First published online in 2010, Resource Description and Access (RDA) succeeded the Anglo-American Cataloguing Rules (AACR2) as the modern cataloging standard for libraries. The structure of the RDA represents a fundamental shift toward the digital environment, basing its framework on a relational entity-relationship model to describe resources more flexibly and comprehensively for online users.

According to the New Mexico State Library, Resource Description and Access (RDA) is a content standard, not a data value standard. This distinction is crucial for understanding its role in descriptive cataloging within the modern digital environment.
