Galapagos Islands v Maps, Topographic. The basic differences between the proposed core level and the full level records are that all notes fields are eliminated, nearly all coded information is eliminated, most mathematical data are omitted, added entries are not included and redundancy in the record is reduced dramatically. Subject access in the core record may be given fully, as is shown here, or it could be reduced to a minimum of one heading. Until the map core record task force issues a standard format, records using the format proposed here could be input into OCLC as K level records or they could be created for local use only. Cataloging for maps requires advanced cataloging ability as well as knowledge of technical map features and mathematical data.
Geographic literacy is also requisite.
However, core level records do not contain detailed information about projection, coordinates or relief methods used. Full level map records are usually long and can contain many notes. Creating and revising a full level map record can take two or more hours. Based on preliminary work, it is estimated that core level map records may only take 30 minutes to complete. This allows time for other projects or additional map cataloging.
