             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 June 30, 2002, and the consolidated results of
     operations and cash flows for the periods presented herein. Results for the
     three and six months ended June 30, 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 June 30, 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.

E.   GOODWILL AND IDENTIFIED INTANGIBLE ASSETS

     Effective as of January 1, 2002, the Company adopted Statement of Financial
     Accounting Standards (SFAS) No. 142, GOODWILL AND OTHER INTANGIBLE ASSETS.
     Under SFAS No. 142, goodwill and intangible assets with indefinite lives
     are no longer amortized but are reviewed at least annually, or more
     frequently if impairment indicators arise.

     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.

                  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 AND SIX MONTHS ENDED JUNE 30, 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 fourteen strategic acquisitions, including eight 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. 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

THREE MONTHS ENDED JUNE 30, 2002 COMPARED TO THREE MONTHS ENDED JUNE 30, 2001

The Company reported net income of $3.1 million, or $0.14 per diluted common
share, for the second quarter of 2002 compared with $1.9 million, or $0.09 per
diluted common share, in the second quarter of 2001. Results for the second
quarter of 2001 include amortization of goodwill and certain other acquired
intangible assets of approximately $1.0 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 June 30, 2001 would have been $2.9 million, or
$0.14 per diluted common share, compared with $3.1 million, or $0.14 per diluted
common share, for the second quarter of 2002.

The overall increase in second quarter 2002 earnings over the prior year was due
primarily to increased gross profits in the Company's IP and STI segments,
including both a positive impact from businesses acquired in 2001 and growth in
core businesses, the impact of the accounting change pursuant to SFAS No. 142,
as well as a decrease in the Company's effective income tax rate. The positive
factors were partially offset by decreased earnings in the Company's ITL
segment, increased depreciation related to capital expenditures, increased
amortization of acquired intangible assets and lower interest income.

                            INFORMATION HOLDINGS INC.
                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

Net interest income (expense) decreased to $0.1 million from $0.9 million due
primarily to the use of cash from the secondary public stock offering to acquire
businesses during 2001 and 2002 (See Note D - ACQUISITIONS). Additionally, the
average interest rate decreased to 1.9% in the second quarter of 2002 from 4.5%
in the comparable prior year period.

The provision for income taxes as a percentage of pre-tax income for the three
months ended June 30, 2002 was 36.2%, compared to 40.3% for the second quarter
of 2001, due primarily to the adoption of SFAS No. 142, which eliminates
goodwill amortization, a significant amount of which was not tax-deductible.
Additionally, the Company was also subject to foreign taxes during the second
quarter of 2002 and 2001, which were immaterial in the periods.

SEGMENT REVIEW

INTELLECTUAL PROPERTY (IP)

IP revenue for the second quarter of 2002 increased 84.1%, or $8.9 million, to
$19.5 million compared to $10.6 million in the comparable period in 2001. The
increase in revenues includes $0.8 million from continued strong internal growth
in existing IP information and IP management businesses, $0.9 million of
revenues from Aurigin products acquired in 2002 and an increase of $7.2 million
in revenue at Liquent-IDRAC, primarily as a result of the acquisition of Liquent
in fiscal 2001. Operating income increased 111.1%, or $1.8 million, to $3.4
million for 2002, compared to $1.6 million of operating income in the prior year
quarter. The increase in operating income includes an increase of $1.0 million
at Liquent-IDRAC and an increase of $0.8 million in core IP information and IP
management businesses. IP cost of sales, expressed as a percentage of revenues,
increased from 27.5% to 30.2%, due primarily to the inclusion of Liquent in
fiscal 2002 results. Selling, general and administrative (S,G&A) expenses,
increased $3.8 million or 108.4%, due primarily to the expenses of Liquent and
Aurigin, businesses acquired in December 2001 and in May 2002, respectively.
Included in S,G&A expenses for the quarter ended June 30, 2002 is an unrealized
foreign exchange loss of $0.3 million, due primarily to the revaluation of U.S.
dollar denominated cash held by the Company's French subsidiary. IP depreciation
and amortization increased $0.3 million, or 10.8%, primarily as a result of the
amortization of intangible assets and depreciation of purchased equipment
related to the above acquisitions, partially offset by the impact of the
accounting change pursuant to SFAS No. 142.

SCIENTIFIC AND TECHNOLOGY INFORMATION (STI)

STI revenue for the second quarter of 2002 increased 34.3%, or $3.3 million, to
$12.9 million from $9.6 million in the comparable period in 2001. The revenue
increase includes an increase of $0.8 million in international reference product
sales at CRC Press and an increase of $2.0 million at Parthenon Press (acquired
in May 2001), including an increase of approximately $0.8 million in its medical
communication division. Operating income increased 176.1%, or $1.2 million, to
$1.9 million for 2002, compared to $0.7 million in the prior year quarter, due
primarily to contributions from increased revenues. STI cost of sales, expressed
as a percentage of revenues, increased from 28.9% to 35.0%, due primarily to
increased contributions from Parthenon Press, which has lower gross margins than
CRC Press. S,G&A expenses were relatively constant in the periods. STI
depreciation and amortization increased $0.2 million, or 35.1%, primarily as
result of depreciation on new software systems.

            FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Continued)

INFORMATION TECHNOLOGY LEARNING (ITL)

ITL revenue for the second quarter of 2002 decreased 35.7%, or $1.8 million, to
$3.3 million compared to $5.1 million in the comparable period in 2001. The
revenue decline is a result of continued difficult overall market conditions in
information technology and a lack of significant new certifications by major
software companies in recent months. Operating income in the second quarter of
2002 decreased 59.8%, or $0.5 million, to $0.4 million, compared to prior year
operating income of $0.9 million, as a result of the revenue decline. Cost of
sales, expressed as a percentage of revenues, was relatively constant in the
periods, while S,G&A expenses decreased by $0.4 million, or 18.5%, as a result
of cost reduction initiatives. ITL depreciation and amortization decreased by
50%, or $0.8 million, based on the impact of the accounting change pursuant to
SFAS No. 142.

SIX MONTHS ENDED JUNE 30, 2002 COMPARED TO SIX MONTHS ENDED JUNE 30, 2001

The Company reported net income of $5.9 million, or $0.27 per diluted common
share, for the first six months of 2002 compared with $4.9 million, or $0.23 per
diluted common share, in the first six months of 2001. Results for the first
half of 2001 include amortization of goodwill and certain other acquired
intangible assets of approximately $1.8 million, net of tax. Upon adoption of
SFAS No. 142, the Company ceased amortizing goodwill as well as certain other
acquired intangible assets. Excluding amortization of these items net income for
the six months ended June 30, 2001 would have been $6.7 million, or $0.31 per
diluted common share, compared with $5.9 million, or $0.27 per diluted common
share, for the first half of 2002.

The overall increase in earnings in the first six months of 2002 over the prior
year period was due primarily to increased gross profits in the Company's IP and
STI segments, including both a positive impact from businesses acquired in 2001
and growth in core businesses, and a decrease in the Company's effective income
tax rate. The positive factors were partially offset by decreased earnings in
the Company's ITL segment and lower interest income. Depreciation and
amortization was relatively constant in the periods with increases in
depreciation related to capital expenditures and amortization of acquired
intangible assets, offset by the effect of the adoption of SFAS No. 142.

Net interest income (expense) decreased to $0.3 million from $2.4 million due
primarily to the use of cash from the secondary public stock offering to acquire
businesses during 2001 and 2002 (See Note D - ACQUISITIONS). Additionally, the
average interest rate decreased to 1.9% in the first six months of 2002 from
5.0% in the comparable prior year period.

The provision for income taxes as a percentage of pre-tax income for the six
months ended June 30, 2002 was 36.1%, compared to 40.8% for the first six months
of 2001, due primarily to the adoption of SFAS No. 142, which eliminates
goodwill amortization, a significant amount of which was not tax-deductible.
Additionally, the Company was also subject to foreign taxes during the first
half of 2002 and 2001, which were immaterial in the period.

SEGMENT REVIEW

INTELLECTUAL PROPERTY (IP)

IP revenue for the first six months of 2002 increased 105.5%, or $19.7 million,
to $38.4 million compared to $18.7 million in the comparable period in 2001. The
increase in revenues includes $1.8 million from continued strong internal growth
in existing IP information and IP management businesses, $0.9 million of
revenues from Aurigin products acquired in 2002 and an increase of $17.0 million
in revenue at Liquent-IDRAC, primarily as a result of the acquisition of Liquent
in fiscal 2001. Operating income increased 207.7%, or $5.1 million, to $7.6
million for 2002, compared to $2.5 million of operating income in the prior year
period. The increase in operating income includes an increase of $2.8 million at
Liquent-IDRAC, an increase of $1.6 million in core IP information and IP
management businesses, and a decrease of operating expenses of $0.7 million at
LPS. IP cost of sales, expressed as a percentage of revenues, increased from
28.4% to 29.6%, due primarily to the inclusion of Liquent in fiscal 2002
results. SG&A expenses, excluding costs of Liquent, increased $0.6 million, or
9.2%, primarily as a result of expenses related to Aurigin and increases at
IDRAC (acquired in March 2001), partially offset by decreased spending levels in
the LPS Group. IP depreciation and amortization increased $1.2 million, or
27.2%, primarily as a result of the amortization of intangible assets and
depreciation of purchased equipment related to acquisitions, partially offset by
the impact of the accounting change pursuant to SFAS No. 142.

SCIENTIFIC AND TECHNOLOGY INFORMATION (STI)

STI revenue for the first six months of 2002 increased 28.7%, or $5.3 million,
to $23.9 million from $18.6 million in the comparable period in 2001. The
revenue increase includes an increase of $1.0 million in reference product sales
at CRC Press and an increase of $4.0 million at Parthenon Press, which was
acquired in May 2001. Operating income increased 61.8%, or $1.1 million, to $2.9
million for 2002, compared to $1.8 million in the prior year period, due
primarily to contributions from increased revenues. STI cost of sales, expressed
as a percentage of revenues, increased from 29.7% to 33.9%, due primarily to
increased contributions from Parthenon Press, which has lower gross margins than
CRC Press. S,G&A expenses increased $1.2 million, or 11.9%, due primarily to the
acquisition of Parthenon Press. STI depreciation and amortization increased $0.4
million, or 38.2%, primarily as result of amortization of Parthenon Press
intangible assets and depreciation on new software systems.

INFORMATION TECHNOLOGY LEARNING (ITL)

ITL revenue for the first six months of 2002 decreased 46.0%, or $5.7 million,
to $6.6 million compared to $12.3 million in the comparable period in 2001. The
revenue decline is a result of continued difficult overall market conditions in
information technology and a lack of significant new certifications by major
software companies in recent months. Operating income in the first half of 2002
decreased 87.2%, or $2.8 million, to $0.4 million, compared to prior year
operating income of $3.2 million, as a result of the revenue decline. Cost of
sales, expressed as a percentage of revenues, was relatively constant in the
periods, while S,G&A expenses decreased by $0.9 million, or 18.3%, as a result
of cost reduction initiatives. ITL depreciation and amortization decreased by
49.4%, or $1.6 million, based primarily on the impact of the accounting change
pursuant to SFAS No. 142.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
            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 June 30, 2002, proceeds of approximately $147 million have been
used from this offering to fund acquisitions in the Company's information and
publishing businesses. See Note D - ACQUISITIONS for details on fiscal 2002 and
2001 acquisitions. The remaining net proceeds will be used to finance future
acquisitions and for general corporate purposes. 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 June 30, 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 June 30, 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 $52.4 million at
June 30, 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 $(7.8) million at June 30, 2002 compared to a working capital deficit
of $(6.6) million at December 31, 2001. The Company receives patent annuity
payments and subscription payments in advance and is, therefore, expected to
maintain very low or negative working capital balances, excluding cash. Included
in current liabilities at June 30, 2002 are obligations related to patent
annuity payments and deferred revenue of approximately $41.1 million.

                                      -16-

                            INFORMATION HOLDINGS INC.

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

Cash generated from operating activities was $13.6 million for the six months
ended June 30, 2002, derived from net income of $5.9 million plus non-cash
charges of $9.4 million less a decrease in operating assets and liabilities of
$1.7 million. The overall decrease in operating assets and liabilities is
primarily due to the timing of and the increase in the number of patent annuity
payments, and an increase in income tax liabilities offset primarily by a
decrease in accrued expenses related to acquisition deal costs for Liquent.

Cash used in investing activities was $15.0 million for the six months ended
June 30, 2002 primarily due to acquisition costs for Aurigin of $14.0 million
(See Note D - ACQUISITIONS). Spending related to capital expenditures, including
pre-publication costs and capitalized software, was $4.2 million in the first
half of 2002. Excluding acquisitions of businesses, the Company's existing
operations are not capital intensive.

Cash generated from financing activities was $0.5 million for the six months
ended June 30, 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 June 30, 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 or agreements with respect to any prospective material
acquisitions. 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 six months of fiscal 2002.

FORWARD-LOOKING STATEMENTS

Certain statements in this report contain 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 June 30, 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 losses for the three and six months ended June 30, 2002
were $299,000 and $134,000, respectively.

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 June 30, 2002, the subsidiary of the Company had entered
into forward contracts to acquire various international currencies, all having
maturities of less than seven months, aggregating approximately $15,735,000.
Realized gains and losses relating to the forward contracts were immaterial for
the quarter ended June 30, 2002.

The Company does not use derivative financial instruments for trading purposes.
