Appendix E. Content Designation

Content designation is the labeling or coding of bibliographic data to identify each character string to facilitate machine manipulation and indexing in an automated environment. The labels or tags included here are those most frequently used in processing bibliographic records for non-book cartographic items. Additionally, in many cases only the most commonly used subfields and/or indicator values are listed. Subfield codes are generally listed in alphabetical order that does not necessarily reflect the order used in bibliographic records. Information for additional tags, indicators, and subfield codes can be found in MARC Conversion Manual: Maps (1984) and MARC 21 Format for Bibliographic Data (1999).

The arrangement of the individual tags is based on the sort order defined in the application for the LC Maps database. For tags that can occur in "blocks" of fields (i.e., 5xx, 6xx, 7xx, and 8xx) the tags are listed numerically.
