E2.1.

The default approach presented above is not prescriptive and indeed may not be desirable in every situation.  Institutions may sometimes want to create separate records for different impressions or for other bibliographic variants.  Some may want to create separate records for each individual copy.

LC Rare Book Team Guidelines:  Generally follow DCRM(B) by cataloging at the edition level with exceptions per cataloger’s judgment or based on a collection-wide (processing plan) decision.

E2.2.

Numerous factors will influence the decision of when to create separate bibliographic records for variants, including:

the comprehensiveness of an institution’s collections

the perceived needs of the users of these collections

whether and how the publication has been described in a standard bibliography

whether the publication can be compared to other copies

the desire for consistency with other records in the institution’s catalog

the quality of the records available for use in copy cataloging

the structure of any shared database to which an institution contributes its records

the nature of an institution’s policies, priorities, and staffing levels

E2.3.

Within the rules, alternatives are provided that allow a cataloger to create separate records for individual impressions, states, binding variants, or copies (see rules 2B3.2, 2B4.2, 2D2, 4G).  The cataloger must be consistent in applying these alternative rules to all areas of the description once the decision has been made to apply them.
