RDA Explained for Library Cataloguing

In the world of libraries and information management, the acronym RDA plays a significant role. It refers to a specific set of cataloguing rules used to create metadata descriptions of resources.

Understanding RDA: Resource Description and Access

The acronym RDA stands for Resource Description and Access. This is the current cataloguing standard adopted by many libraries worldwide, succeeding the older Anglo-American Cataloguing Rules (AACR2).

Breaking Down RDA:

Let's look at what each part of the name signifies:

• Resource: This refers to any item recorded in a catalogue. It can be a book, a journal article, a map, a video, a digital file, or almost any other type of information carrier. RDA focuses on describing the resource itself.
• Description: This part highlights the core function of cataloguing – providing descriptive information about the resource. This includes details like the title, author/creator, publication information, physical characteristics, and subject matter. The goal is to identify and describe the resource accurately.
• Access: This component emphasizes how users find and utilize the resource. RDA is designed to create metadata that facilitates discovery and retrieval, supporting various user tasks like finding, identifying, selecting, and obtaining resources. It aims to make resources accessible through different means and contexts, especially in the digital environment.

Significance of RDA:

Resource Description and Access provides a framework for cataloguing that is more flexible and adaptable to the digital age compared to its predecessors. It is built upon conceptual models like FRBR (Functional Requirements for Bibliographic Records) and LRM (Library Reference Model), enabling richer descriptions and better linking of related resources. This helps users navigate and discover information more effectively in online catalogues and discovery layers.

Therefore, when encountering RDA in library cataloguing, remember it stands for the internationally recognized standard focusing on describing resources and enabling user access to them.
