Resource Description & Access (RDA)

Several years ago the definition of $z of the 020 (International Standard Book Identifier) was expanded—it is now used for “structurally invalid” ISBNs (those that are too short, too long, wrong check digit, etc.) and also for “application invalid” ISBNs (ISBNs for a manifestation that would be described in a different bibliographic record). The LC-PCC Policy Statement for 2.15.1.7 provides the following instruction:   Record ISBNs in $z (Canceled/invalid) of MARC field 020 if they clearly represent a different manifestation from the resource being cataloged and would require a separate record (e.g., an ISBN for the large print version, e-book, or teacher’s manual on the record for a regular trade publication). If separate records would not be made (e.g., most cases where ISBNs are given for both the hardback and paperback simultaneously), or in cases of doubt, record the ISBNs in $a (International Standard Book Number) of MARC field 020 Please remember to u...

“Take What You See and Accept What You Get” This is the overriding principle of RDA concerning the transcription of data. It is consistent with the ICP “Principle of Representation” to represent the resource the way it represents itself. This is a fairly significant change from AACR2, which includes extensive rules for abbreviations, capitalization, punctuation, numerals, symbols, etc., and in some cases directs the cataloger to ‘correct’ data which is known to be wrong (e.g., typos). With RDA we generally do not alter what is on the resource when transcribing information for certain elements. This is not only to follow the principle of representation, but also for a more practical reason: to encourage re-use of found data you can copy and paste or scan or download into your description of the resource. Let’s see what this principle means for you as an LC cataloger, regarding capitalization, punctuation, and spacing.  It is critical that you understand LCPS 1.7.1 ; the...

Myth: “When I record multiple ISBNs, those for manifestations other than the manifestation I have in hand are coded ‘z’.” Reality: Incorrect.  LC-PCC PS 2.15.1.7 calls for this coding if the manifestation would be represented by a different record .  For example, LC does not routinely create separate records for paperback and hardback versions, so both 020 fields can be coded as “a” (the one for the manifestation in hand should be recorded first).
