The International Standard Bibliographic Description (ISBD) is a set of rules produced by the International Federation of Library Associations and Institutions (IFLA) to create a bibliographic description in a standard, human-readable form, especially for use in a bibliography or a library catalog. A preliminary consolidated edition of the ISBD was published in 2007 and the consolidated edition was published in 2011, superseding earlier separate ISBDs for monographs, older monographic publications, cartographic materials, serials and other continuing resources, electronic resources, non-book materials, and printed music. In 2022, IFLA published the 2021 update to the 2011 consolidated edition, which includes expanding ISBD to include unpublished resources, integrating stipulations for the application of ISBD to the description of component parts, clarifying cartographic resources stipulations, as well as added examples and updates to the Areas and glossary sections. IFLA's ISBD Review Group is responsible for maintaining the ISBD.

One of the original purposes of the ISBD was to provide a standard form of bibliographic description that could be used to exchange records internationally. This would support IFLA's Universal Bibliographic Control program.
