All CGP Records (MARC XML)

General Information

The U.S. Government Publishing Office (GPO) is making available all MARC bibliographic records (1,115,162 records) in the Catalog of U.S. Government Publications (CGP) as of February 2026. The CGP is the U.S. Government Publishing Office's (GPO) finding tool for electronic and print publications from the legislative, executive, and judicial branches of the U.S. Federal Government. These publications comprise the National Bibliography of U.S. Government Publications.

These files and the monthly CGP files in the CGP MARC Records collection essentially represent the entire CGP. GPO may periodically refresh the files in the All_CGP_Records collection with a new snapshot of the whole CGP.

The records are in MARC XML. The total size of the zipped files is 357 MB. Each of the 28 files in the repository holds approximately 40,000 records.

Please note: there are approximately 3,000 MARC XML validation errors.

These same records are also available in UTF-8 format from the cataloging-records-all-cgp-utf8 repository.
