The Coop Team are receiving requests to clarify the size of the name authority file.
The LC/NAF as a whole totals about 5.5 million name authority records. The subset of records contributed by NACO members is about 2.3 million name authority records.
These numbers are separate from the subject authority file (LCSH). At the end of fiscal year 2004, that file contained 283,500 records.
