Module 21.10. Revising AACR2 records to "back-up" the description

Changes in serials can also be discovered retrospectively when earlier issues are reviewed. AACR2 requires that the record be based on the earliest issue available which may be far removed from the first issue published. CEG B4.3.4 states, "when an AACR2 record contains a ‘Description based on’ note and a CONSER member has the first issue in hand, the member ‘backs-up’ the record to reflect the first issue and deletes the ‘Description based on’ note." This is done when the cataloger has the first issue in hand. The record may also be "backed-up," with an earlier issue recorded in the "Description based on" note, when the earlier issue results in different information in the body of the record (title, edition, designation, publisher). (See example below). It is generally not necessary to "back-up" the description simply to record an earlier issue in the "Description based on" note.

When reviewing back issues, if it is discovered that a minor title change occurred, modify the title proper to reflect the earliest available issue and record the previous title proper as a variant title. (See also CCM 7.3.)

Uniform titles may also be modified when "backing-up" serial records. If the place of publication is changed to reflect an earlier issue and the uniform title is qualified by place name, also change the qualifier in the 130 field to match the place name in the 260 field (see example below).
