized 
gain of $2,476,916 on marketable securities for 1992, as compared to a
net realized gain of $19,714 and a reversal of the provision of $6,544,417
for net unrealized loss on marketable securities for 1991. The decrease 
in interest expense resulted from the repurchase of $6,808,000 of 6 1/2% 
Convertible Subordinated Debentures due April 15, 2007.
        The decrease in net income was principally due to the decrease 
in investment income discussed in the preceding paragraph, decreased 
income from publishing operations and an increase in the provision for 
income taxes as a percentage of income, offset by the cumulative effect 
on prior years of accounting change for deferred income taxes and 
extraordinary credit arising from the repurchase of 6 1/2% Convertible 
Subordinated Debentures.  The provision for income taxes as a percentage 
of income increased because the reversal of net unrealized losses on 
marketable securities in 1991 was exempt from income taxes to the extent 
that said losses, when incurred in 1990, had no deferred tax benefits 
recognized, and in 1992 the Company recorded an additional provision 
for state and local  income taxes for assessments of such taxes expected 
with respect to prior years.

Liquidity and Sources of Capital
- --------------------------------

        The ratio of current assets to current liabilities is 6.3 to 1 
at December 31, 1993 compared to 2.1 to 1 at December 31, 1992.
        Management anticipates that internally generated funds will 
exceed requirements of the operations of the business.  The Company 
also has funds of approximately $53,855,000 at December 31, 1993 
invested in marketable securities and in cash, which are available for 
corporate purposes.
        On April 30, 1993 (the "Redemption Date"), pursuant to a
notice of election to redeem which had been given to the holders
on March 24, 1993, the Company redeemed the Debentures which were
outstanding on the Redemption Date.  In accordance with the terms
of the Debentures and the applicable Trust Indenture, the redemp-
tion required a total payment of $40,734,793 (representing the
redemption price of 102.60% of the principal amount of outstanding
Debentures and accrued interest from April 15 to April 30, 1993).
This amount was funded by liquidating a portion of the Company's
investments of its excess cash, and from short-term borrowing on
the Company's margin account with a broker.

Footnotes to Summary Compensation Table
- ---------------------------------------

(1)Represents amounts paid to the named executive officer, for the
applicable fiscal year, under the Registrant's Incentive Compensation 
Plan.  For each fiscal year an amount equal to 5% of the Registrant's 
Income from Operations as reported in the Registrant's year-end 
financial statements (together with, when applicable, 5% of the excess 
of cumulative Investment Profit over cumulative Investment Loss) is 
distributed to key employees. Thirty-five percent of such amount is 
distributed to the chief executive officer and 25% is distributed to 
the next senior officer.  The balance of such amount is distributed as 
determined by the chief executive officer.  Since cumulative Investment
Profit (as defined) earned after 1990, through December 31, 1992,
exceeded Investment Loss (as defined) incurred in 1990, the excess was 
added to Income from Operations for the purpose of calculating incentive 
compensation for 1992.  Since there was Investment Profit (as defined) 
in 1993, the amount of such Profit was added to Income from Operations 
for the purpose of calculating incentive compensation for 1993.

(2)Represents amount of contribution made to or accrued for the account 
of the named executive officer, in respect of the applicable fiscal year, 
in the Registrant's Profit Sharing Plan (a defined contribution plan 
qualified under the Internal Revenue Code).  The Plan is maintained for 
all full-time employees who have completed certain minimum periods of 
service.  The Registrant contributes to the Plan specified amounts based 
upon its after tax income as a percentage of gross revenue.  The 
Registrant's contribution to the Plan for each employee is determined
by his salary level and length of service.  Contributions are
invested by the Plan Trustee in stock of the Registrant and/or in a
variety of other investment options, depending upon the employee's 
election.  Interests in the Plan become vested to the extent of 20% 
after three years of service and vest at the rate of an additional 
20% for each year of service thereafter and in any event become 100% 
vested at death or at the "normal retirement age" of 55 as specified 
in the Plan.  Each employee (or his beneficiary) is entitled to receive 
the value of his vested interest upon his death or retirement.  He may 
also receive the value of such interest upon prior termination of his 
services with the Registrant, or if he elects at any time to withdraw his
interest.  The interests of Messrs. Tash, Shaw, and Patel are fully vested.

         The aggregate contributions made or accrued by the Registrant 
through the end of fiscal 1993 for Messrs. Tash, Shaw and Patel under 
this Plan are $405,650, $425,525 and $109,694, respectively; these 
contributions have been invested in the manner set forth above, and 
(as to Mr. Shaw) a portion of the investments was transferred from the 
Plan into a private profit sharing plan of which Mr. Shaw is the beneficiary.

              (b)  Compensation of Directors.
                   -------------------------

              Directors fees for Dr. N. Bruce Hannay and Messrs. Earl
Ubell and Howard F. Mathiasen are currently at the rate of $9,500 per
annum each.  Directors of the Registrant who are also officers of the 
Registrant receive no additional compensation for their services as 
directors.
              
              (c)  Termination of Employment and Change of Control
                   Arrangements Regarding Named Executive Officers.
                   ------------------------------------------------

               (i)  See footnote (2) to table in Item 11(a) for
information as to entitlement of Messrs. Tash, Shaw and Patel to
receive certain distributions under the Registrant's Profit Sharing 
Plan upon termination of their employment.
              
              (ii)  On September 22, 1989, the Registrant adopted
Amended Contingent Compensation Agreements with Martin Tash and Mark 
Shaw (executive officers of the Registrant named in the table in 
item 11(a)) and with Harry Allcock and Marshall Lebowitz (officers 
of subsidiaries of the Registrant).  The Amended Agreements supersede 
the Contingent Compensation Agreements, adopted on October 8, 1986, 
and provide that if (a) during the officer's employment or within six 
months after his employment terminates, there is a sale of 75% of the 
book value of the Registrant's operating assets (as defined), or if 
any person or group becomes the owner of over 25% of the Registrant's 
outstanding stock, and (b) the officer's employment is terminated at 
or prior to the end of the sixth month after such event, then the 
Registrant shall pay the terminated officer cash equal to 290% of the 
officer's average annual taxable compensation over the preceding five
calendar years.  The Amended Agreements add a provision specifying 
that a successor in interest to the Registrant would remain liable 
thereunder.  They are otherwise substantially identical to the original 
Agreements.
              On December 14 1993, the Registrant entered into Contingent 
Compensation Agreements with Ghanshyam Patel (an executive officer of the 
Registrant named in the table in item 11(a)) and Ken Derham (an officer 
of a subsidiary of the Registrant) on the same terms as the Amended 
Agreements described above.

              (d)  Indemnification Agreements.
                   --------------------------

              In September 1987, the Registrant's liability insurance
for its directors and officers expired and was not renewed due to the
significantly increased cost.  In light of this development, and to
provide increased protection, the Registrant's By-Laws were amended
on November 18, 1987 to require the Registrant to advance expenses
of directors or officers in defending a civil or criminal action as
such expenses are incurred, subject to certain conditions.
Furthermore, on that date the Registrant entered into a contract
with each of its directors and executive officers, requiring
indemnification for expenses, judgments, fines and amounts paid in
settlement, in accordance with the By-Laws as ameded, or any
future By-Laws which provide greater indemnification. (On December
14, 1993, the Registrant entered into a substantially identical
contract with an officer of one of its subsidiaries.) The present
By-Laws provide for such indemnification, in connection with claims 
arising from service to the Registrant, or to another entity at 
Registrant's request, except where it would be prohibited under 
applicable law.
              
              (e)  Compensation Committee Interlocks and Insider
                   Participation
                   ---------------------------------------------

              The Registrant's Board of Directors has no compensation
committee (or other Board committee performing equivalent functions);
compensation policies applicable to executive officers are determined 
by the Board.  During the fiscal year ended December 31, 1993, the 
officers of the Registrant participating in the Board's deliberations 
concerning executive compensation were Martin E. Tash, Mark Shaw and 
Bernard Bressler (who are members of the Board).
              During the fiscal year ended December 31, 1993, Martin
E. Tash (an executive officer of the Registrant) served as a
member of the Board of Directors of Gradco Systems, Inc. ("Gradco").  
Gradco has no compensation committee (or other Board committee 
performing equivalent functions); compensation policies applicable 
to executive officers are determined by its Board.  Mr. Tash 
is an executive officer of Gradco and is the only such executive 
officer who also served on Registrant's Board.  Bernard Bressler 
(Secretary and a director of Registrant) is an officer and director 
of Gradco, but he is not an executive director of either entity.
              During the period since January 1, 1993, there were no
transactions between the Registrant and Gradco of the type
required to be disclosed under Item 13, Certain Relationships and
Related Transactions.

         registered under the Investment Advisers Act of 1940.  It
         has sole voting power and no dispositive power as to 218,000

         13G, all of the aforesaid securities "are owned legally by
         Southeastern's investment advisory clients and none are
         owned directly or indirectly by Southeastern.  As permitted
         by Rule 13d-4, the filing of this statement shall not be
         construed as an admission that Southeastern is the beneficial 
         owner of any of [such] securities."  The Schedule 13G was also 
         filed by O. Mason Hawkins, Chairman of the Board and President 
         of Southeastern "in the event he could be deemed to be a 
         controlling person of that firm as the result of his official 
         position with or ownership of voting securities.  The existence 
         of such control is expressly disclaimed.  Mr. Hawkins does not

         statement for his own account.  As permitted by Rule 13d-4, 
         the filing of this statement shall not be construed as an 
         admission that Mr. Hawkins is the beneficial owner of any of 
         the securities covered by this statement."  The Schedule 13G 
         reflects that Mr. Hawkins has voting or dispositive power as 
         to none of the Registrant's shares.

         and dispositive power as to 37,500 of the shares shown above, 
         representing 0.83% of the outstanding Common Stock.  The Schedule

                        Report of Independent Auditors

Stockholders and Board of Directors
Plenum Publishing Corporation

We have audited the accompanying consolidated balance sheets of Plenum 
Publishing Corporation and subsidiary companies as of December 31, 1993 
and 1992, and the related consolidated statements of income, stockholders' 
equity and cash flows for each of the three years in the period ended 
December 31, 1993. Our audits also included the financial statement
schedules listed in the Index at Item 14(a). These financial statements
and schedules are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these financial statements
and schedules based on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are 
free of material misstatement. An audit includes examining, on a test basis,  
evidence supporting the amounts and disclosures in the financial 
statements.  An audit also includes assessing the accounting principles 
used and significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the consolidated financial 
position of Plenum Publishing Corporation and subsidiary companies at 
December 31, 1993 and 1992, and the consolidated results of their
operations and their cash flows for each of the three years in the 
period ended December 31, 1993, in conformity with generally accepted
accounting principles.  Also, in our opinion, the related financial
statement schedules, when considered in relation to the basic

Depreciation is provided for by the straight-line method or by the declining-
balance method over estimated useful lives ranging from 3 to 35 years. 
Amortization of leasehold improvements is provided for by the straight-line 
method generally over the terms of the related leases or the estimated useful 
lives of the improvements, whichever period is shorter.

The excess of cost of assets acquired over book amount thereof (which arose 
in connection with various acquisitions by the Company in prior years, other 
than Gradco Systems, Inc.) is being amortized by the straight-line method 
principally over forty years.

Deferred expenses relating to issuance of long-term debt are being amortized 
by the straight-line method over the term of the related debt (see Note 6).

The cost of the subscription lists of Human Sciences Press and Agathon 
journals is being amortized by the straight-line method over estimated 
useful lives ranging from 12 to 20 years.

Other assets include the cost of rights to produce and distribute certain 
journals, which is being amortized by the straight-line method, primarily 
over a period of fifteen years.

Deferred Subscription Income
- ----------------------------

The Company bills subscribers to certain publications and patent information 
services in advance of issuance thereof. The publications are generally 
issued over a one-year period and subscription revenues are taken into 
income by the straight-line method based on the relationship of the number 
of publications issued to the number ordered by subscribers. Patent 
information service revenues are taken into income when published.

The portion of advance billings which will require use of financial resources 
within one year is not practicable to determine and, accordingly, no portion 
thereof is included in current liabilities; expenditures at balance sheet 
dates in respect of such advance billings have similarly been excluded from 
current assets.

Marketable Securities
- ---------------------

Marketable securities are valued at the lower of aggregate cost or market. 
Gains and losses on marketable securities are determined based on specific 
identification. See Note 2.

Cash Equivalents and Supplemental Cash Flow Information
- -------------------------------------------------------

The Company considers all highly liquid financial instruments with a 
maturity of three months or less when purchased to be cash equivalents. 
As of December 31, 1993, the Company had time deposits and money market 
accounts totalling approximately $1,442,000 on deposit with five financial 
institutions. As of December 31, 1992, the Company had time deposits and 
money market accounts of approximately $10,057,000 on deposit with four 
financial institutions.

The Company paid income taxes in 1993, 1992 and 1991 of approximately 
$6,029,000, $5,962,000 and $6,915,000 (net of income tax refunds received 
of approximately $1,218,000 in 1991), respectively. In addition, the 
Company paid interest in 1993, 1992 and 1991 of approximately $1,565,000, 
$3,023,000 and $3,200,000, respectively.

2. Accounting Change
- --------------------

In February 1992, the Financial Accounting Standards Board issued Statement 
No. 109, "Accounting for Income Taxes" (the "Statement"). The Company adopted 
the provisions of the new standard in its financial statements for the year 
ended December 31, 1992. As permitted by the Statement, prior year financial 
statements have not been restated to reflect the change in accounting method. 
The cumulative effect as of January 1, 1992 of adopting the Statement 
increased net income by $1,179,950 or $.25 per share ($.19 per share on 
a fully diluted basis).

Under the Statement, the liability method is used in accounting for income 
taxes. Under this method, deferred tax assets and liabilities are determined 
based on differences between financial reporting and tax bases of assets 
and liabilities and are measured using the enacted tax rates and laws that 
will be in effect when the differences are expected to reverse. Prior to 
the adoption of the Statement, income tax expense was determined using the 
liability method prescribed by Financial Accounting Standards Board Statement 
No. 96 ("Statement 96"), which is superseded by the Statement. Among other 
matters, the Statement changes the recognition and measurement criteria for 
deferred tax assets included in Statement 96. In accordance with the 
Statement, all of the income tax benefits on the excess of book over tax 
deductions (for example, depreciation, allowance for doubtful accounts, 
etc.) are deferred (see Note 7). The cumulative effect on prior years of 
the change has been shown in the income statement for 1992.

In May 1993, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 115, "Accounting for Certain 
Investments in Debt and Equity Securities," effective for fiscal years 
beginning after December 15, 1993. Under the new rules, which the Company 
will adopt effective January 1, 1994, the Company will classify its 
marketable equity securities held as trading securities on the basis of 
its intent to trade such securities.

Accordingly, all marketable equity securities classified as trading 
securities will be carried at fair market value. Unrealized gains and 
losses applicable to these securities will be reported as a component 
of current earnings.

Presently, the Company values marketable equity securities as trading 
securities and reports such securities at the lower of aggregate cost 
or market, with unrealized losses reported as a component of current 
earnings.

6. Long-Term Debt
- -----------------

Long-term debt at December 31, 1992 consisted of 6-1/2% Convertible 
Subordinated Debentures (the "Debentures") due April 15, 2007. The 
Debentures were issued in April and May 1987.

In 1993, 1992 and 1991, the Company purchased Debentures in the principal 
amount of $1,149,000, $6,808,000 and $1,300,000, respectively, for an 
aggregate cost (including the write-off of related deferred issuance costs 
of approximately $28,000, $173,000 and $34,000, respectively) of 
approximately $1,143,000, $6,149,000 and $1,134,000, respectively.

On April 30, 1993 (the "Redemption Date"), pursuant to a notice of election 
to redeem which had been given to the holders on March 24, 1993, the Company 
redeemed the Debentures which were outstanding on the Redemption Date. In 
accordance with the terms of the Debentures and the applicable Trust 
Indenture, the redemption price was equal to 102.60% of the principal amount 
of outstanding Debentures, and the holders were also paid accrued interest 
for the period from April 15, 1993 (the date on which the last semiannual 
installment of interest was paid) to the Redemption Date. Prior to the 
Redemption Date, Debentures in the aggregate principal amount of $80,000 
were converted into 2,560 shares of Common Stock at the applicable conversion 
rate of $31.25 per $1,000 of principal amount. On the Redemption Date, 
Debentures in the aggregate principal amount of $39,598,000 were outstanding, 
requiring a total payment to the holders of approximately $40,735,000 
(including accrued interest). This amount was funded by liquidating a 
portion of the Company's investments of its excess cash, and from short-term 
borrowing on the Company's margin account with a broker.

The premium paid for the Debentures, and the write-off of related deferred 
issuance costs of approximately $956,000, net of applicable income tax 
benefit of $675,000 totalled approximately $1,310,000, which has been 
accounted for as an extraordinary loss.

7. Income Taxes

Effective January 1, 1992, the Company changed its method of accounting for 
income taxes to the liability method required by FASB Statement No. 109,

of timing differences in reporting transactions for financial and tax 
purposes.  A description of the differences and the related tax effect 
follow:

9. Profit Sharing and Incentive Compensation Plans
- --------------------------------------------------

The Company has a profit sharing plan for its employees which provides for 
annual contributions based upon the Company's net income as a percentage of 
gross revenue and the employees' salary level and length of service. Such 
contributions, which are placed in a trust fund, are invested at the 
employees' discretion. Contributions under the plan aggregated approximately 
$1,121,000 (1993), $1,126,000 (1992) and $1,006,000 (1991). Other accrued 
expenses and sundry liabilities include accrued contributions under the plan 
of $1,121,000 (1993) and $1,126,000 (1992).

The Company has an incentive compensation plan for executive officers and key 
employees of the Company providing for 5% of the Company's income from 
operations to be distributed (as provided) to participants of the plan. In 
addition to the amounts payable as set forth above, since cumulative 
investment income (as defined) earned after 1990 through December 31, 1992 
exceeded investment loss (as defined) incurred in 1990, the excess was added 
to income from operations for the purpose of calculating incentive compen-
sation for 1992. Since there was investment income (as defined) in 1993, the 
amount of such income was added to income from operations for the purpose of 
calculating incentive compensation for 1993. Distributions under the plan 
aggregated $844,000 (1993), $959,000 (1992) and $821,000 (1991). Other 
accrued expenses and sundry liabilities include accrued incentive 
compensation of $339,000 (1993) and $464,200 (1992).

The Company has the right to change, modify or terminate the above plans at 
any time.

10. Per Share Amounts
- ---------------------

Primary net income per share of Common Stock is computed on the basis of 
weighted average number of common shares outstanding (4,607,458 (1993), 
4,727,714 (1992) and 5,030,844 (1991)).

Amounts per share of Common Stock assuming full dilution are computed on the 
basis of the weighted average number of shares set forth in the preceding 
paragraph adjusted for shares issuable upon conversion of the Convertible 
Subordinated Debentures, after elimination from net income of related debt 
expense thereon, less applicable income taxes. The number of shares used in 
this computation is 5,003,791 (1993), 6,166,436 (1992) and 6,592,579 (1991).

Fully diluted net income per share is not presented for the periods where 
the result of the computation is antidilutive.

The net unrealized gain at December 31, 1992 has not been recognized in 
the accompanying consolidated financial statements; such amount consisted

The Company's portfolio of marketable securities is substantially invested 
in a limited number of issuers, operating principally in the pharmaceutical 
industry at December 31, 1993 and in the pharmaceutical and electric utility 
industries at December 31, 1992. At December 31, 1993, the cost and market 
value of the Company's largest holding (invested in a company operating in 
the pharmaceutical industry) were $21,000,000 and $21,749,000, respectively 
($18,422,000 and $23,154,000, respectively, at December 31, 1992).

Subsequent to December 31, 1993 and through March 14, 1994, the Company 
realized net losses aggregating approximately $904,000 on sales of marketable 
securities. At March 14, 1994, the market value of marketable securities 
aggregated approximately $39,844,000 (cost $41,635,000).

13. Distribution Agreement
- --------------------------

In December 1993, the Company entered into a Journal Production and 
Distribution Agreement (the "Distribution Agreement") with the Russian 
Academy of Sciences (the "Academy") and other interested parties pursuant 
to which the litigation then pending, relating to the translation of Russian 
scientific journals, was ended, and the Company's role as publisher and 
distributor of certain of such journals was altered. The Distribution 
Agreement extends from 1994 through 2006.

Pursuant to the Distribution Agreement, in 1994 the Company will distribute 
for MAIK Nauka ("MN"), an entity owned in part by Pleiades Publishing, Inc. 
and the Academy, 21 Russian scientific journals in English. MN will become 
the exclusive publisher of such journals. Prior thereto, the Company had 
translated, published and distributed these journals under a contract with 
the Copyright Agency of the former Soviet government, and under contracts 
with the individual institutes publishing the journals, and had paid 
royalties based in part upon the number of subscribers. Under the 
Distribution Agreement, the Company will continue to promote and distribute 
these journals throughout the world, and will continue to deal with and 
collect from subscribers to the journals, retaining a portion of such 
revenues for performing these functions. In 1994, the Company will retain
35% of the revenue, with the amount gradually being reduced to 30% in 1999 
and remaining at that level for the balance of the term of the Distribution 
Agreement. Pursuant to the Distribution Agreement, the Company advanced the 
Academy $1,000,000 during 1993, of which, $750,000 was outstanding at 
December 31, 1993.

Under the Distribution Agreement, in 1995 and 1996 MN will undertake the 
publication of the English translations of 11 additional Russian journals, 
to be promoted and distributed by the Company. Commencing in such years, MN 
may elect to publish the English translations of up to 23 additional Russian 
journals, to be promoted and distributed by the Company. As to each 
additional journal which is published by MN and distributed by the Company
under the Distribution Agreement, the Company will retain 35% of the revenue
in the initial year of distribution, with the amount gradually being reduced
to 30% over a six-year period.

MN intends to cause the above-mentioned journals to be translated and 
published in the former Soviet Union. The Company will continue its 
activities in translating, publishing and distributing both the journals 
subject to the Distribution Agreement until they are published by MN and the 
approximately 40 English Translation Russian Journals not subject to the 
Agreement. These activities will be undertaken pursuant to the Company's 
existing English translation and publication contracts with the individual 
entities publishing the Russian language journals which generally extend 
through 2001.

14. Contingencies
- -----------------

The Company has contingent compensation agreements with certain key personnel. 
Each agreement provides for the cash payment of an amount equal to 290% of 
average annual compensation (as defined), in the event of termination of 
employment, under certain conditions which include, among other matters, (a) 
the sale of 75% of the book value of the Company's operating assets (as 
defined) or (b) any person (as defined) becoming the owner of more than 25% 
of the issued and outstanding shares of the Company's voting stock.

In 1991, the Company was named as a co-defendant in an action brought by 
former executives of Gradco, seeking compensatory and other damages of a 
material amount. Management of the Company, after consultation with counsel, 
believes the action will not result in a material loss to the Company and 
intends to vigorously defend against it.

(2) The average amount outstanding during the period was computed by dividing the total of daily outstanding
    principal balances by the number of days during the period.

(3) The weighted average interest rate during the period was computed by dividing the actual interest expense
    by average short-term debt outstanding.
