Resource Description and Access

Resource Description and Access (RDA) is the successor to Anglo-American Cataloguing Rules (AACR) for library cataloguing, designed to bring the old-fashioned rules designed for paper card catalogs into the digital age. Data no longer has the strict size limitations of physical cards, and many of the cryptic abbreviations have been dropped in favor of more readable full descriptions.
