Introduction

Access Restriction Sources identifies the source of terms used to record access restrictions and assigns a code to each source. The purpose of this list is to enable the use of standardized terms indicating the level or type of restriction imposed on access to the resource. For code assignment, general structure, usage, and maintenance guidelines see Source Codes for Vocabularies, Rules, and Schemes.

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.
