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, Library and Archives Canada's Web service. With an AMICUS Web account (which is free of charge), one can search the database and download the MARC 21 records needed. For more information about AMICUS Web, please visit the Amicus Support Services at www.collectionscanada.gc.ca/amicus/006002-140-e.html

Registered AMICUS clients can also download any of LAC's Canadian Union Catalogue records using the AMICUS Web service free of charge. The service is available online at: http://amicus.collectionscanada.gc.ca/aaweb/aalogine.htm

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's large AMICUS database, including LAC support is provided.
