21.2.  Updating bibliographic information

21.2.1.  Changes that may require a new record

A variety of changes may occur in a serial publication that lead to the creation of a new record.  CCM Module 16, “Changes That May Require a New Record,” covers situations in which the cataloger must determine whether or not a new record should be created.  Major and minor title changes according to AACR2 21.2C2 are explained in CCM 16.2.3 and 16.2.4 with instructions on modifying existing records to reflect  minor changes.  New records are not required in such cases.  The table below lists the types of changes that may require a new record, and the related documentation.

21.2.2.  Changes affecting other access points

CONSER maintenance requirements primarily cover changes affecting main entry, title proper, and other access points (CCM 21.1.4, CEG B4 ).  Part 1 of the CCM covers most of these changes, including how they are reflected in the record.  The table below lists the areas in which changes occur and the corresponding section in the CCM.

21.2.3.  Other changes to the bibliographic description

Other changes to the record that do not affect record access are generally considered optional, with one exception:  frequency data in the fixed field (CEG B4.2.3 ; Section E, 008/006, Frequency/Regularity ).  As with changes to access fields, changes to fields that are used in the description of the serial are generally covered in Part 1 of the CCM and usually involve the addition of notes.  CCM 3.4, "Transcribing Information from Later Issues," gives general information about changes that involve the addition of notes to the record and changes that can be made to the body of the record.  The sections listed below give specific instructions on adding descriptive information to serial records.
