Temporal Term Source Codes (388 Time Period of Creation - Authority / Bibliographic)
Introduction
Temporal Term Sources contains a list of sources of terms used to record time periods in bibliographic records and assigns a code to each source. The purpose this list is to identify the vocabulary used in records. For code assignment, general structure, usage, and maintenance guidelines see Introduction.
Note: Many general subject lists and thesauri also contain controlled vocabularies for specifying time periods. Thus those general sources may also be used in usage elements identified for temporal terms, with the appropriate source code (see Subject Heading and Term Source Codes). Only sources that are specific for time periods are listed here.
Arrangement of the list
Entries in the list are arranged in alphabetical order by the code and consist of the source code followed by the bibliographic citation for the source documentation. The citations are linked to the online source for some codes.
Code structure
Each code consists of a maximum of 12 lowercase alphabetic characters. Possible additions to codes are described in Source Code Maintenance.
No codes are defined.
