Datasets about our collections

The Library’s vast catalogue and holdings information is as much a rich data source for research as the individual items they describe.

About the collection

Bibliographic and other metadata about our collections when viewed at scale can provide great insight into the shifting trends of publication, emergence and fluctuation of social attitudes and taste, and even how research focuses have changed over time.

A range of comprehensive resources which can support your digital research can be accessed online or onsite at the British Library, St Pancras, including catalogues, metadata, archives and other records.

Please contact to discuss your research needs in depth. For standard metadata services please contact

What is available online? (beta): As part of its work to open its data to wider use, the British Library is making copies of some of its collection related datasets available for research and creative purposes. We aim to describe collections in terms of their data format (images, full text, metadata, etc), licences, temporal and geographic scope, originating purpose (e.g. specific digitisation projects or exhibitions) and collection, and related subjects or themes. This site is a 'beta', and is in the early stages of development.

British Library Collection Metadata: provides a range of services for researchers requiring bibliographic information for research at scale. This includes providing access in a variety of ways to the British National Bibliography (BNB) which has recorded the publishing activity of the United Kingdom and the Republic since 1950 and as such is the single most comprehensive listing of UK books and serials titles. 

Electronic Theses Online (EThOS): provides online access to UK doctoral theses dating as far back as the 19th century via a single web interface. Anyone may access the metadata relating to each thesis free of charge without prior permission for not-for-profit purposes.
