Metadata for Libraries and Aggregators

Metadata feeds

DOAB enables libraries and aggregators to use the metadata of all available titles in the Directory of Open Access Books. The metadata is available in the following formats:

Due to technical issues, the following formats are temporarily unavailable:

  • [ONIX (3.0) – XML]
  • [MARCXML – based on the MARC 21 XML Schema, can be converted easily using MARCEdit]
  • [RIS – Research Information Systems]

MARC21 metadata provided by Penn State University Libraries

Penn State University Libraries provides MARC21 records created from metadata supplied by DOAB. There are three files:

  • CC-licenced titles
  • “Free-to-read” titles
  • Titles where only a limited number of chapters are available in DOAB

Selective Export

It is also possible to make use of our ‘Selective Export’ functionality. This enables you to export metadata in a flexible way: first by selecting the relevant titles and secondly by choosing the export format. The selective export functionality makes it easier for specialist libraries, subject repositories and frequent users to only retrieve specified subsets of open access books according to their preferences - for instance by publisher or subject field. Please be aware that this export function is optimised for sets up to 500 titles. More information can be found here
