ISBD International Standard Bibliographic Description : 2021 Update to the 2011 Consolidated Edition

IFLA International Standard Bibliographic Description (ISBD) is the standard that specifies the requirements for the description and identification of published and unpublished resources that are likely to appear in library collections. The ISBD determines the data elements to be recorded or transcribed in a specific sequence as the basis of the description of the resource being catalogued, and employs prescribed punctuation as a mean of recognizing and displaying data elements and making them understandable independently of the language of the description. The 2021 Update to the 2011 Consolidated Edition of ISBD takes into account the requests by users and their cataloguing needs since the publication of the 2011 edition. It extends the coverage of ISBD to a larger array of resources, optimizes its ability for granular description, clarifies and develops some of the elements, and brings more organization and refinements into the description of some types of resources.
