Working with Authority Records
Alma provides a set of authority records that are updated and maintained regularly by Ex Libris in the Community Zone (CZ). Alma maintains the following vocabularies:
* LC Subject (LCSH) – Library of Congress Subject Headings (updated weekly)
* LC Name (LCNAF) – Library of Congress Name Authority File (updated weekly)
Library of Congress Authorities are available every week and are usually uploaded by LOC every Tuesday to their ftp server. Once available the files are loaded on Thursday.
Access additional information on authorities from the Library of Congress Authorities site: authorities.loc.gov
Are authority records up to date?
Yes. Library of Congress Authorities are updated every night, Monday through Saturday. The nightly update includes records newly created and updated the previous day by LC catalogers and contributed by NACO participants. Any records deleted during the previous week are removed on a weekly basis early every Monday morning.
