PCC Values Statement

The Program for Cooperative Cataloging responds to changing needs of users with

  • development of and adjustments to standards
  • dynamic metadata
  • willingness to work in shared files
  • adaptation of metadata from non-library sources
  • collaboration with archives, museums, publishers, vendors, and others
  • creative usage of automation
  • extension of bibliographic control to a maximum range of resources of interest to users
  • continuing education and training for metadata creators

PCC Vision Statement

Among libraries, archives, museums, publishers, and vendors, sufficiently interoperable metadata exists to permit users to search effectively across the entire information space.

Monographic Bibliographic Record Program (BIBCO)

Through this program, members contribute bibliographic records to globally-distributed databases. These records are identified as PCC records and are notable for their complete authority work (both descriptive and subject), a call number from a recognized system (such as LC Classification, Dewey Decimal Classification, or NLM Classification), and at least one subject access point drawn from standard thesauri.

Cooperative Online Serials Program (CONSER)

CONSER is a source of high quality bibliographic records for serials and integrating resources that conform to approved standards. Unlike most monographs, serials and integrating resources are constantly changing in a variety of ways. CONSER Program participants are given the authority to modify the master serial record on the OCLC WorldCat database.

Name Authority Cooperative Program (NACO)

Through this program, participants contribute authority records for personal, corporate, and jurisdictional names; uniform titles; and series headings to the LC/NACO Authority File. Membership in NACO is open to any institution willing to support their staff through a process of training, review, and direct contributions of records to the LC/NACO Name Authority File.

Subject Authority Cooperative Program (SACO)

Subject Authority Cooperative Program (SACO) members propose subject headings for inclusion in Library of Congress Subject Headings (LCSH), and classification number proposals for inclusion in Library of Congress Classification (LCC) schedules.

PCC Training

In support of its mission and goals, the Program for Cooperative Cataloging conducts specialized training and mentoring for participants and non-members in conjunction with professional meetings and conferences, or as part of the Program itself with training held at the Library of Congress and institutions around the world. Additionally, in response to the need for general cataloger education, the PCC, the Library of Congress, and ALCTS developed several workshops now freely available through the Web at the Cataloger’s Learning Workshop (CLW). CLW workshops reinforce metadata and cataloging creation skills that ultimately improves the quality and increases the number of shared records.
