RDA Replaces GMD: Analyzing Assertion and Reason

This question evaluates the relationship between Resource Description and Access (RDA) and the older General Material Designations (GMD) used in cataloging.

Assertion (A) Analysis: RDA Replaces GMD

The assertion states that RDA replaces the General Material Designations (GMD). RDA, the current cataloging standard, indeed supersedes the use of GMDs found in earlier standards like AACR2. RDA uses different elements like content type, media type, and carrier type to describe the nature and format of a resource, offering a more granular approach than GMDs.

Therefore, Assertion (A) is true.

Reason (R) Analysis: GMD Inconsistency

The reason posits that the problem with the GMDs was inconsistent categorization. GMDs were often criticized for being too broad, ambiguous, and inconsistently applied across different cataloging contexts, leading to confusion and difficulties in searching and retrieval.

Therefore, Reason (R) is true.

Relationship Between Assertion and Reason

The inconsistencies and limitations of GMDs (Reason R) were a significant factor driving the development and adoption of RDA (Assertion A), which provides a more structured and consistent framework for describing resource types. Thus, the reason explains the assertion.

Both Assertion (A) and Reason (R) are true, and Reason (R) is a correct explanation for Assertion (A).
