Guidelines for LC Call Numbers
Classify items according to the LC classification schedules, unless one or more of the exceptional cases listed in LTS Procedure 11#11, "Shelflisting," apply. Use the schedules on the Catalogers Desktop. Add the call number to the bib record in the 050 field, 1st indicator blank, and 2nd indicator 4 (050: 4:).
If you find an actual LC cutter for an individual literary author, artist, geographic area, or subject, use it. Otherwise construct a cutter using Library of Congress practice for cuttering, as described in the LC Shelflisting Manual, available on Cataloger's Desktop.

Guidelines for Access Points
...
Starting on December 1, 2014, LTS exclusively uses FAST subject headings on minimal level records. This change applies to minimal level (that is, encoding level 7) cataloging only and not to class-on-receipt (encoding level 3) or full cataloging.
Consult LTS Procedure #127, FAST Headings for Cataloging, http://lts.library.cornell.edu/lts/pp/cat/127FAST for guidance on the use of FAST.
