Following up on some earlier United Kingdom (UK)-related posts here  — Digital Britain — UK Government’s Strategic Vision (June 18, 2009) and British Library Warning as to Potential for Loss of United Kingdom’s Online/Web Heritage (February 25, 2010) – according to the Open Knowledge Foundation — the British Library is at a watershed in terms of open access (OA) bibliographic data:

Milestone for Open Bibliographic Data: British Library Release 3 Million Records

This is apparently the first substantial corpus of bibliographic data to be released in an open form by a national library.

The data — i.e., the entire British National Bibliography — is reportedly also available in searchable form at Bibliographica.
