RDA Options : Glossary of Library & Information Science

Glossary of Library & Information Science


RDA Options  In Resource Description and Access (RDA) cataloging rules there are a number of guidelines and instructions that are labeled as options. Options appear in two forms in RDA, viz. optional additions and optional omissions. The optional addition of data that supplement what is called for in the immediately preceding instruction, or the optional omission of specific data called for in the immediately preceding instruction. Hence, it can be said that optional instruction offers the opportunity to either supplement required data with additional information (metadata), or omit data from what is instructed in the preceding rules. Here it is important to note that each library or cataloging agency can decide when or whether to follow the options or just follow the rules in the immediately preceding instruction. They may choose to establish their own policies and guidelines on the application of the options or leave decisions on the use of options to the cataloger’s judgment.
