What is CIP Data?

"CIP data" in its broadest sense refers to the bibliographic record created by the Library of Congress for a book prior to its publication. Strictly speaking, however, "CIP data" is the bibliographic record that appears printed on the verso of the book's title page. It is an abbreviated version of the machine-readable cataloging (or MARC) record that resides in the Library's database and which is distributed to libraries and book vendors. The full MARC version contains additional information such as codes that indicate the language in which the book is written, the date when the book was cataloged, etc.

A new version of the CIP Data Block was implemented on October 1, 2015.

The Library of Congress with the assistance of experts from the school, public and academic library communities investigaed revisions to the CIP Data Block. The new CIP Data Block is the result of an analysis of survey results done in 2014 that asked institutions what should be kept, added, or removed from the CIP Data Block to meet the needs of the twenty-first century bibliographic environment. There are numerous changes to the data block layout, including the use of labels to clearly identify the different components within the block, addition of Resource Description and Access (RDA) and electronic resource data elements, and a URL that links directly to the LC catalog for easy retrieval of bibliographic records. The proposed version of the CIP Data Block was shared at the 2015 Midwinter Meeting of the American Library Association. After incorporating recommendations received at the conference, the Library of Congress made some revisions and requested further input through June 1, 2015.  Additional changes were made based on this input.

A summary of the changes, examples of the new CIP Data Block, and a list of MARC fields that are included or excluded can be found at:

The revisions to the CIP data block, as it will appear in books, will not impact MARC records created by the Library of Congress, and the Library’s MARC record distribution process will remain unchanged.
