The new RDA is the next step in development for a metadata standard for the 21st century.

RDA: What You Need To Know


Guide to RDA: Resource Description and Access

RDA: Resource Description and Access is a content standard providing guidelines and instructions for creating library and cultural heritage bibliographic metadata.

It is a web-based tool that was created and developed by the RDA Steering Committee for the digital era to replace the Anglo-American Cataloguing Rules (AACR).


Why do we need RDA?

Metadata creation and management is vital to managing resource discovery for both librarians and library users. The AACR was a previous set of metadata rules that were initially designed for printed card catalogues, but as libraries and their catalogues have progressed into the digital age these rules became less relevant.

As a web-based tool, RDA addresses the cataloguing needs for all types of content and media.

Committee Matters - Blog Post

We give our time and knowledge to serve on committees, and we know it is a “good thing” for us to do. We don’t talk so much about what serving on committees gives back to the individual committee members, but it is not a selfless act.
