RDA Exceptions

Resource Description and Access (RDA) Exceptions

RDA EXCEPTIONS

In Resource Description and Access (RDA) cataloging rules there are a number of guidelines and instructions that are labeled as exceptions. Some instructions are scoped as being applicable only to certain types of resources (such as serials). An exception is an instruction that takes precedence over the immediately preceding instruction and applies to a specific type of resource, condition, etc. Here in RDA Toolkit, a LC-PCC PS appears which suggests the LC practice is to apply the guidelines in Descriptive Cataloging of Rare Materials (Books) (DCRM(B)) for books published before 1801 and selected early 19th century resources instead of RDA rules. Unlike alternatives and options, exceptions are not subordinate to general instructions, therefore, RDA exceptions generally do not require policy statements, although some exceptional situations may require some additional considerations. Exceptions must be followed when applicable. They are provided when it is necessary to depart from a rule’s instructions because of a specific type of resource or situation.


Example of RDA Exceptions 

RDA rule 2.3.2.5 is for Title in More Than One Form. After the instructions and example, an exception to this rules appears as for Serials and integrating resources, which suggests “If the title of a serial or integrating resource appears on the source of information for the title proper in full as well as in the form of an acronym or initialism, choose the full form as the title proper.” (Click on the image to enlarge)

Alternatives Options and Exceptions in RDA : What Every Cataloger Needs to Know

RDA contains a number of guidelines and instructions that are marked as alternatives, options (optional additions, optional omissions), and exceptions. Each of these is clearly identified by an italicized label, which in the RDA Toolkit appears in green color in the instruction (alternative, optional addition, optional omission, exception). A green vertical bar also appears in the left margin next of an alternative, optional, or exceptional instruction in RDA Toolkit. These allow individual libraries or cataloging agencies to make decisions based on individual considerations in cases where two or more provisions are equally valid. Guidelines for alternatives and options are provided in RDA rule 0.8, and instructions for applying exceptions is at RDA 0.9 of chapter 0. 

How to decide whether to apply the alternatives, options, or exceptions?

Whether to apply the alternatives, options, or exceptions is cataloger judgment, unless an LC practice has been identified in an LC-PCC PS (for LC catalogers). Each library or cataloging agency must decide whether or not to use each of these alternatives and options. This can be done by choosing one or more of the following approaches: (a) Establishing local policies for all options and alternatives, or (b) Establishing local policies for some, but not all, options and alternatives, or (c) Following the policy statements of other libraries and programs, such as the Library of Congress-Program for Cooperative Cataloging Policy Statements (LC-PCC PS) or British Library Policy Statements (BL PS), or (d) Allowing individual catalogers to use their judgement who are responsible for creating the metadata for the bibliographic items.

Unlike alternatives and options, exceptions are not subordinate to general instructions, therefore, RDA exceptions generally do not require policy statements, although some exceptional situations may require some additional clarification. Exceptions must be followed when applicable. They are provided when it is necessary to depart from a rule’s instructions because of a specific type of resource or situation.
