ISBN & DOI POLICY

ISBN and Persistent Identifiers

Each published book should have appropriate bibliographic identification.

Where applicable, publications may be assigned:

• ISBN;
• DOI;
• ORCID-linked author information;
• other persistent identifiers.

Bibliographic metadata should be maintained accurately to support discovery through library catalogues, scholarly search engines, and other information systems.

OAPEN highlights the importance of persistent identifiers such as DOI and ORCID in improving scholarly metadata and discoverability.
