The authority file goes global.
It was probably inevitable that there would be an attempt to create a global authority file for library bibliographic data. Any worldwide authority file would need the support of major national libraries and library organizations. We now have the first viable candidate.
The Virtual International Authority File (VIAF) is not a new service, but one that has become more prominent in recent times due to the direction of OCLC (starting in 2012) and the rise of linked data. It began as a joint project of the Library of Congress and the German National Library, then the National Library of France and OCLC, but now has a long list of contributors.
From OCLC, the VIAF service has these characteristics:
- A collaborative effort between national libraries and organizations contributing name authority files, furthering access to information
- All authority data for a given entity is linked together into a “super” authority record
- A convenient way for the library community and other agencies to repurpose bibliographic data produced by libraries serving different language communities
The VIAF combines the national authority files—which contain data such as names of authors and companies, conferences, places, and subject headings in their native languages—into a single international name authority service.
There are several benefits of a global name authority file (or service). Obviously, there is the fundamental benefit of providing uniform names for indexing and searching. With a global authority file, the connecting application, such as a discovery service, can retrieve and display names based on the language of the application’s user interface—and can switch on-the-fly. It enables the generation of “see” and “see also” links across languages. The VIAF allows developers to search and access the authority data using an API.
As mentioned at the beginning, the VIAF is one source which can be accessed via a linked data URI. Here’s an example:
label: “Wodehouse, P. G. (Pelham Grenville), 1881-1975”,
The above operation translates a Library of Congress control number for an author to the related VIAF record.
