OLAC (Online Audiovisual Catalogers) is a professional association focused on cataloging, metadata, and access for moving image, sound, and other audiovisual materials. Founded in the late 20th century, the organization connects practitioners across libraries, archives, and museums to improve description and discovery of audiovisual collections. OLAC interacts with major cultural heritage institutions and standards bodies to influence cataloging practice for films, broadcasts, oral histories, and sound recordings.

History

OLAC emerged amid shifts in library practice influenced by developments at Library of Congress, National Audio-Visual Conservation Center, American Library Association, British Film Institute, and British Library. Early membership drew from staff at Museum of Modern Art, Smithsonian Institution, New York Public Library, University of California, Berkeley, and Yale University. Over time OLAC engaged with international initiatives such as International Federation of Library Associations and Institutions, Joint Technical Committee 1, Office for Human Research Protections, and national programs like National Endowment for the Humanities. Prominent catalogers and archivists associated with OLAC have participated in projects linked to Academy of Motion Picture Arts and Sciences, British Film Institute National Archive, Library of Congress Packard Campus, and American Film Institute.

Mission and Activities

OLAC's mission emphasizes improving access to audiovisual heritage through standardized description and shared professional development. Members collaborate with organizations such as Society of American Archivists, Association for Recorded Sound Collections, International Association of Sound and Audiovisual Archives, European Film Gateway, and Digital Public Library of America to align practices. Activities include producing guidelines that reflect work at institutions like Museum of the Moving Image, UCLA Film & Television Archive, George Eastman Museum, and Library of Congress.

Membership and Governance

Membership comprises catalogers and metadata specialists from institutions including Princeton University, Harvard University, Columbia University, British Broadcasting Corporation, National Film Board of Canada, and Australian National Film and Sound Archive. Governance structures mirror models used by American Library Association units and Society of American Archivists sections, with elected officers and committees drawn from constituencies at University of Texas at Austin, Ohio State University, University of Minnesota, and national libraries like Bibliothèque nationale de France and Deutsche Nationalbibliothek.

Cataloging Standards and Best Practices

OLAC develops best practices informed by standards such as Resource Description and Access, MARC 21, Dublin Core, Encoded Archival Description, and protocols from International Council on Archives. Guidance addresses descriptive elements for materials held by institutions like British Library, National Archives and Records Administration, Cinematheque Française, and Hanns Eisler Hochschule für Musik. OLAC recommendations intersect with authority work at Library of Congress Name Authority File, Virtual International Authority File, and subject headings used by OCLC and WorldCat.

Publications and Resources

OLAC publishes guidelines, best-practice statements, and bibliographies used by practitioners at Yale University Library, Cornell University Library, University of Chicago Library, and regional archives such as New York State Archives. Resources reference descriptive frameworks developed in cooperation with International Federation of Film Archives, Cataloging Cultural Objects, and standards bodies including ISO. Training materials reflect collection types found at British Pathé, National Film Board of Canada, NHK Broadcasting Culture Research Institute, and university special collections.

Conferences and Workshops

OLAC sponsors sessions, workshops, and meetings at venues and events like American Library Association Annual Conference, Society of American Archivists Annual Meeting, Association for Recorded Sound Collections Conference, and gatherings hosted by Library of Congress. Workshops often cover topics showcased in collections at Museum of Modern Art, George Eastman Museum, British Film Institute, and Smithsonian Institution and involve collaborations with vendors such as OCLC and Ex Libris.

Impact and Collaborations

OLAC's influence appears in cataloging practice at major repositories including Library of Congress, British Library, National Library of Medicine, Bibliothèque nationale de France, and university special collections at University of California, Los Angeles. Collaborative projects have linked OLAC guidance with digitization efforts by National Endowment for the Humanities, Europeana, Digital Public Library of America, and institutional programs at Princeton University, Harvard Library, and Stanford University. The organization continues to shape how archivists and librarians describe audiovisual cultural heritage for platforms such as WorldCat, HathiTrust, and national discovery services.
