    Question

    What are the Headings Change Queue tables.

    Answer

    There are three tables related to changed headings:

    1. The HEADING_CHANGE_QUEUE table identifies authority records whose 1XX fields have changed.  This table is the entry point to use when searching for information about changed headings.  For each authority record whose heading has changed, there is one entry in this table for each of the authority record’s entries in the HEADING table. This table is populated automatically when applicable changes are made to authority records.

    In other words, this table has a row for each entry in the change queue.1

    1. The HEADING_CHANGE_FIELDS table has a row for each BIB record to be changed. This table is populated by running Catjob 12
       
    2. The HEADING_CHANGE table links HEADING_CHANGE_FIELDS and HEADING_CHANGE_QUEUE. This table is populated by running Catjob 11.

     

    1In some situations the data in the tables will not correctly reflect the what appears in the Cataloging Client's Global Headings Change Queue.  These "orphan Rows" in one or more of the tables will not appear in the change queue. Contact Support to have "orphan rows" removed from the tables.
