                  Re: Registration Statement on Form S-4 filed by R.H. Donnelley
                      Corporation (the "REGISTRATION STATEMENT")

Ladies and Gentlemen:

     I am the Vice President, General Counsel and Corporate Secretary of R.H.
Donnelley Corporation, a Delaware corporation (the "COMPANY"), and have acted in
such capacity in connection with the Registration Statement, which relates to
the proposed issuance and exchange (the "Exchange Offer") of up to $300 million
aggregate principal amount of the Company's 6.875% Senior Notes due 2013 (the
"EXCHANGE NOTES") registered under the Securities Act of 1933 for an equal
principal amount of the Company's 6.875% Senior Notes due 2013 (the "Outstanding
Notes"). The Outstanding Notes have been, and the Exchange Notes will be, issued
pursuant to an Indenture, dated as of January 14, 2005 (the "INDENTURE"), by and
between the Company and The Bank of New York, as trustee (the "TRUSTEE").

     In connection with the opinion expressed herein, I have examined such
documents, records and matters of law as I have deemed relevant or necessary for
purposes of this opinion. Based on the foregoing, and subject to the further
limitations, qualifications and assumptions set forth herein, I am of the
opinion that:

     The Exchange Notes, when they are executed by the Company, authenticated by
the Trustee in accordance with the Indenture and delivered in exchange for the
Outstanding Notes in accordance with the terms of the Exchange Offer, will be
validly issued by the Company and will constitute valid and binding obligations
of the Company.

     My opinion is limited by bankruptcy, insolvency, reorganization, fraudulent
transfer, conveyance, voidable preference, moratorium or other similar laws,
regulations or judicial opinions of general applicability relating to or
affecting creditors' rights generally, and by general equitable principles,
whether such principles are considered in a proceeding at law or at equity.

     My examination of matters of law in connection with the opinion expressed
herein has been limited to, and accordingly my opinion herein is limited to, the
laws of the State of New York, the General Corporation Law of the State of
Delaware, including the applicable provisions



of the Delaware Constitution and the reported judicial decisions
interpreting such law. I express no opinion with respect to any other law of the
State of Delaware or any other jurisdiction.

     I hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement and to the reference to me under the caption "Legal
Matters" in the Prospectus constituting a part of the Registration Statement. In
giving such consent, I do not hereby admit that I am included in the category of
persons whose consent is required under Section 7 of the Securities Act of 1933
or the rules and regulations of the Securities and Exchange Commission
promulgated thereunder.


                                    Very truly yours,

                                    /s/ Robert J. Bush
