             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

A.       BASIS OF PRESENTATION

         The consolidated balance sheet of Information Holdings Inc. (IHI, or
         the Company) at December 31, 1999 has been derived from IHI's Annual
         Report on Form 10-K for the year then ended. All other consolidated
         financial statements contained herein have been prepared by IHI and are
         unaudited. These consolidated financial statements should be read in
         conjunction with the consolidated financial statements for the year
         ended December 31, 1999 and the notes thereto contained in IHI's Annual
         Report on Form 10-K.

         The accompanying unaudited consolidated financial statements have been
         prepared in accordance with Rule 10-01 of Regulation S-X for interim
         financial statements required to be filed with the Securities and
         Exchange Commission and do not include all information and footnotes
         required by generally accepted accounting principles for complete
         financial statements. However, in the opinion of management, the
         accompanying unaudited consolidated financial statements contain all
         adjustments, consisting only of normal recurring adjustments, necessary
         to present fairly the consolidated financial position of IHI as of
         September 30, 2000, and the consolidated results of operations and cash
         flows for the periods presented herein. Results for the three and nine
         months ended September 30, 2000 are not necessarily indicative of the
         results to be expected for the full fiscal year.

B.       SHORT-TERM INVESTMENT

         At September 30, 2000, the Company held a short-term investment in
         commercial paper, which was classified as held-to-maturity. The
         investment has a maturity date within one year and is stated at its
         amortized cost.

C.       INVENTORIES

         Inventories are stated at the lower of cost (first-in, first-out
         method) or market. Inventories at September 30, 2000 and December 31,
         1999 consist solely of finished goods. The vast majority of inventories
         are books, which are reviewed periodically on a title-by-title basis
         for salability. The cost of inventory determined to be impaired is
         charged to income in the period of determination.

D.       PRE-PUBLICATION COSTS

         Certain expenses related to books, primarily comprised of design and
         other pre-production costs, are deferred and charged to expense over
         the estimated product life. These costs are primarily amortized over a
         four-year period following release of the applicable book, using an
         accelerated amortization method. During 2000 and 1999, the Company
         removed from its Balance Sheets fully amortized pre-publication costs
         with a cost of approximately $3,554,000 and $1,645,000, respectively.

E.       SECONDARY OFFERING

         On March 14, 2000, the Securities and Exchange Commission declared
         effective the Company's registration statement on Form S-3, pursuant to
         which the Company completed a public offering on March 20, 2000 of

         future acquisitions and for general corporate purposes.

         $19.125 per share.

G.       IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

         In June 2000, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards (SFAS) No. 138, "Accounting for
         Certain Derivative Instruments and Certain Hedging Activities". This
         standard amends SFAS No. 133. "Accounting for Derivative Instruments
         and Hedging Activities", and addresses a limited number of issues
         causing implementation difficulties. The adoption of SFAS No. 138 is
         not expected to have a material effect on the Company's consolidated
         financial position or results of operations.

J.       SUBSEQUENT EVENT

         On November 6, 2000, the Company acquired all of the assets of
         Transcender Corporation (Transcender) for cash consideration of
         approximately $60,000,000. Transcender is a leading provider of on-line
         IT certification products. Transcender develops content and related
         software distributed over the Internet and in other electronic media to
         information technology professionals seeking certification in numerous
         product areas and programming languages. The Company is currently in
         the process of obtaining an independent appraisal regarding the
         purchase price allocation and determination of the useful lives of the
         assets acquired.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS:

Three Months Ended September 30, 2000 Compared to
Three Months Ended September 30, 1999
-------------------------------------------------

REVENUES. In the third quarter of 2000, the Company had revenues of $18.2
million compared to revenues of $14.8 million in the third quarter of 1999, an
increase of $3.4 million or 22.4%. The increase in revenues for the third
quarter of 2000 was due to several factors including strong internal growth in
Internet-based sales of patent information and patent file histories at
MicroPatent of approximately $1.0 million. Revenues at Master Data Center, which
was acquired in August 1999, increased $1.4 million, reflective of a full
quarter of revenue for 2000, and book sales at CRC Press increased $0.6 million.
Overall book sales for the third quarter of 2000 were 8.0% higher than the prior
years' quarter and international sales continue to improve over earlier 2000
quarters.

COST OF SALES. Cost of sales increased $1.2 million or 31.9% to $5.0 million in
the third quarter of 2000 compared to $3.8 million in the corresponding quarter
in 1999. Cost of sales expressed as a percentage of revenues in the third
quarter of 2000 increased to 27.9% from 25.9% for the corresponding quarter of
1999. The increase in the costs of sales over the comparable period in 1999 is
primarily attributable to lower gross margins as a result of a change in sales
channel mix at CRC Press. These increases were partially offset by improved
margins in the intellectual property businesses.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (SG&A). S,G&A expenses increased
$2.8 million or 38.9% in the third quarter of 2000, to $10.0 million from $7.2
million in the third quarter of 1999. Increased S,G&A expenses relate primarily
to operating expenses of businesses acquired in the third quarter of 1999 and
development spending on CorporateIntelligence.com. S,G&A expenses as a
percentage of revenues excluding development spending on
CorporateIntelligence.com decreased to 43.7% in the third quarter of 2000,
compared to 48.6% in the corresponding 1999 quarter. The improvement in margins
is a direct result of increased efficiency levels achieved in both newly
acquired and in existing businesses.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization in the third
quarter of 2000 increased $0.4 million, or 26.6%, to $2.1 million from $1.7
million in the corresponding quarter in 1999, primarily as a result of the
amortization of intangible assets of businesses acquired in the last half of
fiscal 1999 and increased depreciation due to capital expenditures purchased in
fiscal 2000.

INTEREST INCOME (EXPENSE). Interest income (expense) increased to $2.4 million
from $0.2 million due primarily to interest earned on the proceeds from the
secondary public stock offering completed in March 2000.

INCOME TAXES. The provision for income taxes as a percentage of pre-tax income
for the three months ended September 30, 2000 is 42.1%, which differs from the
statutory rate primarily as a result of state and local income taxes and
non-deductible amortization in excess of the purchase price over net assets
acquired. This compares with an effective tax rate of 44.5% in the prior year.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

Nine Months Ended September 30, 2000 Compared to
Nine Months Ended September 30, 1999
-------------------------------------------------

REVENUES. In the first nine months of 2000, the Company had revenues of $50.4
million compared to revenues of $39.9 million in the first nine months of 1999,
an increase of $10.5 million or 26.5%. The increase in revenues is primarily due
to an increase in Internet-based sales of patent information of approximately
$3.0 million at MicroPatent and an increase of $1.8 million in sales of patent
file histories at Optipat and Faxpat, businesses acquired in fiscal 1999.
Revenues at Master Data Center, which was acquired in August 1999, increased
$6.3 million, reflective of a full nine months of revenue for the period ended
September 30, 2000. These increases were partially offset by a decline of $0.8
million in international book sales at CRC Press. The Company previously
terminated an international distribution agreement in January 2000, and was
contractually restricted from selling many of its scientific information
products internationally for a 45-day period. International book sales increased
from previous quarter levels and further improvements are expected to continue
in the fourth quarter of 2000.

COST OF SALES. Cost of sales increased $3.6 million or 34.3% to $14.2 million in
the nine months of 2000 compared to $10.6 million in the corresponding period in
1999. Cost of sales expressed as a percentage of revenues in the first nine
months of 2000 increased to 28.2% from 26.6% for the corresponding period of
1999. The increase in the cost of sales percentage over the comparable period in
1999 is primarily attributable to the acquisition of MDC, which has historically
lower gross margins than the Company's other existing units. Gross margins for
the intellectual property businesses including MDC continued to improve over
previous periods as a result of the successful integration of acquired
businesses.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (SG&A). S,G&A expenses increased
$3.9 million or 18.7% in the first nine months of 2000, to $24.8 million from
$20.9 million for the first nine months of 1999. Increased S,G&A expenses relate
primarily to operating expenses of businesses acquired in the third quarter of
1999 and development spending on CorporateIntelligence.com, partly offset by a
decline in selling costs and improved efficiency levels in marketing and
production at CRC Press. S,G&A expenses as a percentage of revenues excluding
development spending on CorporateIntelligence.com decreased to 42.9% in the
first nine months of 2000, compared with 52.4% in the corresponding 1999 period.
The improvement in margins is a direct result of increased efficiency levels
achieved in both newly acquired and in existing businesses.

DEPRECIATION AND AMORTIZATION. Depreciation and amortization for the first nine
months of 2000 increased $2.8 million, or 75.6%, to $6.5 million from $3.7
million in the corresponding period in 1999, primarily as a result of the
amortization of intangible assets of businesses acquired in the last half of
fiscal 1999.

INTEREST INCOME (EXPENSE). Interest income (expense) increased to $5.0 million
from $1.3 million due primarily to interest earned on the proceeds from the
secondary public stock offering completed in March 2000.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

INCOME TAXES. The provision for income taxes as a percentage of pre-tax income
for the nine months ended September 30, 2000 is 42.3%, which differs from the
statutory rate primarily as a result of state and local income taxes and
non-deductible amortization in excess of the purchase price over net assets
acquired. This compares with an effective tax rate of 41.1% in the prior year.

LIQUIDITY AND CAPITAL RESOURCES:

In the first quarter of 2000, the Company sold 4,500,000 shares of its common
stock in a public offering and received approximately $155.0 million of net
proceeds. The proceeds from this offering will be used for the development and
marketing of the CorporateIntelligence.com website, to finance future
acquisitions, and for general corporate purposes. See Note J - SUBSEQUENT EVENT.
Pending such uses, the remaining net proceeds will be invested in short-term,
investment grade securities.

On September 24, 1999, the Company entered into a seven-year revolving credit
facility in an amount not to exceed $50,000,000 initially, including a
$10,000,000 sublimit for the issuance of standby letters of credit (the Credit
Facility). The proceeds from the Credit Facility are intended to be used to fund
acquisitions, to meet short-term working capital needs and for general corporate
purposes.

Borrowings under the Credit Facility bear interest at either the higher of the
bank's prime rate and one-half of 1% in excess of the overnight federal funds
rate plus a margin of 0.50% to 1.25%, or the Eurodollar Rate plus a margin of
1.5% to 2.25%, depending on the Company's ratio of indebtedness to earnings
before interest, taxes, depreciation and amortization. The Company also pays a
commitment fee of 0.375% on the unused portion of the Credit Facility. As of
September 30, 2000, the Company had no outstanding borrowings under the Credit
Facility.

Under the terms of the Credit Facility, the Company is required to maintain
certain financial ratios related to fixed charge coverage, leverage and interest
coverage, in addition to certain other covenants. As of September 30, 2000, the
Company was in compliance with all covenants.

Cash and cash equivalents including short-term investments totaled $162.3
million at September 30, 2000 compared to $7.6 million at December 31, 1999.
Excluding cash, cash equivalents, and short-term investments the Company had
working capital of $2.6 million at September 30, 2000 compared to a working
capital deficit of $(3.3) million at December 31, 1999. Since the Company
receives patent annuity payments and subscription payments in advance, the
Company's existing operations are expected to maintain very low or negative
working capital balances, excluding cash. Included in current liabilities at
September 30, 2000 are obligations related to patent annuity payments and
deferred subscription revenue of approximately $20.3 million.

Cash generated by operating activities was $7.4 million for the nine months
ended September 30, 2000, derived from net income of $5.7 million plus non-cash
charges of $7.7 million less an increase in operating assets, net of liabilities
of $6.0 million. This increase in net operating assets is primarily the result
of an increase in customer receivables resulting from strong third quarter sales
and the payment of expenses related to book publishing operations in
anticipation of fourth quarter sales.

                            INFORMATION HOLDINGS INC.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

Cash used in investing activities was $16.2 million for the nine months ended
September 30, 2000 due to capital expenditures, including pre-publication costs
of $4.2 million and acquisition costs of $5.1 million. Excluding acquisitions of
businesses and titles, the Company's existing operations are not capital
intensive. Capital expenditures for fiscal 2000 include approximately $1.1
million of non-recurring purchases of new computer equipment necessary to
facilitate the Company's increased Internet capacity. Additionally, the Company
invested $6.9 million in a short-term investment in commercial paper, which is
scheduled to mature in January 2001.

Cash generated from financing activities was $156.6 million for the nine months
ended September 30, 2000, and primarily related to net cash proceeds received
from the issuance of common stock as a result of the Company's secondary common
stock offering of 4,500,000 shares at a price of $36.50 per share. See Note E -
SECONDARY OFFERING. The Company has no outstanding debt obligations as of
September 30, 2000 related to the new Credit Facility.

The Company believes that funds generated from operations, together with cash on
hand and borrowings available under its Credit Facility will be sufficient to
fund the cash requirements of its existing operations for the foreseeable
future. The Company currently has no commitments for material capital
expenditures. For the year 2000, the Company expects to incur expenditures
aggregating $6.0 million in connection with the rollout of
CorporateIntelligence.com. Actual expenditures may vary depending on the timing
of the commercial rollout, the development and integration of the databases, the
hiring of additional technical staff and market acceptance of this web site, as
well as other factors. As of September 30, 2000 the Company has incurred $3.3
million of costs related to CorporateIntelligence.com. Future operating
requirements and capital needs may be subject to economic conditions and other
factors, many of which are beyond the Company's control.

SEASONALITY

The Company's business is somewhat seasonal, with revenues typically reaching
slightly higher levels during the third and fourth quarters of each calendar
year, based on historical publication schedules. In 1999, 32% of the Company's
revenues were generated during the fourth quarter with the first, second and
third quarters accounting for 21%, 22% and 25% of revenues, respectively. In
addition, the Company may experience fluctuation in revenues from period to
period based on the timing of acquisitions and new product launches.

EFFECTS OF INFLATION

The Company believes that inflation has not had a material impact on the results
of operations presented herein.

FORWARD-LOOKING STATEMENTS

The information above contains forward-looking statements, including, without
limitation, statements relating to the Company's plans, strategies, objectives,
expectations, and intentions that are made pursuant to the "safe harbor"
provisions of the Private Securities Litigation Reform Act of 1995. Readers are
cautioned that forward-looking statements contained in this Form 10-Q should be
read in conjunction with the Company's disclosures under the heading IMPORTANT
FACTORS RELATING TO FORWARD-LOOKING STATEMENTS contained in the Company's 1999
Annual Report on Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company has only limited involvement with derivative financial instruments
and does not use them for trading purposes.

The Company may be subject to market risks arising from changes in interest
rates. Interest rate exposure results from changes in the Eurodollar or the
prime rate, which are used to determine the interest rate applicable to
borrowings under the Credit Facility. As of September 30, 2000, the Company had
no outstanding borrowings under the Credit Facility.

The Company routinely enters into forward contracts to acquire various
international currencies in an effort to hedge foreign currency transaction
exposures of its operations. At September 30, 2000, the Company had entered into
forward contracts, all having maturities of less than three months, to acquire
various international currencies, aggregating $9,571,000. Realized gains and
losses relating to the forward contracts were immaterial for the three and nine
months ended September 30, 2000.
