NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Three and Nine Months Ended June 30, 2000 and 1999 and as of June 30, 2000 and
September 30, 1999





The accompanying interim consolidated financial statements for the three and nine months ended
June 30, 2000 and 1999, and as of June 30, 2000 are unaudited, but have been prepared in accordance
with generally accepted accounting principles for interim consolidated financial statements. Certain
information or footnote disclosure normally included in annual financial statements prepared in
accordance with generally accepted accounting principles has been condensed or omitted in accordance
with guidance for interim financial statements. In the opinion of management, all adjustments
(consisting only of normal recurring adjustments) considered necessary for a fair presentation have
been included.  The results of operations of any interim period are not necessarily indicative of
the results of the operations for the full year.  These consolidated financial statements should be
read in conjunction with the audited, consolidated financial statements as of and for the year ended
September 30, 1999, and the related notes thereto, included in the Company's Form 10-K filed with
the SEC.

Organization and Description of Business-IDG Books Worldwide, Inc. (the "Company"), a
Massachusetts company, was founded in 1990 as a wholly-owned subsidiary (through intermediate
companies) of International Data Group, Inc. (the "Parent"). On March 24, 1998, the Company was
reincorporated in Delaware.

The Company is a leading global knowledge company featuring a diverse
portfolio of technology, consumer, and general how-to book brands, computer-based learning tools,
Web sites and Internet e-services. The Company publishes and markets under well-known brand names,
including

Principles of Consolidation-The consolidated financial statements include the accounts of
IDG Books Worldwide, Inc. and its majority controlled subsidiaries (collectively referred to as the
Company). All significant intercompany accounts and transactions have been eliminated.

Reclassifications-Certain amounts in prior years' financial statements and related notes
have been reclassified to conform to the fiscal year 2000 presentation. The accompanying
consolidated balance sheet as of June 30, 2000 reports a deferred tax liability of approximately $5.0
million with a corresponding addition to goodwill to reflect the book/tax difference related to the
carrying value of Cliff's Notes intangible assets. The accompanying consolidated balance sheet as of
September 30, 1999 has been reclassified to conform to this presentation.



Fiscal Year-The Company's fiscal year ends on the last Saturday of each September. Fiscal
year 1999, ended on September 25, 1999, and consisted of 52 weeks. For convenience, fiscal year-ends
are denoted in the accompanying consolidated financial statements as September 30. Similarly, the
thirteen- and thirty-nine-week periods ended June 24, 2000 and June 26, 1999 are referred to as the
three and nine months ended June 30, 2000 and 1999, respectively.

Intangible Assets-Intangible assets represent trademarked brand names, goodwill,
publishing rights and other intangible assets. Amortization is provided on a straight-line method
over the estimated useful lives of these assets not exceeding forty years.

Net Income Per Share-Basic net income per share excludes dilution and is computed using
the weighted average number of common shares outstanding for the period. Diluted net income per
share reflects the potential dilution that could occur if securities or other contracts to issue
common stock (stock options) were exercised or converted into common stock. For the three and nine
months ended June 30, 2000, respectively, approximately 1,000 and 131,000 shares, reflecting the
dilutive effects of outstanding stock options, were included in computing diluted net income per
share.





Comprehensive Income - Comprehensive income for the three months ended June 30, 2000 was
$2,551,000 and $2,631,000 for the three months ended June 30, 1999.



In August 1999, the Company acquired a portfolio of book and online brands
from the Macmillan General Reference Group (the Reference Brands) of Pearson Education for $83.0
million, plus $0.5 million in transaction costs. The acquisition was accounted for as a purchase
business combination and, accordingly, the acquisition cost has been allocated to the fair value of
the assets acquired and liabilities assumed. Assumed liabilities include $2.0 million for the costs
of a restructuring plan involving various settlements and contract terminations ($1.2 million) and
estimated severance and relocation of personnel ($0.8 million). As of June 30, 2000, $1.7 million of
costs had been incurred.

The purchase price allocation is preliminary and subject to revision upon receipt
of final information concerning valuation of intangible assets, working capital received at closing,
and the actual costs of the restructuring plan.

In November and December 1999, the Company sold the J.K. LasserTM and
Chek-Chart brands, respectively, which were purchased in the above-mentioned acquisition, to
unaffiliated companies. The $12.3 million received has been reported as a reduction to branded
trademarks in the first quarter of fiscal 2000, with no gain or loss resulting from the sale.
Transaction costs of $0.5 million resulted in net proceeds of $11.8 million.

In June 2000, the Company sold the ARCO brand imprint to an unaffiliated company.  The $5.7 million received
has been reported as a reduction to branded trademarks in the third quarter of fiscal 2000, with no gain
or loss resulting from the sale. An additional $0.6 million is currently held in escrow and is
expected to be received during the fourth fiscal quarter of 2000. Transaction costs of $0.1 million
resulted in net proceeds of $5.6 million. The sale of this property now completes the Company's
planned divestiture program resulting from the Reference Brands acquisition referred to above.

The Company adopted SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," in fiscal year 1999.  SFAS No. 131 establishes standards for reporting information
about operating segments and related disclosures about geographic information and major
customers.

The Company has two general publishing groups:  Technology and Consumer.  The two segments share
the same infrastructure and personnel, and are not managed as separate operating divisions.
Management evaluates the performance of these segments at the revenue and gross profit level; the
Company's reporting systems do not track or allocate operating expenses or fixed assets by
segment.

The Technology group consists of brands targeted for computer users, from beginning through
advanced level users, including information technology professionals and software developers. The
Consumer group includes brands targeted at the general consumer, including For Dummies®,
CliffsNotesTM , and the recently acquired Reference Brands (Note 3). Net revenue

Item 2.	Management's Discussion and Analysis of Financial Condition and Results of
Operations

Overview

IDG Books Worldwide, Inc. is a leading global knowledge company featuring a diverse
portfolio of technology, consumer, and general how-to book brands, computer-based learning tools, Web sites and Internet e-services.
The Company publishes and markets under well-known brand names, including

Sales of technology-related books account for a majority of the Company's net revenue. Sales of books devoted to
the use of software products sold by Microsoft, including its Windows operating system, accounted for approximately 18% and 44% of
the Company's net revenue for the three months ended June 30, 2000 and 1999, respectively. The Company does not expect the percentage
of net revenue from the sale of books related to Microsoft software products to continue to be as significant.

The Company's customers consist principally of national retail chain booksellers, wholesale distributors, office
superstores, membership clubs, and computer/electronic superstores located primarily in the United States and Canada. Over the last
several years, there has been significant consolidation in the distribution channels for books, including retail outlets, although
alternative distribution channels have emerged. As a result, the Company expects that this trend will lead to increased concentration
within each distribution channel. During the three and nine months ended June 30, 2000, the Company's top three customers accounted
for approximately 38% and 40% of the Company's net revenue as compared to 34% and 36% in 1999. The Company's top ten customers
accounted for approximately 64% of the Company's nine-month net revenue in 2000 as compared to 70% in 1999.

Results of Operations

The following table summarizes the results of operations as a percentage of net revenue for the periods
shown:

_____________________

(1) "EBITDA" is defined as income before provision for income taxes, interest, depreciation and amortization. EBITDA is not intended
to represent cash flows from operations and should not be considered as an alternative to net income as an indicator of the Company's
operating performance or to cash flows as a measure of liquidity. The Company believes EBITDA is a standard measure commonly
reported and widely used by analysts, investors and other interested parties in the publishing and media industries, however, EBITDA, as
presented herein, may not be comparable to similarly titled measures reported by other companies. EBITDA for the three and nine
months ended June 30, 2000 was $7.8 million and $27.5 million, respectively, compared to $5.9 million and $21.8 million for the three
and nine months ended June 30, 1999.

Three Months Ended June 30, 2000 Compared to Three Months Ended June 30, 1999

Net Revenue.  Net revenue increased $13.7 million, or 33.0%, to $55.2 million for the three months ended
June 30, 2000 from $41.5 million for the three months ended June 30, 1999. This increase was primarily the result of an increase in
net revenues of $16.4 million for the Company's Consumer Group, which includes the For Dummies®and
CliffsNotesTMconsumer titles, and acquired Reference Brands. The acquired Reference Brands accounted for $14.9 million
of the Consumer Group growth, which were not included in the third fiscal quarter of 1999. Excluding the acquired Reference Brands,
the Consumer Group's growth was 15.4% for the three months ended June 30, 2000 compared to the comparable period in 1999. The
Technology Group net revenue decreased by $2.7 million to $28.9 million for the third fiscal of 2000, a decrease of 8.7% over the
1999 fiscal third quarter. Of the Company's net revenue for the three months ended June 30, 2000, $8.3 million was attributable to
sales of titles (including new editions) first published during that period, as compared to $12.0 million for titles (including new
editions) first published during the same period for 1999.

Cost of Sales.  Cost of sales increased $8.9 million, or 43.0%, to $29.6 million for the three months ended
June 30, 2000 from $20.7 million for the three months ended June 30, 1999.  Cost of sales as a percentage of net revenue was 53.6%
for 2000 and 49.9% for 1999. Product costs, including paper, printing, and binding expenses, royalty expense and inventory
obsolescence expense increased as a percentage of net revenue to 35.5% for the three months ended June 30, 2000 from 30.0% for the
three months ended June 30, 1999 as a result of a change in product mix. This mix includes a higher percentage of overall sales
related to the Consumer Group which has slightly higher paper, printing and binding costs. Product development costs, which are
relatively fixed, decreased as a percentage of net revenue to 10.7% for the three months ended June 30, 2000 from 12.3% for the three
months ended June 30, 1999, reflecting a decrease in the cost of development of new and cross branded titles.  Fulfillment and
distribution expenses decreased as a percentage of net revenue to 7.3% for the three months ended June 30, 2000 from 7.6% for the
three months ended June 30, 1999 as a result of efficiencies achieved at the Company's new distribution facility.

Selling, General, and Administrative Expenses.  Selling, general, and administrative expenses increased
$2.9 million, or 19.9%, to $17.8 million for the three months ended June 30, 2000 from $14.9 million for the three months ended June
30, 1999.  Approximately 54% or $1.6 million of this increase was attributable to increased selling and marketing expenses, including
increases as a result of the retail marketing incentive program and expenses for other marketing programs where costs increase as net
revenues increase. A significant portion of the increase was also attributable to a $1.3 million increase in general and
administrative expenses including increased occupancy costs for the Company's new San Francisco Internet and New York offices.
Selling, general and administrative expenses as a percentage of net revenue decreased to 32.3% for the three months ended June 30,
2000 from 35.9% for the three months ended June 30, 1999, which can be attributable to operating leverage and efficiencies achieved
for the incremental business associated with the acquired Reference Brands. The Company's sales and marketing costs as a percentage
of net revenue decreased to 19.8% for the three months ended June 30, 2000 from 22.5% for the three months ended June 30, 1999, due
to performance-based customer incentive programs which are driven by net revenue results.

Depreciation and Amortization. The increase of $0.5 million was due to a larger depreciable asset base and
the amortization of intangible assets.

Operating Income. Operating income increased $1.4 million, or 30.2%, to $6.0 million for the three months
ended June 30, 2000 from $4.6 million for the three months ended June 30, 1999. Operating income decreased as a percentage of net
revenue to 10.9% for the three months ended June 30, 2000 from 11.1% for the same period the prior year due to an increase in cost of
sales, as a percentage of net revenue, as described above.

Income Before Provision for Income Taxes. Income before provision for income taxes decreased $0.1 million,
or 2.9% to $4.4 million for the three months ended June 30, 2000 from $4.5 million for the three months ended June 30, 1999.  Income
before provision for income taxes decreased as a percentage of net revenue to 8.0% for the three months ended June 30, 2000 from
10.9% for the three months ended June 30, 1999 due to an increase cost of sales, as a percentage of net revenue, as described above.
In addition, interest expense of $1.6 million for the three months ended June 30, 2000 compared to $0.1 million for the same period
in 1999 on borrowings used to fund the acquisition of the Reference Brands reduced income before provision for income taxes.

Net Income.  Net income of $2.55 million for the three months ended June 30, 2000 decreased $80,000 or 2.9%
from net income of $2.63 million for the three months ended June 30, 1999 for the same reasons as described above.





Nine Months Ended June 30, 2000 Compared to Nine Months Ended June 30, 1999

Net Revenue.  Net revenue increased $54.0 million, or 43.8%, to $177.5 million for the nine months ended
June 30, 2000 from $123.5 million for the nine months ended June 30, 1999. This increase was primarily the result of an increase in
net revenues of $54.4 million for the Company's Consumer Group, which includes the For Dummies®and
CliffsNotesTMconsumer titles, and acquired Reference Brands. The acquired Reference Brands accounted for $49.9 million
of the Consumer Group growth, which were not included in the first nine-months of 1999. Excluding the acquired Reference Brands, the
Consumer Group's growth rate was 16.7% for the nine months ended June 30, 2000 compared to the comparable period in 1999. The
Technology Group net revenue decreased by $0.4 million to $96.5 million for the nine-month period in fiscal 2000, a decrease of less
than one percent over the comparable nine-month period in 1999. Of the Company's net revenue for the nine months ended June 30, 2000,
$30.0 million was attributable to sales of titles (including new editions) first published during that period, as compared to $25.2
million for titles (including new editions) first published during the same period for 1999.

Cost of Sales.  Cost of sales increased $37.3 million, or 61.3%, to $98.2 million for the nine months ended
June 30, 2000 from $60.9 million for the nine months ended June 30, 1999.  Cost of sales as a percentage of net revenue was 55.3% for
2000 and 49.3% for 1999. Product costs, including paper, printing, and binding expenses, royalty expense and inventory obsolescence
expense increased as a percentage of net revenue to 34.4% for the nine months ended June 30, 2000 from 31.4% for the nine months
ended June 30, 1999 as a result of a change in product mix. This mix includes a higher percentage of overall sales related to the
Consumer Group which has slightly higher paper, printing and binding costs. Product development costs, which are relatively fixed,
increased as a percentage of net revenue to 11.4% for the nine months ended June 30, 2000 from 10.6% for the nine months ended June
30, 1999, reflecting an increase in the development of new cross-branded titles.  Fulfillment and distribution expenses increased as
a percentage of net revenue to 9.6% for the nine months ended June 30, 2000 from 7.2% for the nine months ended June 30, 1999 as a
result of one-time costs incurred in the relocation of product to the Company's new distribution facility.

Selling, General, and Administrative Expenses.  Selling, general, and administrative expenses increased
$11.0 million, or 27.0%, to $51.8 million for the nine months ended June 30, 2000 from $40.8 million for the nine months ended June
30, 1999.  Approximately 62% or $6.8 million of this increase was attributable to increased selling and marketing expenses, including
increases as a result of the retail marketing incentive program and expenses for other marketing programs where costs increase as net
revenues increase. A significant portion of the increase was also attributable to a $4.2 million increase in general and
administrative expenses including increased occupancy costs for the Company's new San Francisco Internet and New York offices.
Selling, general and administrative expenses as a percentage of net revenue decreased to 29.2% for the nine months ended June 30,
2000 from 33.1% for the nine months ended June 30, 1999, which can be attributable to operating leverage and efficiencies achieved
for the incremental business associated with the acquired Reference Brands. The Company's sales and marketing costs as a percentage
of net revenue decreased to 17.8% for the nine months ended June 30, 2000 from 20.0% for the nine months ended June 30, 1999, due to
performance-based customer incentive programs which are driven by net revenue results.

Depreciation and Amortization. The increase of $0.7 million was due to a larger depreciable asset base and
the amortization of intangible assets.

Operating Income. Operating income increased $5.0 million, or 27.5%, to $23.0 million for the nine months
ended June 30, 2000 from $18.0 million for the nine months ended June 30, 1999. Operating income decreased as a percentage of net
revenue to 13.0% for the nine months ended June 30, 2000 from 14.6% for the same period the prior year due to  increases in cost of
sales, product development and distribution expenses, as percentages of net revenue, as described above.

Income Before Provision for Income Taxes. Income before provision for income taxes increased $0.2 million,
or 1.1% to $18.1 million for the nine months ended June 30, 2000 from $17.9 million for the nine months ended June 30, 1999.  Income
before provision for income taxes decreased as a percentage of net revenue to 10.2% for the nine months ended June 30, 2000 from
14.5% for the nine months ended June 30, 1999 due to increases in cost of sales, product development and distribution expenses, as
percentages of net revenue, as described above. In addition, net interest expense of $4.9 million for the nine months ended June 30,
2000 compared to $0.1 million for the same period in 1999 on borrowings used to fund the acquisition of the Reference Brands reduced
income before provision for income taxes.

Net Income.  Net income of $10.5 million for the nine months ended June 30, 2000 increased $0.1 million, or
1.4%, from net income of $10.4 million for the nine months ended June 30, 1999 for the same reason as described above.



Financial Condition, Liquidity, and Capital Resources

As of June 30, 2000, the Company's working capital increased $19.3 million to $56.6 million from $37.3 million
as of September 30, 1999. This increase in working capital was the result of a decrease in cash of $1.7 million, an increase in net
accounts receivable of $10.6 million, a $2.3 million decrease in net inventory, and a $3.6 million increase in other current assets
and deferred tax assets. Additionally, there was a $1.4 million increase in accounts payable and a $10.5 million decrease in accrued
liabilities. The significant decrease in accrued liabilities was primarily due to the timing of author royalty payments and customer
marketing and promotional payments.

The net cash (used) by operating activities for the three months ended June 30, 2000 and 1999 was ($1.4) million
and ($0.5) million, respectively.  For the nine months ended June 30, 2000 and 1999 the net cash provided (used) by operating
activities was ($8.5) million and $2.8 million, respectively. The fluctuations are due primarily to changes in accounts receivable
and accrued liabilities.

The Company's net cash provided by investing activities for the nine months ended June 30, 2000 was $4.8 million.
In June 2000 the Company sold its ARCO brand, which was acquired in August 1999 from Pearson Education, Inc., for $5.7 million less
transaction costs of $0.1 million. This sale along with December 1999 sales of the J.K. Lasser and Chek-Chart brands completes the
Company's planned divestiture program resulting from the August 1999 acquisition. Capital expenditures for the three and nine months
ended June 30, 2000 were $7.4 million and $12.0 million, respectively, compared to $0.8 million and $2.4 million for the three and
nine months ended June 30, 1999. Fiscal year 2000 capital expenditures primarily consist of leasehold improvements and equipment for
the Company's new Indianapolis, New York and San Francisco offices.

The Company's net cash provided by financing activities was $2.0 million for the nine months ended June 30, 2000
as a result of issuances of common stock from stock option exercises, and $3.9 million for the nine months ended June 30, 1999 from
advances on the Company's credit facility.

The Company had $0.3 million in cash invested in short-term financial instruments as of June 30, 2000. The Company
believes that its remaining borrowing capacity, together with any cash generated from operations and any funds available under any
future credit facilities, will be sufficient to meet the liquidity requirements of the Company for the foreseeable future. The
Company's future capital requirements will depend on many factors, including, but not limited to, the levels at which the Company
maintains inventory, the market acceptance of the Company's products, the levels of promotional activities and advertising required
to launch the Company's products, and any future acquisitions. To the extent that the available cash, together with existing
resources and future earnings, are insufficient to fund the Company's future activities, the Company may need to raise additional
funds through public or private financing. No assurance can be given that any such additional funding will be available or that, if
available, can be obtained on terms favorable to the Company.

Factors Affecting Future Operating Results

Dependence on Microsoft Products and Competition with Microsoft Press.

In addition to relying on the sales of books devoted to Microsoft products, the Company competes with Microsoft's
publishing division, Microsoft Press, for readers of computer-related books, including books covering Microsoft products. Microsoft
Press has substantially greater financial resources than the Company and, because it is owned by Microsoft, may have better access to
planned and new Microsoft products. As a result, Microsoft Press may have a competitive advantage over the Company in providing books
devoted to the use of software products sold by Microsoft.

Dependence on For DummiesÒ
 Publications.  The Company derives a material portion of its net revenue from the sale of the For DummiesÒ brand of books. In addition, the Company has devoted substantial resources to the publication of these books and the development
of the For DummiesÒ brand name. As a result, any change in reader preferences leading to a decline in demand for the For DummiesÒ books would likely have a material adverse effect on future financial results.

Risks of New Product Introductions.  Generally, as a particular book gets older, the Company sells fewer
copies of that book.  Consequently, the Company's future success depends on its ability to identify trends in the technology,
business, and self-help markets and to offer new titles, as well as other products and services, that address the changing needs of
the target audiences. To establish market acceptance of a new publication, the Company must dedicate significant resources to
research and editorial development, production, and sales and marketing. The Company incurs significant costs in developing,
publishing, and selling a new book, which often significantly precede meaningful revenues from its sale. Consequently, new
publications can require significant time and investment to achieve profitability. Investors should note, however, that there can be
no assurance that the Company's efforts to introduce new publications or other products or services will be successful or profitable.

The Company records as an expense the costs related to the development of new publications and products, other
than author advances, as products are introduced. As a result, the Company's profitability from quarter to quarter and from year to
year may be adversely affected by the number and timing of new publications and product launches in any period and the level of
acceptance gained by such publications and products.

Risks Associated with Fluctuations in Paper Costs.  Paper is the principal raw material used in the
Company's business. The Company generally purchases paper from merchants representing the paper mills. The Company does not have
long-term paper supply contracts with these paper merchants. The arrangements with merchants are negotiated each year and provide for
quarterly price adjustments. Paper prices have been volatile over the past several years and are affected by many factors, including
demand, mill capacity, pulp supply, energy costs, and general economic conditions. Consequently, the Company's cost of paper,
relative to our net revenue, can vary from period to period. In the past, paper has also been difficult to obtain due to industry-
wide shortages. Significant paper price increases, sustained over a period of time, could adversely affect the Company's future
financial condition or operating results.

Fluctuations in Quarterly Results and Cyclicality of Revenue.  The Company's operating expenses, which
include product development costs and selling, general, and administrative expenses, are relatively fixed in the short term and are
based on our long term revenue expectations. If the Company sells fewer books or otherwise has lower revenue than expected, the
Company may not be able to quickly reduce its spending.  Any shortfall in the Company's revenue would have a direct impact on its
results of operations, and fluctuations in quarterly results could affect the market price of its common stock in a manner unrelated
to the Company's long-term operating performance. The Company typically sells more books during the first and second quarters of its
September fiscal year because of increased sales during the Christmas season. In addition, the Company typically sells more books in
quarters in which software manufacturers release new or updated versions of popular software products. Because a substantial portion
of the Company's selling, general, and administrative expenses are incurred evenly throughout the year, the Company generally
experiences relatively lower net profit during quarters not impacted by increases in net revenue due to seasonal or other factors
discussed above.

In addition, the Company typically publishes books relating to new trends and technologies. Accordingly, if
general economic conditions worsen, people may defer spending on these new trends and technologies, which could reduce the number of
books sold.

Risks Associated with Product Distribution Channels; Risk of Product Returns.  The Company sells its books
primarily to large retail chains, large wholesalers, warehouse clubs, office superstores, and computer and electronics superstores.
For the three months ended June 30, 2000 the Company's three largest customers, Barnes & Noble, Inc., Borders, Inc., and Ingram
Book Company accounted for approximately 18%, 13%, and 7% of net revenue, respectively. The Company's future financial results depend
in large part on its relationships with its customers. Any disruption in relationships with its customers could adversely affect
financial performance.

The Company's sales policy generally permits book customers to return any unsold or damaged books for full credit.
The Company records as revenue all books sold to its customers in a particular quarter and, at the same time, records a provision for
estimated returns. During the three months ended June 30, 2000, the Company recorded a provision for returns of approximately 22% of
its gross sales. If, during any period, customers return more books than previously estimated, the Company's financial results in
that period would be adversely affected.

Competition.  The Company faces competition directly from other book publishers and indirectly from non-
print media.  Competition in book publishing stems mainly from editorial quality, timely introduction of new titles, product
positioning, pricing, and brand name recognition. In addition to the Company, Pearson Education, Inc., Microsoft Press, and McGraw-
Hill all have a strong market presence in the United States and internationally in technology publishing.  The principal competitors
for the Company's business and self-help titles include Random House, Simon & Schuster, and HarperCollins.  Each of these
competitors has substantially greater financial resources than the Company.

Non-print media, such as the Internet and CD-ROMs, may also present substantial competition. If computer users
increase their reliance on instruction and other information disseminated on-line, the Company's business could be adversely
affected.

Control by IDG (Parent); Potential Conflicts of Interests; Benefits to IDG.  The parent owns all of the
shares of the Class B common stock, each share of which is entitled to ten votes per share on most stockholder actions, and has
approximately 76% of the combined voting power of both classes of common stock as of June 30, 2000. The remaining holders of the
shares of Class A common stock are entitled to one vote per share and have approximately 24% of the combined voting power. The parent
has two representatives on the Company's Board of Directors and has enough votes to elect all members of the Board of Directors. As a
result of its stock ownership, the parent is in a position, without the approval of the Company's public stockholders, to amend the
Company's charter or approve a merger, sale of assets, or other major corporate transaction; defeat any non-negotiated takeover
attempt that might otherwise benefit the public stockholders; determine the amount and timing of dividends paid to itself and to the
Company's public stockholders; and otherwise control the Company's management and operations and the outcome of all matters submitted
for a stockholder vote that could conflict with the interests of its public stockholders. In January 2000, the parent announced its
plans to purchase up to 500,000 shares of IDGB common stock from time to time at prevailing market prices.

Dependence on Key Personnel. The Company relies, and will continue to rely, on its senior executive
officers and other key management personnel. During the second fiscal quarter the Company completed its search for two key executive
officers, a President and Chief Financial Officer, to fill two open positions due to prior resignations. In January 2000, the Company
announced the appointment of William G. Barry as President and Chief Operating Officer, effective March 1, 2000. Mr. Barry is the
former Senior Vice President, Corporate Development of Random House, Inc. In April 2000 the Company announced the appointment of John
M. Harris as Senior Vice President and Chief Financial Officer, effective May 1, 2000. Mr. Harris is the former Chief Financial
Officer of Marketplace by Marriott, a $4 billion global procurement startup. If any senior executives or key management leave the
Company, the relationships that these people have with the Company's authors, customers, manufacturers, or investors could be lost,
and the Company would need to find people who could develop new relationships. In addition, the Company expects that it will need to
hire additional employees, including key management positions for Internet business development. The competition for employees at all
levels of the book publishing and Internet industries is intense and is increasing. In our Northern California operations, in
particular, the Company has experienced increased turnover of employees and is experiencing difficulty in attracting new employees.
If the Company does not succeed in attracting new employees or retaining and motivating current employees, the Company's business
could suffer significantly.

Transition to New Distribution Service. The Company historically outsourced distribution and fulfillment
functions to retail and wholesale customers through two vendors. During the first fiscal quarter of 2000, the Company began the
transition of these services to a new single source facility in Virginia. This transition was completed at the end of the fiscal
third quarter.

Risks Associated with Acquisitions. As part of the Company's growth strategy, it may buy or make
significant investments in, complementary companies, publications or products. The Company has completed the acquisition of Cliffs
Notes, Inc. and recently completed the acquisition of the Reference Brands. These acquisitions, as well as any future acquisition,
will be accompanied by the risks commonly encountered in making acquisitions of products, companies, and technologies.

For example, it could have difficulty assimilating the personnel and operations of the acquired company.  This
could cause a disruption of its ongoing business, distraction of management and other resources, and difficulty in maintaining
uniform standards, controls, and procedures. There can be no assurance that the Company would succeed in overcoming these risks or
any other problems encountered in connection with any acquisitions it may make. In addition, the Company may be required to incur
additional debt or issue equity to pay for any future acquisitions



Financial Market Risks

For the three months ended June 30, 2000, there were no material changes in the Company's exposure to
financial market risks, including changes in interest rates and foreign currency exchange rates.
