Introduction

Function Term Sources contains a list of sources of codes and/or terms used to specify the function or activity that generated the materials described in the bibliographic record and assigns a code to each source. The purpose of this list is to identify the vocabulary used in records.  For code assignment, general structure, usage, and maintenance guidelines see Source Codes for Vocabularies, Rules, and Schemes.

Many general subject lists and thesauri also contain controlled vocabularies for specifying functions.  Thus those general sources may also be used in usage elements identified for function terms, with the appropriate source code (see Subject Heading and Term Source Codes).  Only sources that are specific for functions 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 Codes.
