MARC21-008: Type of date or publication status
actual date and copyright date [obsolete]
c
continuing resource ceased publication
d
New issues of a continuing resource have ceased to be published or that a change in author or title has caused a successive entry record to be created. When a new title supersedes a previously existing one, the earlier title is considered dead and coded d in field 008/06. An item is considered to have ceased publication only when there is clear evidence that it has. Generally, a period of more than three years during which no new issue of a continuing resource has been published is considered evidence that it has ceased publication.
continuing resource status unknown
Used for continuing resources when there is no clear indication that publication of the item has ceased. A beginning date of publication; and the characters uuuu since no ending date is known.
u
date of distribution or release or issue and production or recording session when different
Both a date of distribution/release/issue (008/07-10) and a date of production/recording (008/11-14) are present because there is a difference between the two dates. For computer files, code p is used when there is a difference between the date the file first became operational for analysis and processing in machine-readable form (i.e., production date) and the date the file became available to the public, usually through an established agency (i.e., distribution date). For moving images, if a work with identical content but in a different medium has a later release date than the original work, code p is used (e.g., a videorecording released in 1978 that was originally produced as a motion picture in 1965).
