Subdivision Authority
Records
LC has begun
creating machine-readable authority records for topical, form, geographic,
and chronological subdivisions. The project is not yet complete.
Catalogers will find subdivision authority
records in Orbis LTLC and in the RLIN SAF file (the same commands used
for subject heading searches are used for subdivision searches).
Catalogers will not find subdivision
authority records in Orbis LTYL and will not be able to derive them into
LTYL at this time.
Here is an example of a form subdivision
authority record (185):
010: : |a sh 99001417
040: : |a IEN |b eng |c DLC
073: : |a H 1095 |z lcsh
185:
: |v Software
680/1: : |i Use as a form subdivision
under topical headings for computer programs that are tools to perform
tasks, for example, systems software, utilities, or applications programs.
681/1: : |i Reference under the
heading |a Computer software
