E/F postfixEdit

Hello, as I understand 'E' or 'F' postfix mean language, English or French. ID without this postfix points to the same record. I have planes to remove this postfix from all items. Is there some opposition? — Ivan A. Krestinin (talk) 18:22, 8 March 2015 (UTC)

  DoneIvan A. Krestinin (talk) 19:57, 9 March 2015 (UTC)
If this was removed back in 2015, why is [EF] still part of the constraint? I'm trying to add 0017B9238‏ for Edward Kruk, and I get an error. Also, the link it generates isn't correct, with or without an E at the end. Nick Number (talk) 15:36, 13 February 2019 (UTC)

Allowed valuesEdit

According to there's an optional hyphen around the central [A-Z], so shouldn't the allowed values read as \d\d\d\d[A-Z,\-A-Z\-]\d\d\d\d instead? LeadSongDog (talk) 15:30, 4 October 2016 (UTC)

No. Otherwise this would complicate matching identifiers for distinct value constraints or finding existing items with a given value.

It can finish by a characterEdit

Hello, somme reference finish by a character. Ex : 1001C8015e 1001C8015e. Please, update the model. Thanks, --Bergil (talk) 08:31, 6 February 2018 (UTC)

Records that don't exist without 'E' or 'F' appendedEdit

There are instances where dropping the closing 'E' or 'F' (English/French) indicator does not seem to work. Please see:


How should these record(s) be recorded? Thank you-- TimK MSI (talk) 10:38, 30 October 2018 (UTC)

Important changeEdit

Notice on the website

"Library and Archives Canada (LAC) will no longer be updating the Canadiana Name Authorities Search; however, the site will continue to be searchable until March 2019. LAC stopped creating new authorities in AMICUS in September 2018 and will resume creating new authorities in OCLC’s integrated library management system, WorldShare Management Services (WMS), in late fall or early winter. English-language authority records will be created in the Name Authority Cooperative Program (NACO) file, and French-language authorities will be created in a separate file."

And more details FAQ :

"While many organizations around the world maintain French-language authority files, there is currently no international shared French-language authority program comparable to what is available in English through NACO. For this reason, LAC has now begun to maintain its separate French-language name authority file using the WMS Canadiana Name Authorities in French functionality. LAC’s French-language authority data will continue to be freely accessible at"

That means, NONE LAC-ID is useful at this time, and nobody knows, if or when this will change and the system can be accessed again. Eisbaer44 (talk) 07:12, 28 August 2019 (UTC)
