PCC guidelines for coding MARC 21 264 field are available from: http://www.loc.gov/aba/pcc/documents/264-Guidelines.doc The guidelines were developed with the help of staff from the Library of Congress Policy and Standards Division and other stakeholders.
It should be noted that these guidelines do not address the application of the 264 field for materials cataloged under the standards for Descriptive Cataloging of Rare Materials (DCRM) or other standards for specialized materials. The communities working on the application of RDA for specialized materials will need to develop appropriate guidelines for using the 264 field with those materials.
