The British National Bibliography (BNB) records the publishing activity of the United Kingdom and the Republic of Ireland and has been doing so since the 1950s. This has traditionally included printed works and has recently been extended to electronic publications. The dataset includes metadata about published books, already published and forthcoming, and serials i.e. journals, periodicals, magazines, newspapers, etc.

The Linked Open BNB is a subset of the full British National Bibliography. It currently includes published books and serial publications, representing approximately 2.8 million records.
