RDA: Resource, Description and Access Instructions

Designed for the digital world and an expanding universe of metadata users, RDA is the new, unified cataloguing standard - an evolution of the cataloguing principles from AACR2, with rules carried over or adapted to the RDA model. Benefits of RDA include: a structure based on the conceptual models of FRBR (functional requirements for bibliographic data) and FRAD (functional requirements for authority data) to help catalog users find the information they need more easily; a flexible framework for content description of digital resources that also serves the needs of libraries organizing traditional resources; and, a better fit with emerging database technologies, enabling institutions to introduce efficiencies in data capture and storage retrieval.
