Library and Archives Canada signs agreement with OCLC

(March 2017) Library and Archives Canada (LAC) is pleased to announce that it has signed an agreement to replace AMICUS and the National Union Catalogue with OCLC services. This transition will occur over the next 24 months, and should be completed in 2019. 

Please note that the current interface will remain operational until the transition to OCLC is complete. LAC will inform you about any major changes to the interface.

About the National Union Catalogue

The National Union Catalogue in AMICUS contains bibliographic descriptions, location and holdings information for continuing resources and monographs, in all subject areas, held in more than one thousand Canadian libraries. Included are: computer files, maps, microforms, newspapers and works in special format (braille, large print, talking books, described videos, captioned videos) for persons who are print or hearing-impaired.

Contributing to the National Union Catalogue

There are two methods of contributing records to the National Union Catalogue: MARA, and Update Locations. Both services are free of charge.

Machine Readable Accessions (MARA)

Libraries that are able to send their records electronically in MARC format should send their records to the National Union Catalogue using the available MARA service.

Update Locations on AMICUS Web

Libraries that cannot send their records electronically in MARC format should use the Update Locations service offered by the National Union Catalogue.

This function allows libraries to add, revise, or delete their own holdings in AMICUS Web. Libraries using this function can update holdings only; they cannot create or edit bibliographic data. If a new bibliographic record or change to bibliographic data is required, it can only be done by the National Union Catalogue.

Database Services for Clients with Disabilities

​People with print disabilities who cannot read standard print due to low vision, learning disabilities or physical disabilities that prevent them from physically holding a book, require publications in alternative formats such as braille, large print, audio and electronic text. Library and Archives Canada's (LAC) National Union Catalogue in AMICUS contains records for works in alternative formats, so that they can be located and shared across the country by interlibrary loan. This is a very important service since only a small percentage of Canadian works are available in alternative formats.

In addition, producers who create alternative format titles send bibliographic information about their intended productions to LAC, where pre-publication records are then created in AMICUS; these are called Canadian Works in Progress (CANWIP). Other producers routinely search AMICUS prior to starting production of an alternative format, in order to avoid duplication of effort that would otherwise cost millions of dollars.

Information on other LAC services to people with disabilities is available.
