LC Implementation

---

In February 1999, the Library of Congress began to:

• Code form subdivisions in bibliographic records using subfield $v

 
• Code form subdivisions in subject authority records using subfield $v

 
• Create subdivision authority records using the new 18X fields

All subdivision authority records include basic usage statements and instruction sheet numbers from the LC Subject Cataloging Manual.  Some also include cross-references.

The creation of subdivision authority records is not yet complete.
