Introduction

Accessibility Content Source Codes identifies standard code lists that specify information about modes of access to the content of a resource, including its primary mode of access and alternative mode(s) of access.  The purpose of this list is to identify the source of codes for the vocabulary used in records.  For code assignment, general structure, usage, and maintenance guidelines see Introduction.

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.
