Collection metadata services
We offer a range of metadata services to libraries, publishers, researchers and the cultural heritage sector.
The British National Bibliography (BNB)
The British National Bibliography (BNB) records the publishing activity of the United Kingdom and the Republic of Ireland since 1950.
The BNB is currently available on the Share Family beta portal. It is published as linked data as part of an international collaboration of libraries to enhance discovery.
To request a Catalogue-in-Publication (CIP) record, please contact Bibliographic Data Services (BDS).
To request a weekly PDF of new additions to the BNB, please contact us at metadata@bl.uk.
