R.H. DONNELLEY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1.  Background and Basis of Presentation

     On December 17, 1997, the Board of Directors of The Dun & Bradstreet
Corporation ('D&B') approved in principle a plan to separate into two publicly-
traded companies - R.H. Donnelley Corporation (the 'Company') and The New Dun &
Bradstreet Corporation ('New D&B').  The distribution ('Distribution') was the
method by which D&B distributed to its stockholders shares of New D&B common
stock, which represent a continuing interest in the D&B businesses now conducted
by New D&B.  On July 1, 1998, as part of the Distribution, D&B distributed to
its stockholders shares of New D&B stock. Shares of D&B common stock held by D&B
stockholders represent a continuing ownership interest in the Company.  In
connection with the Distribution, D&B changed its name to R.H. Donnelley
Corporation and D&B common stock has become the Company's common stock (the
'Common Stock').  After the Distribution, the Company's only operating
subsidiary is R.H. Donnelley Inc. ('Donnelley').  Therefore, on a consolidated
basis, the financial statements of the Company and Donnelley are substantially
identical.  The financial statements of the Company have been restated to
reflect the recapitalization.

     The financial statements reflect the financial position, results of
operations, and cash flows of the Company as if it were a separate entity.  The
financial statements include allocations of certain D&B corporate headquarters
assets, liabilities and expenses relating to the Company's businesses that were
transferred from D&B on June 30, 1998.  Management believes these allocations
are reasonable.  However, the costs of these services and benefit charges are
not necessarily indicative of the costs that would have been incurred if the
Company had performed or provided these functions as a separate entity.

     These interim financial statements have been prepared in accordance with
the instructions to Form 10-Q and should be read in conjunction with the
financial statements and related notes of the Company for the year ended
December 31, 1997.  The results of interim periods are not necessarily
indicative of results for the full year or any subsequent period.  In the
opinion of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation of financial position, results of
operations and cash flows at the dates and for the periods presented have been
included.

</TABLE>

     As required by SFAS No. 128, the Company has provided a reconciliation of
basic weighted average shares to diluted weighted average shares within the
table outlined above.  The conversion of diluted shares has no impact on
operating results. The Company's options generally expire 10 years after the
initial grant date.



3.  Comprehensive Income

     Effective January 1, 1998, the Company adopted SFAS No. 130, 'Reporting
Comprehensive Income'.  This statement requires that all items recognized under
accounting standards as components of comprehensive earnings be reported in a
financial statement for the period in which they are recognized and displayed
with the same prominence as other financial statements.  There were no
additional components of comprehensive income and, as a result, the Company's
total comprehensive income for the three and six month periods ended June 30,
1998 and 1997 were equal to net income for those periods.

4.  Commitment

     On June 5, 1998, Donnelley entered into a credit agreement with the Chase
Manhattan Bank, as Administrative Agent, and the Lenders party thereto (the
'Credit Agreement').  Under the terms of the Credit Agreement, Donnelley
obtained a Senior Revolving Credit Facility of $100 million and Senior Secured
Term Facilities in the aggregate amount of $300 million, of which Donnelley has
borrowed $350 million payable over a maximum period of 8.5 years.  As of June
30, 1998, the weighted average interest rate under the Credit Agreement was
7.422% per annum.  Also on June 5, 1998, Donnelley issued $150 million of Senior
Subordinated Notes.  These Notes pay interest semi-annually at the annual rate
of 9.125% and are due in 2008.  The net proceeds of the $500 million was
dividended to D&B (and distributed to New D& B in connection with the
Distribution), but repayment of such indebtedness remains an obligation of
Donnelley, and is guaranteed by the Company.

     On June 16, 1998 Donnelley entered into interest rate swap agreements to
reduce the impact of changes in interest rates on its floating rate long-term
debt under the Credit Agreement.  At June 30, 1998, Donnelley had outstanding
three interest rate swap agreements, having a total notional principal amount of
$175 million.  These agreements effectively change the interest rate on $175
million of floating rate borrowing to fixed rates.  The interest rate swap
agreements have terms of three to five years.  Donnelley is exposed to credit
risk in the event of nonperformance by the other party to the interest rate swap
agreements.  However, Donnelley does not anticipate nonperformance by the
counterparty.

5.  Litigation

     On July 29, 1996, Information Resources, Inc. ('IRI') filed a complaint in
the United States District Court for the Southern District of New York, naming
as defendants D&B, A.C. Nielsen Company and IMS International Inc. (the 'IRI
Action').  New D&B has assumed and will indemnify the Company against any
payments to be made by the Company in respect to the IRI Action under the 1996
Distribution Agreement between D&B, Cognizant and ACNielsen, under the Indemnity
and Joint Defense Agreement or otherwise, including any ongoing legal fees and
expenses related thereto.

     In the normal course of business, the Company is subject to proceedings,
lawsuits and other claims.  In the opinion of  management, the outcome of such
current legal proceedings, claims and litigation will not materially affect the
Company's financial position or results of operations on an annual basis.

6.  DonTech Partnerships

     In 1991, Donnelley formed a general partnership with an affiliate of
Ameritech Corporation ('Ameritech'), the DonTech Partnership ('DonTech I').
Prior to August 1997, DonTech I solicited advertising, published and delivered
various directories in Illinois and Northwest Indiana.  During August 1997,
Donnelley signed a series of agreements with Ameritech changing the structure of
the existing partnership.  A new partnership was formed ('DonTech') which was
appointed the exclusive sales agent, in perpetuity, for yellow page directories
published by Ameritech in Illinois and Northwest Indiana.  The Company also
receives direct fees from Ameritech (Revenue Participation) which are tied to
advertising sales and are not included in the financial information below.

     The following are summarized combined financial information of the DonTech
Partnerships:

7.  Adoption of Statement of Financial Accounting Standards

     In June, 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ('SFAS') No. 133, 'Accounting for Derivative
Instruments and Hedging Activities' ('SFAS No. 133'), which establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts, and for hedging activities.
SFAS No. 133 is effective for all fiscal quarters of all fiscal years beginning
after June 15, 1999.  Restatement of prior period financials is not required.
The Company is in the process of evaluating the effect this statement will have
on its financial statements and footnote disclosures.

8.  Subsequent Events

     On July 14, 1998 the Company announced that a special shareholders' meeting
would be held to vote on a proposal to execute a reverse one-for-five stock
split.  The shareholders' meeting has subsequently been scheduled for August 24,
1998 and the record date was July 27, 1998.  The proposed reverse split would be
effective shortly after its approval by the stockholders.

     On July 14, 1998 the Company also announced plans to repurchase up to 15
million shares of its Common Stock under a systematic stock repurchase plan.
The repurchase authorization will be revised to three million shares if the
Company's planned reverse stock split is approved.  The primary purpose of the
repurchase is to offset shares issued under the Company's employee and director
compensation plans.  The shares are expected to be purchased periodically over a
three-year period in the open market, in accordance with guidelines established
by the Securities and Exchange Commission.  Stock purchased under this
authorization would be held as treasury stock and would be available for
issuance upon exercise of employee stock options and for compensation plans.

     On July 14, 1998, the Board of Directors declared a dividend of $0.035 per
share payable on September 10, 1998 to holders of record on August 20, 1998.

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

    The matters discussed in this Form 10-Q of R.H. Donnelley Corporation (the
'Company') and R.H. Donnelley Inc. ('Donnelley') contain forward looking
statements that involve risks and uncertainties including risks associated with
developments in the telecommunications industry, including the ongoing
consolidation of telecommunications providers, trends towards alternatives to
print advertising and other risks detailed from time to time in the Company's
and Donnelley's filings with the Securities and Exchange Commission. These
statements reflect the Company's current beliefs and specific assumptions with
respect to future business decisions and are based on information currently
available.  Accordingly, the statements are subject to significant risks,
uncertainties and contingencies which could cause the Company's actual
operating results, performance or business prospects to differ from those
expressed in, or implied by, these statements.

FINANCIAL REVIEW

     On December 17, 1997, the Board of Directors of The Dun & Bradstreet
Corporation ('D&B') approved in principle a plan to separate into two publicly-
traded companies - the Company and The New Dun & Bradstreet Corporation ('New
D&B').  The distribution ('Distribution') was the method by which D&B 
distributed to its stockholders shares of New D&B common stock, which represent 
a continuing interest in the D&B businesses now conducted by New D&B.  On July 
1, 1998, as part of the Distribution, D&B distributed to its stockholders shares
of New D&B stock. Shares of D&B common stock held by D&B stockholders represent 
a continuing ownership interest in the Company.  In connection with the
Distribution, D&B changed its name to R.H. Donnelley Corporation and D&B common
stock has become the Company's common stock (the 'Common Stock').  After the
Distribution, the Company's only operating subsidiary is Donnelley.

     Over the last 18 months, certain events and transactions occurred which
impact the comparability of the three and six month results for 1997 and 1998.
In August 1997, Donnelley signed a series of agreements with an affiliate of
Ameritech ('Ameritech') changing the structure of the existing DonTech
partnership ('DonTech I').  A new partnership was formed ('DonTech') and was
appointed the exclusive sales agent, in perpetuity, for yellow page directories
published by Ameritech in Illinois and Northwest Indiana (the 'DonTech
Restructuring').  Prior to the DonTech Restructuring, the Company recognized
revenues and costs for DonTech I when related directories were published.  Under
the new structure, DonTech now recognizes revenues and costs when a customer
signs a sales contract.  However, the effect of the DonTech Restructuring should
not, on an annual basis, result in materially different financial results than
during 1997.  Also subsequent to the second quarter of 1997, the Company's
contract with Cincinnati Bell expired in August 1997 and in December 1997, the
Company sold its Proprietary-East business ('P-East').  Finally, changes in
scheduling of directory publication dates and sales campaigns for both DonTech
and Bell Atlantic make quarterly comparisons difficult over the time period.

Three Months Ended June 30, 1998 Compared with Three Months Ended June 30, 1997

     Gross advertising sales is the billing value of advertisements sold by the
Company including DonTech. Gross advertising sales figures set forth below are
presented on the same basis on which revenue is recognized (that is, when a
customer signs a sales contract where the Company is a sales agent or where the
directory is published where the Company is the publisher).  Gross advertising
sales in the second quarter of 1998 increased $21.0 million, from $233.9 million
in the second quarter of 1997 to $254.9 million in the second quarter of 1998.
Excluding P-East and Cincinnati Bell gross advertising sales of $17.1 million
and $49.9 million, respectively, gross advertising sales increased by $88.0
million, of which $73.4 million was due to the DonTech Restructuring.  The
remaining increase of $14.6 million is primarily due to a shift in scheduling of
certain sales campaigns in the Bell Atlantic region.

     On a publication cycle basis (that is, reflecting sales when a directory is
published, regardless of the Company's role), gross advertising sales of $255.5
million were down slightly compared to the prior year period amount of $257.5
million (exclusive of Cincinnati Bell and P-East).  Good growth at DonTech was
offset by lower sales in Bell Atlantic's New York City directories.  The Company
believes that presenting gross advertising sales on a publication cycle basis
may provide a more meaningful comparison of the Company's sales cycle from
period to period, and intends to present gross advertising sales on a
publication cycle basis in future periods.

     Revenues are derived from commissions related to advertising sales and do
not include revenues generated by sales of advertising by the DonTech
partnership.  Revenues decreased from $60.5 million in the second quarter of
1997 to $38.0 million in the second quarter of 1998.  Excluding P-East and
Cincinnati Bell revenue of $13.9 million and $13.1 million, respectively,
revenues increased from $33.5 million to $38.0 million.  The increase is
primarily due to the shift in the scheduling of certain sales campaigns in the
Company's Bell Atlantic markets, which resulted in a $2.6 million increase in
revenues in those markets.  In addition, publishing revenues increased by $1.6
million principally due to revenues for publishing services which the Company
began providing to an independent yellow pages publisher in 1998 under a long-
term agreement.

  Partnership income and related fees increased to $36.6 million in the second
quarter of 1998 from $10.3 million in the second quarter of 1997.  Of this
increase, $27.3 million is attributable to DonTech.  Under the terms of the
DonTech Restructuring, the Company receives 50% of the profits generated by the
partnership and receives direct fees from Ameritech which are tied to
advertising sales generated by the partnership.  The effect of the DonTech
Restructuring on quarterly results for 1998 and forward is that partnership
income and related fees will be recognized more evenly throughout the year than
under the previous arrangement.  The Company also receives 50% of the profits
generated by the CenDon partnership, a partnership between Donnelley and an
affiliate of Sprint.  In the second quarter of 1998, the Company's partnership
income from CenDon was essentially flat with 1997.

     The Company's operating and general and administrative expenses decreased
by $24.9 million from $55.4 million in the second quarter of 1997 to $30.5
million in the second quarter of 1998.  Excluding P-East and Cincinnati Bell
operating expenses of $13.7 million and $6.9 million, respectively, in 1997,
these costs decreased by $4.3 million.  This decrease is primarily attributable
to lower corporate expenses.

     The Company's operating income increased $29.3 million from $9.8 million in
the second quarter of 1997 to $39.1 million in the second quarter of 1998.
Excluding P-East and Cincinnati Bell operating income of $1.0 million and $6.2
million, respectively, in the second quarter of 1997, operating income increased
$36.5 million.  This increase is primarily due to the DonTech Restructuring,
decreased corporate expenses and increased revenue in the Bell Atlantic markets
and in publishing operations.

     Interest expense of $3.0 million in the second quarter of 1998 represents
the interest on the Debt (as defined below) for the period June 5 through June
30 (see ' - Liquidity and Capital Resources').





<PAGE>

Six Months Ended June 30, 1998 Compared with Six Months Ended June 30, 1997

     Gross advertising sales in the first half of 1998 increased $100.0 million
from $302.1 million in the first half of 1997 to $402.1 million in the first
half of 1998.  Excluding P-East and Cincinnati Bell gross advertising sales of
$18.6 million and $50.0 million, respectively, gross advertising sales increased
by $168.6 million, of which $139.0 million was due to the DonTech Restructuring.
The remaining increase of $29.6 million is primarily due to scheduling shifts
for certain sales campaigns  in the Bell Atlantic region.

     On a publication cycle basis, gross advertising sales for 1998 were $458.3
million, compared to $452.1 million, exclusive of Cincinnati Bell and P-East,
for the first six months of 1997.  Good  growth at DonTech was offset by lower
sales in Bell Atlantic's New York City directories.

     Revenues decreased from $80.7 million in the first half of 1997 to $62.3
million in the first half of 1998.  Excluding P-East and Cincinnati Bell
revenues of $14.5 million and $13.1 million, respectively, in the first half of
1997, revenues increased from $53.1 million in 1997 to $62.3 million in 1998.
The increase is primarily due to the shift in the scheduling of certain sales
campaigns in the Company's Bell Atlantic markets, which resulted in a $5.7
million increase in revenues.  Publishing revenues also increased by $3.3
million principally due to publishing services which the Company began providing
to an independent yellow pages publisher in 1998.

  Partnership income and related fees increased by $46.5 million from $15.7
million in the first half of 1997 to $62.2 million in the first half of 1998.
This increase is attributable to the DonTech Restructuring.

     The Company's operating and general and administrative expenses decreased
by $22.6 million, from $77.9 million in the first half of 1997 to $55.3 million
in the first half of 1998.  Excluding P-East and Cincinnati Bell operating
expenses of $15.2 million and $6.9 million in 1997, respectively, these costs
decreased by $0.5 million, primarily due to reduced corporate expenses.

     The Company's operating income increased by $51.9 million from $7.5 million
in the first half of 1997 to $59.4 million in the first half of 1998.  Excluding
P-East and Cincinnati Bell operating income of $0.1 million and $6.2 million in
the first half of 1997, respectively, operating income increased $58.2 million.
The operating income increase in the first half of 1998 is primarily due to the
DonTech Restructuring, increased revenues in Bell Atlantic and increased
revenues from publishing operations.

     Interest expense of $3.0 million in the first half of 1998 represents the
interest on the Debt.

Changes in Financial Position at June 30, 1998 Compared with December 31, 1997

     The Company's assets increased modestly in the first half of 1998.  This
increase is primarily due to an increase in other long-term assets and deferred
contract costs, partially offset by a decrease in partnership investments.  The
increase in other long term assets is primarily due to the payment and
capitalization of financing costs relating to the Debt.  Deferred contract costs
represent incurred costs associated with revenue that is recognized later in the
year; this increase is consistent with prior years.  The Company's partnership
investment decreased $19.3 million in the first half of 1998, which is primarily
attributable to the wind down of the DonTech I partnership as a result of the
DonTech Restructuring.  Also, as a result of the DonTech Restructuring, the
direct fees from an affiliate of Ameritech are recorded as accounts receivable
which resulted in a $31.9 million increase in accounts receivable.  However,
total accounts receivable, net was essentially unchanged because the
aforementioned increase was offset by a $32.6 million decrease due to normal
cyclical operating collections in the Bell Atlantic and Sprint businesses.

     The Company's total liabilities increased by $494.1 million in the first
half of 1998, primarily due to the recording of the Debt.

Liquidity And Capital Resources

Six Months Ended June 30, 1998 Compared with Six Months Ended June 30, 1997

     Cash and cash equivalents at June 30, 1998 and June 30, 1997 were $208,000
and $57,000, respectively.  These balances reflect D&B's centralized cash
management system, where historically cash deposits were transferred to D&B on a
daily basis and D&B funded Donnelley's disbursement bank accounts as required.

     Net cash provided by operations was $35.8 million in the first half of 1998
and $93.6 million in the first half of 1997, a decrease of $57.8 million.
Excluding cash provided by P-East in the first half of 1997 of $16.4 million,
cash provided by operations in the first half of 1998 decreased by $41.4
million.  The decrease is primarily due to a change in the timing of cash
receipts from DonTech related to the DonTech Restructuring. The Company has
available credit capacity under the Revolver, as defined below, which may be
used as necessary to offset any fluctuations in liquidity caused by the timing
of cash receipts from DonTech and other operations and for such other purposes
as the Company may from time to time determine.

     Net cash used in investing activities was $7.3 million in the first half of
1998, compared to $11.4 million in the first half of 1997.  The higher capital
spending in 1997 is primarily attributable to purchases of computer equipment
and furniture and fixtures in connection with office moves made late in 1996.
Currently, the Company has no material commitments for capital spending.

     Net cash used in financing activities represents cash transferred to D&B
throughout the first half of the year.  As stated above, historically all cash
deposits have been transferred to D&B on a daily basis and D&B has funded
Donnelley's disbursement bank accounts as required.  The net amounts transferred
to D&B were $518.8 million in the first half of 1998 and $82.2 million in the
first half of 1997.  The increased transfer in 1998 is primarily due to the net
cash received in connection with the Debt.

       On June 5, 1998, Donnelley entered into a credit agreement with the Chase
Manhattan Bank, as Administrative Agent, and the Lenders party thereto (the
`Credit Agreement').  Under the terms of the Credit Agreement,  Donnelley
obtained a Senior Revolving Credit Facility of $100 million (the `Revolver') and
Senior Secured Term Facilities in the aggregate amount of $300 million, of which
Donnelley initially borrowed $350 million payable over a maximum period of 8.5
years.  As of June 30, 1998, the Company has $350 million of outstanding debt
under the Credit Agreement  at a weighted average interest rate of 7.422% per
annum.  In addition, Donnelley issued $150 million of Senior Subordinated Notes
(the `Notes').  These Notes pay interest semi-annually at the annual rate of
9.125%, and are due in 2008.  The net proceeds of the $500 million (the `Debt')
was dividended to D&B (and distributed to New D&B in connection with the
Distribution), but repayment of such indebtedness remains an obligation of
Donnelley, and is guaranteed by the Company. The Credit Agreement and the
Indenture governing the Notes each contain various financial and other
restrictions, including restrictions on indebtedness, capital expenditures and
commitments.
     
     To reduce the impact of changes in interest rates on its floating rate 
long-term debt under the Credit Agreement, Donnelley subsequently entered into 
three interest rate swap agreements having a total notional principal amount of 
$175 million.  These agreements effectively change the interest rate on $175 
million of floating rate borrowing to fixed rates.  The interest rate swap 
agreements have terms of three to five years.  Donnelley is exposed to credit 
risk in the event of nonperformance by the other party to the interest rate swap
agreements. However, Donnelley does not anticipate nonperformance by the 
counterparty.

     The Company believes that cash generation, together with available debt
capacity under the Revolver will be sufficient to permit the Company to fund its
cash requirements, including its operating expenses, anticipated capital
expenditures and its debt service requirements, for the foreseeable future.

ADOPTION OF STATEMENT OF FINANCIAL ACCOUNTING STANDARDS

     In June, 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (`SFAS') No. 133, `Accounting for Derivative
Instruments and Hedging Activities' (`SFAS No. 133'), which establishes 
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts, and for hedging activities.
SFAS No. 133 is effective for all fiscal quarters of all fiscal years beginning 
after June 15, 1999.  Restatement of prior period financials is not required.  
The Company is in the process of evaluating the effect this statement will have 
on its financial statements and footnote disclosures.
