Downloading LAC and Union Catalogue Records
It is possible to retrieve records from LAC's large AMICUS database, including LAC Canadiana cataloguing, Library of Congress and CONSER source files, by using AMICUS Web and Library and Archives Canada's Web service. With a free AMICUS Web account, one can search the database and download the MARC 21 records when needed.
Registered AMICUS clients can also download any of LAC's Canadian Union Catalogue records using the free AMICUS Web service.
Z39.50 Search and Download
If you have Z39.50 client software you can use LAC's large AMICUS database, including LAC's Z39.50 documentation to target the Library and Archives Canada collection or the entire AMICUS database. The Z39.50 search option allows clients to search the database and download records free of charge. Clients need to build a Z39.50 search strategy, learn the MARC 21 format where needed, and convert the records to their in-house system format where required. No LAC support is provided.
Canadian Subject Headings
This is LAC's online database of English-language subject headings on Canadian topics. Authority records for Canadian Subject Headings (CSH) are created in the AMICUS database of bibliographic data. Once a month, the CSH database, with all the new and updated headings from the past month, is reloaded in its entirety at Library and Archives Canada's website.
Répertoire de vedettes-matières (RVM)
This online database offered by Université Laval provides French language subject headings. The RVM Web site offers more information about products and prices.
