Content & Standards

BDS metadata covers books, e-books, Open Access English language titles, audiobooks, film, including TV on disc, download or streaming, music, including popular and classical titles, and video games.

Alongside an RDA compliant core record for each item, where applicable, associated enriched content is available (see Enriched Content).

BDS automatically creates records for all academic output from ‘core’ publishers, and selected titles from ‘non-core’ publishers. The same quality of record is created for print books, eBooks and Open Access titles. Details of the essential and discretionary fields in BDS academic records are available on request. Contact us for further information.

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. 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.

Metadata Standards

Metadata standards are key to creating high-quality records that aid users in successfully discovering resources. The use of standards also ensures that your metadata is consistent with other organisations, important in a world where resources are shared.

BDS metadata adheres to all current library cataloguing and classification standards for public and academic libraries:

  • 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

BDS keeps a watching brief on the development and adoption of FAST subject headings.
