GPO continually reviews and updates the GPO Cataloging Guidelines. Changes may be based on revisions and additions to the national cataloging and metadata standards that GPO follows or the need to include new guidelines and/or modify existing ones as we encounter new types of Federal government information resources or cataloging and metadata situations.
The List of Major Changes to the GPO Cataloging Guidelines contains brief descriptions and details about significant modifications to the content of the guidelines. GPO will post updated lists periodically.
