    How does Voyager index the call number?


    The mfhd’s 852, indicator 1 determines the classification scheme and indexing/sorting rules. For example, if the first indicator of the 852 is 0 and follows LC Call Number rules, it will be indexed as such in the database.  If the call number cannot be parsed as an LC number, it will be stored as an “other” type call number in the database (the coding in the indicator will be left as is in the MARC record).

    Data from the CALL_NO_TYPE table in the Voyager database:

    If you do a Mfhd Call Number search set as Find for PR9199.3?, the system will bring up all records indexed beginning with PR9199.3:

    Data from the MFHD_MASTER Table (where the call number is indexed):

    MFHD from Cataloging

    The first indicator is set to 0 for LC.  The call number entered in the h and i follows the LC Classification scheme.  Thus, it is indexed as an LC Call Number in the database.
