The updated e-manuals of UNIMARC/B and UNIMARC/A have been published, both version 1.1.0 (2024). The scope of updates and corrections is detailed in the “editing history lists.”

The first version of the online edition of the UNIMARC Authorities Format Manual was published in 2023, replacing previous editions. It includes changes agreed upon by the UNIMARC Permanent Committee (PUC) from 2010 to 2023. This edition also includes corrections in the text and examples, a reorganisation of the appendices and a new manual structure (tables of subfields, occurrence, repeatability, history paragraphs). The new UNIMARC Authorities Format documentation is an online integrated resource intended to be a permanently complete documentation and usually updated once a year.

The UNIMARC bibliographic format is the backbone of a set of standards for the representation and exchange of different library data records: bibliographic, authorities, classification and holdings. Where applicable references are made to these formats but no details are given. For that, users of the bibliographic format are referred to the documentation for those formats. The UNIMARC Bibliographic format is designed to be a carrier for bibliographic information. It covers monographs, continuing resources, cartographic resources, music, sound recordings, graphics, projection and video materials, rare books and archival resources and electronic resources. This Manual is both a definitive statement of the bibliographic format and a guide to its use.
