If a change is made to a Library of Congress subject heading in a bibliographic record, will the corresponding FAST heading be corrected via automation?


A monthly process monitors additions or changes to LCSH and makes applicable changes to FAST headings. Because of this, catalogers do not need to edit FAST headings when they change LCSH.

Please note that if a cataloger would like to change the FAST headings, this is okay, and the monthly process will look at those changes, updating or correcting the FAST headings as necessary. However, with cataloger entered changes, no attempt will be made to synchronize the LCSH and FAST headings.
