The Library of Congress is committed to cataloging through cooperation. Immense benefits are derived by the world wide library community through cataloging cooperatively. The records created for serials, manuscripts, monographs, and name or subject authorities contribute to the world wide endeavor to bring all knowledge, regardless of format, under bibliographic control in order to make it accessible to the world wide community. The more we cooperate, the more we accomplish.
Program for Cooperative Cataloging (PCC)
The Library of Congress operates as a permanent member of this program and serves as the PCC Secretariat to coordinate, support, and provide service to members in the various component programs of the PCC: Name Authority Cooperative Program (NACO), Bibliographic Record Cooperative Program (BIBCO), CONSER (Cooperative Online Serials) Program, and Subject Authority Cooperative Program (SACO).
National Union Catalog of Manuscript Collections (NUCMC)
This program provides and promotes bibliographic access to the nation’s documentary heritage by providing bibliographic access to archival collections held by eligible archival repositories throughout the U.S. and its territories, and by providing free searching, via a NUCMC gateway, of archival collections in OCLC WorldCat.
Catalogers Learning Workshop (CLW)
This website provides access to professional training resources related to the organization and classification of bibliographic information. All CLW course materials are available free of charge in PDF format.
Policy, Training, and Cooperative Programs Division (PTCP)
As of June 1, 2019, LC staff that work directly in support of the PCC and NUCMC programs merged into the newly formed Policy, Training, and Cooperative Programs Division (PTCP) of the Acquisitions and Bibliographic Access Directorate. This merger into a single division achieves greater efficiencies in cooperative ventures, stimulates their growth and visibility, and enables staff members working in these two areas to provide better support and service to the members of the programs.
