Canadian Subject Headings (CSH)

Table of contents

As of April 2019, Library and Archives Canada (LAC) maintains CSH from within OCLC’s integrated library management system, WorldShare Management Services (WMS).

LAC no longer maintains a separate search site for CSH, but makes copies of the complete CSH file in MARC21 freely available through FTP to libraries and other organizations to load into their own systems. More information.

CSH is a list of subject headings in the English language, using controlled vocabulary, to access and express the subject content of documents on Canada and Canadian topics.​

Suggestions for new headings or changes to headings and comments

Suggestions for new headings or changes to headings are welcomed by LAC. No special proposal form is required. Please send suggestions or questions about CSH to:
