Content & Standards

BDS metadata covers books, e-books, audio books, film, including TV on disc, available for download or streaming, music, including popular and classical titles, and video games.

Alongside a core record for each item, associated enriched content is available (see Enriched Content).

Physical Books

BDS covers all the mainstream published output from the United Kingdom and Ireland, including popular and academic titles. For information on non-UK and Irish publications contact our sales team.


BDS covers e-books for major UK publishers and covers material on major platform providers such as WF Howes/RB Digital, Overdrive and Ulverscroft.

BDS works with e-book platform providers to generate a library-specific URL that directs the user from the OPAC to the content licensed by their library.

The content of e-book records is consistent with the quality of our records for physical books.

Audio Books

BDS covers the output of all major audiobook publishers in the UK and includes audio clips and jacket images.

Music, Film and Games Titles

For libraries that maintain film, video game and music collections, BDS metadata covers material made available on disc or via download and streaming. BDS now carries descriptions for Video on Demand (VoD) titles, alongside its already extensive film clip and trailer download service.

For more information on the extensive classification of our entertainment metadata call our sales team or see our Metadata Standards and Content in the Entertainment section on this website.

Metadata Standards

Metadata standards are key to presenting consistent information that allows libraries to manage the large volume of information in their catalogues. The use of standards also ensures that your data is consistent with other organisations, important in a world where resources are shared.

BDS metadata adheres to all current library cataloguing and classification standards:

  • RDA
  • MARC21, UKMARC or UNIMARC exchange format
  • NACO authority control for contributors
  • Dewey Decimal Classification
  • Library of Congress Classification
  • Library of Congress Subject Headings
  • BIC and Thema
  • UK Standard Library Categories (UKSLC)
  • Genre headings for fiction
