Changes

'''LC''' usage follows '''NACO/SACO''' usage sections. The LC usage section is also divided into subsections on Name/Series usage, and Subject usage, as appropriate. Some LC usage may be more restrictive than that prescribed for NACO and SACO participants. NACO and SACO participants may not be restricted necessarily from using specific data elements even though LC does not use them. These differences are noted when they occur. Instructions for genre/form terms and medium of performance terms fields and subfields are given in the SACO and LC Subjects usage sections. ''Note:'' As of June 1, 2006 LC does not create or update SARs.
