What is rda in library science?

RDA, or Resource Description and Access, is a set of guidelines and standards for cataloging library materials. It was developed to replace the Anglo-American Cataloguing Rules (AACR) and is designed to be more flexible and applicable to a wide range of resources, including digital content. RDA emphasizes the importance of user needs and provides a framework for describing resources in a way that enhances discoverability and access. It supports linked data principles and aims to facilitate interoperability in the global information environment.
