Core level cataloging contains a complement of data elements less than that for full level cataloging but more than that for minimal level cataloging. For books, core level cataloging essentially calls for fewer notes, fewer subject headings, and fewer added entries. The emphasis is on cataloger's judgment, with the flexibility to add additional elements in particular cases. When it was developed, core level was seen as a dynamic level of cataloging, i.e., one in which particular records could be upgraded to full to meet a particular library's requirements. Core level cataloging exemplifies the traditional conventions of bibliographic control as stated for full level, with the exceptions specifically applicable to core level.
All access points are in authorized forms and supported by authority work.
For additional information, cf. LC Implementation of Core Level LC's implementation of core level is based on an experiment conducted from May-October 1996. In exercising this discretion, it is assumed that decisions to choose another mode will be based on the merit of the material being cataloged or on the prevailing interests of any particular user group or constituency that a team works with. The only materials consistently receiving full level cataloging are those designated for an LC reference assignment. LC will also continue to make use of external records for copy cataloging, including those done by PCC participants.
