INDEPENDENT AUDITORS' REPORT
The Board of Directors
Seligman Communications and Information Fund, Inc.
In planning and performing our audit of the financial statements of Seligman
Communication and Information Fund, Inc. (the "Fund") for the year ended
December 31, 1998 (on which we have issued our report dated February 5, 1999),
we considered its internal control, including control activities for
safeguarding securities, in order to determine our auditing procedures for the
purpose of expressing our opinion on the financial statements and to comply with
the requirements of Form N-SAR, and not to provide assurance on the Fund's
internal control.
The management of the Fund is responsible for establishing and maintaining
internal control. In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and related costs of
controls. Generally, controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements for external purposes that
are fairly presented in conformity with generally accepted accounting
principles. Those controls include the safeguarding of assets against
unauthorized acquisition, use, or disposition.
Because of inherent limitations any internal control, misstatements due to error
or fraud may occur and not be detected. Also, projections of any evaluation of
internal control to future periods are subject to the risk that the internal
control may be become inadequate because of changes in conditions, or that the
degree of compliance with policies and procedures may deteriorate.
Our consideration of the Fund's internal control would not necessarily disclose
all matters in the internal control that might be material weaknesses under
standards established by the American Institute of Certified Public Accountants.
A material weakness is a condition in which the design or operation of one or
more of the internal control components does not reduce to a relatively low
level the risk that misstatements caused by error or fraud in amounts that would
be material in relation to the financial statements being audited may occur and
not be detected within a timely period by employees in the normal course of
performing their assigned functions. However, we noted no matters involving the
Fund's internal control and its operation, including controls for safeguarding
securities, that we consider to be material weaknesses as defined above as of
December 31, 1998.
This report is intended solely for the information and use of management, the
Board of Directors of Seligman Communication and Information Fund, Inc., and the
Securities and Exchange Commission and is not intended to be and should not be
used by anyone other than these specified parties.
