Input Conventions

This field is typically created in an offline conversion process, when records from other external sources are integrated into the CERL Thesaurus. Thus, although manual input of this field is permitted, it will rarely be used by editors.

Records that have been created in the CERL Thesaurus usually do not have a field 801, unless they have been merged to existing records from other source files. This field should only be used to indicate that a record from an external file is the source or one of the sources for the given record. It should not be used to indicate that an external record describe the same entity or resource as the given record.

If a source fiele does not provied a date of last change, the data of data delivery is used in subfield $c.
