When field 263 is present, Leader/17 (Encoding level) contains value 8 (Prepublication level). Used for works that have not yet been published but which have been cataloged as part of a cataloging-in-publication (CIP) program or similar programs that create prepublication records, such as the U.S. ISSN national center program.
