Canadian Subject Headings (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.

CSH on the Web offers:

  • free, up-to-date access to over 6000 subject authority records in the English language, providing in-depth coverage of Canadian topics, including those recently in the news. Coverage focuses on the Canadian cultural, economic, historical, literary, political and social experience
  • records displayed in both MARC 21 and thesaurus display
  • compatibility with Library of Congress Subject Headings
  • monthly updating of the database
  • access to CSH headings from their French-language equivalents in Répertoire de vedettes-matière (RVM)
  • a large number of references and scope notes and instructions, setting topics in their Canadian context
  • browsing, exact and keyword searching

Downloading of CSH records from AMICUS
