Over the Long Term -- J. & W. Seligman & Co. Incorporated

- --------------------------------------------------------------------------------

TIME IS THE TEST

   In an industry that has changed dramatically in recent years, it's comforting
to know that stability, tradition, and consistent professional service can still
be found in an investment management firm.

   J. & W. Seligman & Co. Incorporated has been providing financial services for
more than 130 years. From its beginning, Seligman has followed a long-term
approach to making money for its clients, by managing investment products and
services of the highest quality. Today, Seligman manages the Seligman Group of
Funds, which offers investors more than 50 investment options.

A PLACE IN HISTORY

   Established in 1864, Seligman played a major role in the geographical
expansion and industrial development of the United States. The firm helped
finance the westward path of the railroads and the building of the Panama Canal.
In the late 1800s and early 1900s, the firm was instrumental in financing the
fledgling automobile and steel industries. Seligman also participated in the
original underwritings for some of the nation's most prominent companies,
including General Motors, Victor Talking Machine, United Artists Theater
Circuit, and Maytag. In 1929, Seligman introduced Tri-Continental Corporation --
which today is the nation's largest diversified closed-end investment company.
In 1930, Seligman began managing its first mutual fund, Broad Street Investing
Co., now known as Seligman Common Stock Fund.

SELIGMAN COMMUNICATIONS AND INFORMATION FUND

   Seligman Communications and Information Fund, established June 23, 1983,
seeks capital gain by investing primarily in the securities of companies
operating in all aspects of the communications, information, and related
industries. Since its inception, Seligman Communications and Information Fund

To the Shareholders

   Nineteen ninety-seven was a challenging but rewarding year for Seligman
Communications and Information Fund. The Fund posted a 22.95% total return based
on the net asset value of Class A shares. This return significantly outperformed
the 10.65% average total return of its peers, as measured by the Lipper Science
& Technology Funds Average.

   This was the seventh year of economic expansion in the US, with real domestic
growth of 3.8%. Consumer price inflation slowed to under 2%, interest rates
moved steadily lower, productivity rose, and unemployment levels reached 27-year
lows. Meanwhile, the federal budget deficit virtually disappeared and corporate
profits posted a third consecutive year of strong gains. Despite year-end
problems in Asia, the domestic business environment was favorable.

   During 1997, the equity markets, as measured by the Standard & Poor's 500
Composite Stock Price Index, had a total return of 33.36%. However, much of this
gain occurred in the first seven months. Technology stocks, in particular, were
subject to wide fluctuations throughout the year, with selloffs in the sector
from February to May, and again in November and December. Within the technology
sector, the largest companies were generally the strongest performers due to
their more reliable earnings profiles. However, not all large-capitalization
technology stocks had a successful year, and earnings disappointments triggered
severe price corrections in select stocks.

   The last quarter of the year was the most difficult, as negative earnings
announcements from bellwether stocks such as Oracle Systems and fears regarding
the impact of the Asian crisis on the sector led to a pronounced selloff of
technology stocks. Semiconductor companies, which had performed strongly until
October, were particularly affected by the anticipated reduction in Asian demand
for technology. Further, the growing popularity of low-cost personal computers
(PCs) caused concern regarding the future profitability of PC manufacturers.
Nevertheless, technology stocks ended the year with a rally, as investors took
advantage of the buying opportunities found in the sector.

   Although technology stocks were seriously impacted in the aftermath of the
October 27, 1997, stock market correction, we believe there remains a great deal
of opportunity in the sector. However, it is possible that certain areas within
the technology universe will be adversely impacted by the Asian crisis. The
Fund's new investments will, therefore, be more focused on domestically-oriented
stocks that are not as dependent on the Asian markets for growth.

   The outlook for US corporate profits in 1998 is uncertain due to expectations
of more modest economic growth and the unforeseeable effect of the Asian crisis
on corporate profitability and the economy. There is a risk of temporary price
deflation linked to the Asian crisis, as those economies seek to export their
way out of trouble. Barring problems caused by the tightness of the labor
market, we expect a continuation of the current low-inflation and
low-interest-rate environment.

   We believe that difficult market environments will highlight the strengths of
active management. Volatility can also serve as a reminder of the importance of
a long-term investment strategy, putting the short-term fluctuations of the
markets and technology stocks in perspective. While the degree of the day-to-day
changes that affect technology stocks can be intimidating, it serves to remember
that there is a risk/reward tradeoff. The Fund, while vulnerable to the market's
temporary gyrations, has historically offered superior returns over the long
term. Finally, creating and maintaining a personal investment portfolio that is
diversified across asset classes and industry groups can limit the impact of
shifts in the market environment.

   Thank you for your continued interest in Seligman Communications and
Information Fund. We look forward to serving your investment needs in the many
years to come. A discussion with your Portfolio Manager, the Fund's portfolio of
investments, and financial statements, follow this letter. Additional

Interview With Your Portfolio Manager, Paul H. Wick

Q. How did Seligman Communications and Information Fund perform in 1997?

A. Seligman Communications and Information Fund's total return based on the net
   asset value of Class A shares was 22.95% for the year. While the Fund vastly
   outperformed the 10.65% average total return of its peers, as measured by the
   Lipper Science & Technology Funds Average, it lagged the 33.36% total return
   of the Standard & Poor's 500 Composite Stock Price Index. After an auspicious
   start to the second half of the year, technology stocks gave up significant
   ground late in the fourth quarter as the Asian financial crisis intensified.

Q. Which of the Fund's industries performed best in 1997?

A. The clear standout in 1997 was the radio broadcasting industry, which
   benefited from a strong advertising market and continued consolidation.

      Also posting favorable results was the data storage market, where Fund
   holdings benefited from insatiable storage demand, stable pricing, and gains
   in market share.

Q. Which of the Fund's industries impaired results in 1997?

A. The weakest area in the portfolio was the networking industry. Numerous
   issues impacted this group in 1997:

   o  The 56 Kilobit (56K) modem standard was delayed into 1998, hurting overall
      modem sales. The Fund's investments in 3Com and Diamond Multimedia were
      therefore sold;

   o  Rapid advances in semiconductor technology reduced product prices,
      pressuring the revenue growth of many networking equipment vendors; and

   o  The networking industry's growth slowed from 30% two years ago to 15% in
      1997, reflecting maturing markets in the US and Europe, Asian weakness,
      and declining sales prices.

Q. What is your outlook on semiconductor capital equipment stocks?

A. The 1998 growth projections for worldwide semiconductor capital equipment
   spending fell from as high as 20% to zero or below in less than three months.
   In that period, the prices of chip equipment stocks fell as much as 50%.

      Nevertheless, we retained our positions for a number of reasons. First,
   most of the portfolio's investments in the sector are gaining market share,
   particularly against Japanese competitors. As a result, we expect the
   equipment companies held in the Fund to grow revenues by as much as 20% in
   1998 despite Asian spending cutbacks. Second, profit margins for the leading
   companies have been rising over time, reflecting increased competitive
   barriers for newcomers and fewer industry players. Finally, valuations are
   compelling, with most companies selling at low multiples of their earnings,
   book values, and sales.

Q. What is the state of the memory chip market and how will it affect the Fund?

A. In 1997, most memory chips, particularly DRAM circuits, experienced a second
   consecutive year of significant price declines. This drop played a major role
   in making personal

A TEAM APPROACH

Seligman Communications and Information Fund is managed by the Seligman
Technology Team, headed by Paul H. Wick. Mr. Wick and his team of seasoned
research professionals visit with the managements of hundreds of technology
companies each year to identify those that offer the greatest potential for
growth. Stocks purchased for the Fund are continually monitored by the Team,
and disciplined buy and sell policies are followed.

   computers (PCs) more affordable. For example, a PC buyer paid $400 for 16
   megabytes of memory in late 1995; today, 32 megabytes of DRAM cost
   approximately $60 in a typical PC. The DRAM industry has suffered from
   overcapacity for some time, and the recent Asian crisis magnified the problem
   as South Korean chip companies liquidated inventories to obtain US dollars.

      Additionally, within the past few months, the major South Korean DRAM
   suppliers -- Samsung, Hyundai, and LG Semicon -- all announced large cuts to
   their capital spending plans for 1998. We expect the leading Japanese DRAM
   companies to do the same. These actions will likely hinder the near-term
   results of the Fund's holdings in the semiconductor capital equipment
   industry. However, these spending cuts should help rehabilitate the global
   chip industry and should prove an overall positive for the industry's
   long-term health.

Q. How will the sub-$1,000 PC affect the technology sector?

A. The term "sub-$1,000 PC" usually refers to a PC without a monitor or
   speakers; when these and other features are added, prices typically rise to
   $1,100-$1,400. Nevertheless, there is clearly a trend toward lower-priced PCs
   for several reasons. First, virtually all PC components have rapidly declined
   in price, particularly DRAM chips, disk drives, microprocessors, and
   multimedia circuits. Second, greater market share concentration in the PC
   industry is an important factor, as larger PC companies like Compaq Computer
   and Dell Computer are translating discounts on high-volume component orders
   into lower prices for consumers. Finally, technology advances in hardware
   have recently overtaken the functional requirements of most software
   programs. As a result, consumers have become increasingly aware that they no
   longer need to invest in high-end PCs to have their computing needs met.

      While the trend towards cheaper PCs benefits consumers, it has created
   difficulties in the technology industry. Cheaper PCs generally are configured
   with smaller disk drives, less memory, and low-grade audio chips and
   microprocessors. This trend hurts component suppliers. In addition, PC
   resellers and retailers, and the PC companies themselves, garner far less
   revenue and profit per unit sold.

Q. What are some of the possible ramifications of the Asian financial crisis on
   US technology stocks?

A. The dramatic fall in value of Asian currencies relative to the US dollar,
   Japanese yen, and other "hard currencies" is likely to result in weakened
   global growth. In general, Asian demand for imported technology will be
   significantly reduced. This situation is exacerbated by the significant US
   dollar-denominated borrowings of many Asian companies, and the liquidity
   problems impacting the Asian banking sector. Additionally, the Asian crisis
   has negative implications for an already weak Japanese economy. Asia has
   historically been a critical export market for Japan, and Japanese banks have
   numerous questionable loans in the affected Asian countries.

      The sum of these problems is that US technology companies will have fewer
   export opportunities, and may have difficulty competing with Japanese
   products, which benefit from the weakened yen.

Q. Which areas within the technology sector appear strongest heading into 1998?

A. The Fund has increased its positions in the rapidly-growing industries most
   likely to be unscathed by the Asian crisis:

   o  Data storage companies are capitalizing on companies' increasing demands
      for fast access to "mission-critical" data like inventories and customer
      orders;

   o  Entertainment software companies are benefiting from the continued growth
      in the installed base of consumer PCs and videogame machines like the Sony
      Playstation;

   o  Information services and computer software companies have seen accelerated
      growth from their products addressing the "Year 2000" problem;

   o  Mechanical and integrated circuit design software firms have all benefited
      from consolidation in their industries; and

   o  Radio broadcasting companies continue to take advertising share from other
      media sectors.

Q. What are some of the necessary catalysts to reaccelerate the broad technology
   markets?

A. Obviously, currency stabilization and continued economic growth in Asia would
   be helpful to the world's technology industries. However, we believe new
   products are likely to play a major role in the next 12 months:

   o  Intel's new 440BX core logic chipset, due in April, significantly expands
      the performance of Pentium-II-based PCs, accelerating the industry's
      transition to the Pentium-II and perhaps reducing the rate of PC price
      declines;

   o  The shift in industry standards to 56K modems will soon be final,
      reversing the 1997 stall in the modem upgrade market;


                                                                           -----
                                                                               3

Interview With Your Portfolio Manager, Paul H. Wick

   o  Cable and Asynchronous Digital Subscriber Line (ADSL) modems will commence
      widespread deployment in 1998, offering Internet users even faster access
      to on-line information;

   o  Internet appliances, such as WebTV and Internet telephones, could achieve
      significant sales volume in 1998; and

   o  DVD players and high-definition televisions will likely become mass-market
      consumer items over the next two years.

Q. What is your overall outlook for the Fund?

A. As we go to press, the trend in earnings-estimate revisions for technology
   companies has been mostly downward in the past four months. At the same time,
   there is considerable uncertainty, given the turbulence in Asia. Undoubtedly,
   1998 will be challenging for technology investors.

      Nevertheless, we remain optimistic regarding the Fund's long-term
   appreciation potential and anticipate a more positive environment in the
   second half of 1998. Our reasoning is as follows:

   o  The prices of US technology stocks have already been discounted for a
      great deal of bad news, as reflected in their low absolute and relative
      valuations;

   o  Semiconductor capital spending cutbacks in South Korea and Japan will help
      restore the global chip industry's long-term health;

   o  New operating systems from Microsoft and chipsets from Intel will move the
      PC industry back toward high-performance machines with more memory and
      faster processors;

   o  Dramatic improvements in communications bandwidth, likely to be seen in
      late 1998 and early 1999, should spur accelerated development of the
      Internet and renewed growth for technology in general; and

   o  By mid-1998, investors should include 1999 earnings expectations in their
      valuations of technology companies.

Federal Tax Status of 1997 Gain Distribution for Taxable Accounts

   The distribution of $5.937 per share, consisting of $3.002 from net long-term
gain and $2.935 from net short-term gain, realized on investments from November
1996 to October 1997, was paid on November 21, 1997, to Class A, B, and D
shareholders. The federal Taxpayer Relief Act of 1997 modified the
classification of long-term capital gains to include a "28% Rate Gain" category.
Please note that 51% of the November 1997 long-term capital gain distribution is
categorized as "28% Rate Gain."

   The long-term gain distribution is designated a "capital gain dividend" for
federal income tax purposes and is taxable to shareholders in 1997 as a
long-term gain from the sale of capital assets, no matter how long you may have
owned your shares, or whether the distribution was received in shares or in
cash. However, if shares on which a capital gain distribution was received are
subsequently sold, and such shares have been held for six months or less from
the date of purchase, any loss on the sale would be treated as long-term to the
extent that it offsets the long-term gain distribution. The net short-term gain
is taxable as ordinary income whether paid to you in shares or in cash.

   If the distribution was received in shares, the per share cost basis for
federal income tax purposes is $24.41 for Class A shares, $23.07 and $23.05 for
Class B and D shares, respectively.

   A year-end statement of account showing activity for 1997, a Form 1099-DIV,
and if applicable, a Form 1099-B has been mailed to each shareholder. Form
1099-B shows the proceeds of any redemptions paid to the shareholder during the
year and reported to the Internal Revenue Service as required by federal
regulations. Form 1099-DIV shows the amount of the distribution from gain on
investments paid to the shareholder during the year.

   A fund that concentrates its investments in one economic sector may be
subject to greater share price fluctuations than a more diversified fund.

   The performances of Class B and D shares will be greater than or less than
the performance shown for Class A shares, based on the differences in sales
charges and fees paid by shareholders.

   The rates of return will vary and the principal value of an investment will
fluctuate. Shares, if redeemed, may be worth more or less than their original
cost. Past performance is not indicative of future investment results.

- ----------
   *  Returns for periods of less than one year are not annualized.
   ** Return figures reflect any change in price per share and assume the
      investment of capital gain distributions. Returns for Class A shares are
      calculated with and without the effect of the initial 4.75% maximum sales
      charge. Returns for Class A shares also reflect the effect of the service
      fee of up to 0.25% under the Administration, Shareholder Services and
      Distribution Plan after January 1, 1993, only. Returns for Class B shares
      are calculated with and without the effect of the maximum 5% contingent
      deferred sales load ("CDSL"), charged on redemptions made within one year
      of the date of purchase, declining to 1% in the sixth year and 0%
      thereafter. Returns for Class D shares are calculated with and without the
      effect of the 1% CDSL, charged on redemptions made within one year of the
      date of purchase.
  *** The Lipper Science & Technology Average is an average of 57 science and
      technology funds and excludes the effect of the sales charges that may be
      incurred in connection with purchases or sales. The monthly performance is
      used in the Performance Overview. The S&P 500 is an unmanaged index that
      assumes investment of dividends and excludes the effect of fees and sales
      charges. Investors cannot invest directly in an average or an index.
   +  The CDSL is 5% for periods of one year or less, and 4% since inception.
   ++ From April 30, 1996.
  +++ From April 30, 1993.
  (o) Represents the per share amount of net unrealized appreciation of
      portfolio securities as of December 31, 1997.

Notes to Financial Statements

1. Multiple Classes of Shares -- Seligman Communications and Information Fund,
Inc. (the "Fund") offers three classes of shares. All shares existing prior to
May 3, 1993, the commencement of Class D shares, were classified as Class A
shares. The Fund began offering Class B shares on April 22, 1996. Class A shares
are sold with an initial sales charge of up to 4.75% and a continuing service
fee of up to 0.25% on an annual basis. Class A shares purchased in an amount of
$1,000,000 or more are sold without an initial sales charge but are subject to a
contingent deferred sales load ("CDSL") of 1% on redemptions within 18 months of
purchase. Class B shares are sold without an initial sales charge but are
subject to a distribution fee of 0.75%, a service fee of up to 0.25% on an
annual basis, and a CDSL, if applicable, of 5% on redemptions in the first year
of purchase, declining to 1% in the sixth year and 0% thereafter. Class B shares
will automatically convert to Class A shares on the last day of the month that
precedes the eighth anniversary of their date of purchase. Class D shares are
sold without an initial sales charge but are subject to a distribution fee of up
to 0.75% and a service fee of up to 0.25% on an annual basis, and a CDSL, if
applicable, of 1% imposed on redemptions made within one year of purchase. The
three classes of shares represent interests in the same portfolio of
investments, have the same rights and are generally identical in all respects
except that each class bears its separate distribution and certain other class
expenses, and has exclusive voting rights with respect to any matter on which a
separate vote of any class is required.

2. Significant Accounting Policies -- The financial statements have been
prepared in conformity with generally accepted accounting principles which
require management to make certain estimates and assumptions at the date of the
financial statements. The following summarizes the significant accounting
policies of the Fund:

a.  Security Valuation -- Investments in convertible securities and common
    stocks are valued at current market values or, in their absence, at fair
    values determined in accordance with procedures approved by the Board of
    Directors. Securities traded on national exchanges are valued at last sales
    prices or, in their absence and in the case of over-the-counter securities,
    at the mean of bid and asked prices. Short-term holdings maturing in 60 days
    or less are valued at amortized cost.

b.  Federal Taxes -- There is no provision for federal income tax. The Fund has
    elected to be taxed as a regulated investment company and intends to
    distribute substantially all taxable net income and net gain realized.

c.  Security Transactions and Related Investment Income -- Investment
    transactions are recorded on trade dates. Identified cost of investments
    sold is used for both financial statement and federal income tax purposes.
    Dividends receivable and payable are recorded on ex-dividend dates. Interest
    income is recorded on an accrual basis.

d.  Multiple Class Allocations -- All income, expenses (other than
    class-specific expenses), and realized and unrealized gains or losses are
    allocated daily to each class of shares based upon the relative value of
    shares of each class. Class-specific expenses, which include distribution
    and service fees and any other items that are specifically attributable to a
    particular class, are charged directly to such class. For the year ended
    December 31, 1997, distribution and service fees were the only
    class-specific expenses.

e.  Distributions to Shareholders -- The treatment for financial statement
    purposes of distributions made to shareholders during the year from net
    investment income or net realized gains may differ from their ultimate
    treatment for federal income tax purposes. These differences are caused
    primarily by differences in the timing of the recognition of certain
    components of income, expense, or realized capital gain for federal income
    tax purposes. Where such differences are permanent in nature, they are
    reclassified in the components of net assets based on their ultimate
    characterization for federal income tax purposes. Any such reclassification
    will have no effect on net assets, results of operations, or net asset value
    per share of the Fund.

3. Purchases and Sales of Securities -- Purchases and sales of portfolio
securities, excluding US Government obligations and short-term investments, for
the year ended December 31, 1997, amounted to $6,650,931,325 and $6,334,624,528,
respectively.

    At December 31, 1997, the cost of investments for federal income tax
purposes was substantially the same as the cost for financial reporting
purposes, and the tax basis gross unrealized appreciation and depreciation of
portfolio securities amounted to $604,883,743 and $392,624,127, respectively.

4. Management Fee, Administrative Services, and Other Transactions -- J. & W.
Seligman & Co. Incorporated (the "Manager") manages the affairs of the Fund and
provides the necessary personnel and facilities. Compensation of all officers of
the Fund, all directors of the Fund who are employees or consultants of the
Manager, and all personnel of the Fund and the Manager is paid by the Manager.
The Manager receives a fee, calculated daily and payable monthly, equal to 0.90%
per annum of the first $3 billion of the Fund's average daily net assets, 0.85%
per annum of the next $3 billion of the Fund's average daily net assets and
0.75% per annum of the Fund's average daily net assets in excess of $6 billion.
The management fee reflected in the Statement of Operations represents 0.89% per
annum of the Fund's average daily net assets.

Notes to Financial Statements

    Seligman Financial Services, Inc. (the "Distributor"), agent for the
distribution of the Fund's shares and an affiliate of the Manager, received
concessions of $2,126,669 from sales of Class A shares, after commissions of
$17,264,591 were paid to dealers.

    The Fund has an Administration, Shareholder Services and Distribution Plan
(the "Plan") with respect to distribution of its shares. Under the Plan, with
respect to Class A shares, service organizations can enter into agreements with
the Distributor and receive a continuing fee of up to 0.25% on an annual basis,
payable quarterly, of the average daily net assets of the Class A shares
attributable to the particular service organizations for providing personal
services and/or the maintenance of shareholder accounts. The Distributor charges
such fees to the Fund pursuant to the Plan. For the year ended December 31,
1997, fees incurred aggregated $7,044,674, or 0.25% per annum of the average
daily net assets of Class A shares.

    Under the Plan, with respect to Class B and Class D shares, service
organizations can enter into agreements with the Distributor and receive a
continuing fee for providing personal services and/or the maintenance of
shareholder accounts of up to 0.25% on an annual basis of the average daily net
assets of the Class B and Class D shares for which the organizations are
responsible; and, for Class D shares only, fees for providing other distribution
assistance of up to 0.75% on an annual basis of such average daily net assets.
Such fees are paid monthly by the Fund to the Distributor pursuant to the Plan.

    With respect to Class B shares, a distribution fee of 0.75% on an annual
basis of average daily net assets is payable monthly by the Fund to the
Distributor; however, the Distributor has sold its rights to substantially all
of this fee to a third party (the "Purchaser"), which provides funding to the
Distributor to enable it to pay commissions to dealers at the time of the sale
of the related Class B shares.

    For the year ended December 31, 1997, fees incurred under the Plan,
equivalent to 1% per annum of the average daily net assets of Class B and Class
D shares, amounted to $2,784,474 and $8,713,305, respectively.

    The Distributor is entitled to retain any CDSL imposed on redemptions of
Class D shares occurring within one year of purchase and on certain redemptions
of Class A shares occurring within 18 months of purchase. For the year ended
December 31, 1997, such charges amounted to $266,694.

    The Distributor has sold its rights to collect any CDSL imposed on
redemptions of Class B shares to the Purchaser. In connection with the sale of
its rights to collect any CDSL and the distribution fees with respect to Class B
shares described above, the Distributor receives payments from the Purchaser
based on the value of Class B shares sold. The aggregate amount of such payments
and the Class B shares distribution fees retained by the Distributor, for the
year ended December 31, 1997, amounted to $1,048,230.

    Seligman Services, Inc., an affiliate of the Manager, is eligible to receive
commissions from certain sales of shares of the Fund, as well as distribution
and service fees pursuant to the Plan. For the year ended December 31, 1997,
Seligman Services, Inc. received commissions of $494,285 from the sales of
shares of the Fund. Seligman Services, Inc. also received distribution and
service fees of $961,731, pursuant to the Plan.

    Seligman Data Corp., which is owned by certain associated investment
companies, charged the Fund at cost $11,898,218 for shareholder account
services.

    Certain officers and directors of the Fund are officers or directors of the
Manager, the Distributor, Seligman Services, Inc., and/or Seligman Data Corp.

    The Fund has a compensation arrangement under which directors who receive
fees may elect to defer receiving such fees. Interest is accrued on the deferred
balances. The annual cost of such fees and interest is included in directors'
fees and expenses and the accumulated balance thereof at December 31, 1997,
of $114,234 is included in other liabilities. Deferred fees and the related
accrued interest are not deductible for federal income tax purposes until such
amounts are paid.

5. Committed Line of Credit -- Effective July 23, 1997, the Fund increased its
committed line of credit facility with a group of banks to $340 million from
$280 million. Borrowings pursuant to the credit facility are subject to interest
at a rate equal to the federal funds rate plus 0.50% per annum. The Fund incurs
a commitment fee of 0.10% per annum on the unused portion of the credit
facility. The credit facility may be drawn upon only for temporary purposes and
is subject to certain other customary restrictions. The credit facility
commitment expires one year from the date of the agreement but is renewable with
the consent of the participating banks. To date, the Fund has not borrowed from
the credit facility. 


                                                                           -----

6. Affiliated Issuers -- As defined under the Investment Company Act of 1940, as
amended, affiliated issuers are those in which the Fund's holdings of an issuer
represent 5% or more of the outstanding voting securities of the issuer. A
summary of the Fund's transactions in the securities of these issuers during the
year ended December 31, 1997, is as follows:

Financial Highlights

    The Fund's financial highlights are presented below. "Per share operating
performance" data is designed to allow investors to trace the operating
performance of each Class, on a per share basis, from the beginning net asset
value to the ending net asset value, so that investors can understand what
effect the individual items have on their investment, assuming it was held
throughout the period. Generally, per share amounts are derived by converting
the actual dollar amounts incurred for each item, as disclosed in the financial
statements, to their equivalent per share amounts.

    "Total return based on net asset value" measures each Class's performance
assuming that investors purchased Fund shares at net asset value as of the
beginning of the period, invested dividends and capital gains paid at net asset
value, and then sold their shares at the net asset value on the last day of the
period. The total return computations do not reflect any sales charges investors
may incur in purchasing or selling shares of the Fund. Total returns for periods
of less than one year are not annualized.

   "Average commission rate paid" represents the average commission paid by the
Fund to purchase or sell portfolio securities. It is determined by dividing the
total commission dollars paid by the number of shares purchased and sold during
the period for which commissions were paid. This rate is provided for periods
beginning January 1, 1996.

The Board of Directors and Shareholders,

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Seligman Communications and Information Fund,
Inc. as of December 31, 1997, the related statements of operations for the year

presented. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our

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 and financial

statements. Our procedures included confirmation of securities owned as of
December 31, 1997, by correspondence with the Fund's custodian and brokers;
where replies were not received from brokers, we performed other auditing
procedures. 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, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Seligman

Glossary of Financial Terms

CAPITAL GAIN DISTRIBUTION -- A payment to mutual fund shareholders of profits
realized on the sale of securities in the fund's portfolio. For tax purposes,
these profits may be taxed at different rates, primarily depending upon the
length of time the securities were owned by the fund.

CAPITAL APPRECIATION/DEPRECIATION -- An increase or decrease in the market value
of a mutual fund's portfolio securities, which is reflected in the net asset
value of the fund's shares. Capital appreciation/depreciation of an individual
security is in relation to the original purchase price.

COMPOUNDING -- The change in the value of an investment as shareholders receive
earnings on their investment's earnings. For example, if $1,000 is invested at a
fixed rate of 7% a year, the initial investment is worth $1,070 after one year.
If the return is compounded, second year earnings will not be based on the
original $1,000, but on the $1,070, which includes the first year's earnings.

CONTINGENT DEFERRED SALES LOAD (CDSL) -- Depending on the class of shares owned,
a fee charged by a mutual fund when shares are sold back to the fund (the CDSL
expires after a fixed time period).

DIVIDEND -- A payment by a mutual fund, usually derived from the fund's net
investment income (dividends and interest less expenses).

DIVIDEND YIELD -- A measurement of a fund's dividend as a percentage of the
maximum offering price.

EXPENSE RATIO -- The cost of doing business for a mutual fund, expressed as a
percent of the fund's net assets.

INVESTMENT OBJECTIVE -- The shared investment goal of a fund and its
shareholders.

MANAGEMENT FEE -- The amount paid by a mutual fund to its investment advisor(s).

MULTIPLE CLASSES OF SHARES -- Although an individual mutual fund invests in only
one portfolio of securities, it may offer investors several purchase options
which are "classes" of shares. Multiple classes permit shareholders to choose
the fee structure that best meets their needs and goals. Generally, each class
will differ in terms of how and when sales charges and certain fees are
assessed.

NATIONAL ASSOCIATION OF SECURITIES DEALERS, INC. (NASD) -- A self-regulatory
body with authority over firms that distribute mutual funds.

NET ASSET VALUE (NAV) PER SHARE -- The market worth of one fund share, obtained
by adding a mutual fund's total assets (securities, cash, and any accrued
earnings), subtracting liabilities, and dividing the resulting net assets by the
number of shares outstanding.

OFFERING PRICE (OP) -- The price at which a mutual fund's share can be
purchased. The offering price per share is the current net asset value plus any
sales charge.

PORTFOLIO TURNOVER -- A measure of the trading activity in a mutual fund's
investment portfolio that reflects how often securities are bought and sold.

PROSPECTUS -- The legal document describing a mutual fund to all prospective
shareholders. It contains information required by the Securities and Exchange
