Introduction

Classification Scheme Sources contains a list of classification schemes and assigns a code to each scheme.  The purpose of this list is to enable the scheme of classification number(s) contained in metadata records to be identified by a code.  For code assignment, general structure, usage, and maintenance guidelines see Introduction.

Note:  The caption and index terms from the following classification schemes may be used as a source of controlled subject terms in bibliographic records by some institutions.  Thus the sources assigned source codes in this list may also be used in usage elements identified for subjects in Subject Heading and Term Source Codes, if appropriate.

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 characters, including lowercase alphabetic characters, numeric characters 0 through 9, and the hyphen (-).  Possible additions to codes are described in Source Code Maintenance.

For many classification schemes of states of the United States, the source code consists of the U.S. Postal Service abbreviation for the state as the first two characters, followed by other letters identifying the specific scheme.  For government document classification schemes, "docs" follows the first two characters.  For other sources, the entire code may be based on the title of the documentation or scheme.
