             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, 2001 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, 2001
     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 the instructions to Form 10-Q 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 March 31, 2002, and the consolidated results of
     operations and cash flows for the periods presented herein. Results for the
     three months ended March 31, 2002 are not necessarily indicative of the
     results to be expected for the full fiscal year.

     Certain reclassifications have been made to the financial statements of the
     prior period to conform to the March 31, 2002 presentation.

B.   INVENTORIES

     Inventories, consisting primarily of finished goods, are stated at the
     lower of cost (first-in, first-out method) or market. Shipping costs, which
     consist of transportation costs associated with the delivery of the
     Company's products to customers, and handling costs are included in Cost of
     sales. The vast majority of inventories are books, which are reviewed
     monthly 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.

C.   IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARD

     In August 2001, the Financial Accounting Standards Board (FASB) issued
     Statement of Financial Accounting Standards (SFAS) No. 144, ACCOUNTING FOR
     THE IMPAIRMENT OR DISPOSAL OF LONG-LIVED ASSETS, which addresses financial
     accounting and reporting for the impairment or disposal of long-lived
     assets and supersedes SFAS No. 121, ACCOUNTING FOR THE IMPAIRMENT OF
     LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF, and the
     accounting and reporting provisions of APB No. 30, REPORTING THE RESULTS OF
     OPERATIONS FOR A DISPOSAL OF A SEGMENT OF A BUSINESS. SFAS No. 144 is
     effective for fiscal years beginning after December 15, 2002. The Company
     adopted SFAS No. 144 as of January 1, 2002. The adoption of SFAS No. 144
     did not have a significant impact on the consolidated financial position,
     results of operations, or cash flows of the Company.

F.   GOODWILL AND IDENTIFIED INTANGIBLE ASSETS

     In June 2001, the FASB issued SFAS No. 142, GOODWILL AND OTHER INTANGIBLE
     ASSETS, which requires the use of a non-amortization approach to account
     for purchased goodwill and intangible assets with indefinite lives. The
     Company was required to adopt SFAS No. 142 for acquisitions completed prior
     to July 1, 2001 on January 1, 2002. Effective January 1, 2002, goodwill and
     intangible assets with indefinite lives are no longer amortized but are
     reviewed at least annually for impairment.

     During the year ended December 31, 2001, the Company began the required
     transitional impairment review of goodwill and intangible assets with
     indefinite lives. This review required the Company to estimate the fair
     value of its identified reporting units as of December 31, 2001. For each
     of the reporting units, the estimated fair value was determined utilizing
     the expected present value of the future cash flows of the units. In all
     instances, the estimated fair value of the reporting units exceeded their
     respective book values and therefore no write-down of goodwill or
     intangible assets with indefinite lives was required as of January 1, 2002.
     In addition, as of January 1, 2002, the Company ceased the amortization of
     goodwill and intangible assets with indefinite lives and reclassified the
     December 31, 2001 carrying value of its assembled workforce acquired
     intangible assets included in other identified intangibles to goodwill.

     The following unaudited reconciliation presents pro forma net income, basic
     and diluted EPS as if SFAS No. 142 had been adopted on January 1, 2001, is

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

THE FOLLOWING DISCUSSION AND ANALYSIS PRESENTS A REVIEW OF THE COMPANY FOR THE
THREE MONTHS ENDED MARCH 31, 2002 AND 2001. THIS REVIEW SHOULD BE READ IN
CONJUNCTION WITH THE CONSOLIDATED FINANCIAL STATEMENTS AND NOTES PRESENTED
HEREIN AS WELL AS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS CONTAINED IN THE COMPANY'S 2001 ANNUAL REPORT ON
FORM 10-K.

OVERVIEW

Impact of Acquisitions and Outlook

A key component of the Company's growth strategy is to pursue acquisitions in
attractive niche markets where opportunities exist to internally grow the
acquired companies' revenues and increase profitability through operating
efficiencies. Since beginning operations in January 1997, the Company has
completed thirteen strategic acquisitions, including seven in the
intellectual property area, five in scientific and technology information and
one in the information technology learning market, as well as some minor
acquisitions. The Company continues to actively seek acquisitions that will
further the Company's growth and operating strategies (See Note I -
SUBSEQUENT EVENTS). As the Company acquires additional companies, its sales
mix, market focus, cost structure and operating leverage may change
significantly. Consequently, the Company's historical and future results of
operations reflect and will reflect the impact of acquisitions from the date
of acquisition, and period-to-period comparisons may not be meaningful in
some respects. Historical information for companies subsequent to their
acquisition may include integration and other costs that are not expected to
continue in the future.

Consolidated Results of Operations

The Company reported net income of $2.8 million, or $0.13 per diluted common
share for the first quarter of 2002 compared with $3.0 million, or $0.14 per
diluted common share in the first quarter of 2001. Results for the first quarter
of 2001 also include amortization of goodwill and certain other acquired
intangible assets of approximately $0.7 million, net of tax. Upon adoption of
Statement of Financial Accounting Standard (SFAS) No. 142, GOODWILL AND OTHER
INTANGIBLE ASSETS, the Company ceased amortizing goodwill as well as certain
other acquired intangible assets. Excluding amortization of these items net
income for the three months ended March 31, 2001 would have been $3.7 million,
or $0.17 per diluted common share compared with $2.8 million, or $0.13 per
diluted common share for the first quarter of 2002.

The overall decrease in first quarter 2002 earnings over the prior year was
primarily due to a decrease in gross profit, the result of lower profit
contribution by the IT learning segment, which has higher gross margins than
the Company's other segments and decreased interest income, offset by strong
contributions from businesses acquired in 2001 and earnings growth in core IP
and STI businesses.

Net interest income (expense) decreased to $0.1 million from $1.5 million due
primarily to the use of cash from the secondary public stock offering to acquire
businesses during fiscal 2001 (See Note E - ACQUISITIONS). Additionally, the
average interest rate decreased from 5.6% in the first three months of 2001 to
2.0% in the comparable period in fiscal 2002.

                            INFORMATION HOLDINGS INC.

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

The provision for income taxes as a percentage of pre-tax income for the three
months ended March 31, 2002 is 35.9%, as compared to 41.1% for the first quarter
of 2001, due primarily to the adoption of SFAS No. 142, which eliminates
goodwill amortization, the majority of which was not tax-deductible.
Additionally, the Company was also subject to foreign taxes during the first
quarter of 2002, which were immaterial in the period.

SEGMENT REVIEW

INTELLECTUAL PROPERTY (IP) IP revenue for the first three months of 2002
increased 133.4%, or $10.8 million, to $18.9 million compared to $8.1 million
in the comparable period in 2001. Operating income increased 395% to $4.2
million for 2002, compared to $0.8 million of operating income in the prior
year quarter. Liquent and IDRAC contributed operating income of $1.8 million
in the first quarter of 2002. The increase in revenues includes $1.0 million
from continued strong internal growth in existing IP information and IP
management businesses and $9.8 million in revenue as a result of the
acquisitions of IDRAC and Liquent in fiscal 2001. IP cost of sales, expressed
as a percentage of revenues, remained constant in the periods. Selling,
general and administrative (S,G & A) expenses, excluding the results of the
acquisitions of IDRAC and Liquent decreased $0.7 million, or 21.8%, as a
result of a reduction in development spending in the LPS group from prior
year levels. IP depreciation and amortization increased $0.9 million, or 51%,
primarily as a result of the amortization of intangible assets and
depreciation of purchased equipment related to the above acquisitions, as
well as depreciation related to capital expenditures in fiscal 2001 in the
core businesses. The impact of the accounting change pursuant to SFAS No. 142
on this segment in the first three months of 2002 was a reduction in
amortization expense of $0.7 million.

SCIENTIFIC AND TECHNOLOGY INFORMATION (STI) STI revenue for the first three
months of 2002 increased 22.7%, or $2.0 million, to $11.0 million from $9.0
million in the comparable period in 2001. Operating income decreased 5.8%, or
$0.1 million, to $1.0 million for 2002, compared to $1.1 million in the prior
year quarter. STI operating results for 2002 include the acquisition of
Parthenon in May of 2001, which has lower gross margins than the existing
core STI business. Total expenses, excluding the acquisition of Parthenon,
increased $0.4 million, or 5.9% over the prior year quarter, primarily due to
increased costs in book publishing operations and an overall increase in
employee benefit costs. The increase in costs also includes the amortization
of capital expenditures in fiscal 2001 for capitalized software and purchased
equipment. The impact of the accounting change pursuant to SFAS No. 142 on
this segment in the first three months of 2002 was a reduction in
amortization expense of $0.1 million.

INFORMATION TECHNOLOGY LEARNING (ITL) ITL revenue for the first three months
of 2002 decreased 53.5%, or $3.8 million, to $3.3 million compared to $7.1
million in the comparable period in 2001. Operating income was slightly
better than breakeven for 2002, a decrease of 97.8% compared to the prior
year operating income of $2.3 million. The revenue fluctuation is a result of
very strong first quarter 2001 sales of Transcender's Windows 2000
certification products, a significant decline in the overall IT market since
the first quarter of 2001 and a lack of significant new certifications by
major software companies in recent months. Revenues in future quarters are
expected to improve with the anticipated release of new products. Cost of
sales, expressed as a percentage of revenues, remained constant in the
periods, while S,G & A expenses decreased by $0.5 million, or 18.1%, as a
result of cost reduction initiatives. The impact of the accounting change
pursuant to SFAS No. 142 on this segment in the first three months of 2002
was a reduction in amortization expense of $0.8 million.

            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

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 million of net
proceeds. As of March 31, 2002, proceeds of approximately $133 million have been
used from this offering to fund acquisitions in the Company's information and
publishing businesses. No acquisitions were made in the first quarter of 2002.
(See Note E - ACQUISITIONS for details on fiscal 2001 acquisitions). The
remaining net proceeds will be used to finance future acquisitions and for
general corporate purposes (See Note I - SUBSEQUENT EVENTS). Except as noted
above, the Company currently does not have any other agreements, arrangements or
understandings with respect to any prospective material acquisitions. Pending
such uses, the 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 sub-limit for the issuance of standby letters of credit (the Credit
Facility). Total commitments under the Credit Facility shall be permanently
reduced to $45,000,000 at the end of the third year, $37,500,000 at the end of
the fourth year, $25,000,000 at the end of the fifth year and $12,500,000 at the
end of the sixth year. The proceeds from the Credit Facility are 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 and
for the quarter ended March 31, 2002, 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 March 31, 2002, the
Company was in compliance with all covenants. The Credit Facility is secured by
a first priority perfected pledge of all notes and capital stock owned by the
Company's subsidiaries and a first priority perfected security interest in all
other assets of the Company and its subsidiaries, subject to certain exceptions.
Obligations under the Credit Facility will be guaranteed by the Company and its
subsidiaries. The Credit Facility also prohibits the Company from incurring
certain additional indebtedness, limits certain investments, mergers or
consolidations and restricts substantial asset sales, and dividends.

Cash and equivalents, including short-term investments, totaled $58.8 million
at March 31, 2002, compared to $56.4 million at December 31, 2001. Excluding
cash, cash equivalents and short-term investments, the Company had a working
capital deficit of $(4.0) million at March 31, 2002 compared to working
capital deficit of $(6.6) million at December 31, 2001. 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
March 31, 2002 are obligations related to patent annuity payments and
deferred revenue of approximately $41.7 million.

                                      -14-

                            INFORMATION HOLDINGS INC.

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

Cash generated from operating activities was $4.1 million for the three
months ended March 31, 2002, derived from net income of $2.8 million plus
non-cash charges of $4.6 million less a decrease in operating assets and
liabilities of $3.3 million. The overall decrease in operating assets and
liabilities is primarily the result of an increase in customer receivables
and deferred revenue at Liquent, a business acquired in December 2001 that
had strong first quarter 2002 results, and an increase in income tax
liabilities offset primarily by a decrease in accrued expenses related to
acquisition deal costs for Liquent.

Cash generated from investing activities was $1.6 million for the quarter
ended March 31, 2002, as a result of the Company liquidating $3.4 million in
short-term investments in commercial paper upon their maturity in the first
quarter of 2002 in anticipation of an acquisition in the second quarter (See
Note I -SUBSEQUENT EVENTS). Spending related to capital expenditures,
including pre-publication costs and internally developed software, was $1.8
million in the quarter. Excluding acquisitions of businesses, the Company's
existing operations are not capital intensive. Capital expenditures for
fiscal 2002 include approximately $0.5 million of purchases of new computer
equipment necessary to facilitate the Company's increased Internet capacity.

Cash generated from financing activities was $0.2 million for the three months
ended March 31, 2002, primarily due to net cash proceeds received from the
issuance of common stock from stock option exercises. The Company has no
outstanding debt obligations as of March 31, 2002 related to the 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. The Company may choose to obtain additional capital or financing
to consummate future acquisitions. 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 publication schedules and other factors. In 2001, 28% of the
Company's revenues were generated during the fourth quarter with the first,
second and third quarters accounting for 23%, 24% and 25% of revenues,
respectively. In addition, the Company may experience fluctuations 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.

CRITICAL ACCOUNTING POLICIES

The Company's accounting policies are disclosed in the Company's 2001 Annual
Report on Form 10-K. There have been no material changes to these policies
during the first three months of fiscal 2002.

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 2001
Annual Report on Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

INTEREST RATE RISK - 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 March 31, 2002, the
Company had no outstanding borrowings under the Credit Facility.

FOREIGN CURRENCY EXCHANGE RATE RISK - The financial statements of the Company's
foreign subsidiaries are translated from the local currency into U.S. dollars.
Assets and liabilities are translated using current exchange rates, except
certain accounts of subsidiaries whose functional currency is the U.S. dollar,
and translation adjustments are accumulated in a separate component of
stockholders' equity. Revenue and expenses are translated at average monthly
exchange rates, and translation adjustments are charged and credited to income.
As such, the Company's operating results are affected by fluctuations in the
value of the U.S. dollar compared to the British pound and the Euro. Foreign
exchange translation gains or losses were not material in any of the periods
presented.

A subsidiary of the Company routinely enters into forward contracts to acquire
various international currencies in an effort to hedge foreign currency
transaction exposures of its operations. Such forward contracts have been
designated as hedges for future annual patent payments to related international
regulatory agencies. At March 31, 2002, the subsidiary of the Company had
entered into forward contracts to acquire various international currencies, all
having maturities of less than five months, aggregating approximately
$16,488,000. Realized gains and losses relating to the forward contracts were
immaterial for the quarter ended March 31, 2002.

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