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.

Originally published in 2010 to replace the outdated AACR2, Resource Description and Access (RDA) is a cataloging standard based on the fundamental principle of creating well-formed, interconnected data for the digital world. This shift was necessary to address the immense volume and variety of information resources now available and to meet the evolving information-seeking behaviors of users in an online environment.
