I had a program run through LC names issues 12.31 through 12.34, looking for the first appearance of each distinct 010 $a that contains the 667 field added during phase 1. The program found 436,943 such records: that then is the number of records updated by program during phase 1. Here are distributions of the records in a few different ways:
Distribution by 1XX tag:
Distribution by rules code (008/10):
Distribution by series type (008/12):
The records with 008/10'z' were--at the time the program was run--not coded correctly (no 040 $e), and so were not recognized as RDA records; these records have since been corrected, and the 667 removed. Which leads me to point out that adjustments continue to be made both one record at a time and by program to records in the LC/NACO Authority File. For example, several thousand records with 008/10='a' created 2000- have just been re-coded by program as AACR2, and the 667 field removed. Such adjustments are not reflected in the above counts.
If anyone is interested in making further analysis of the records changed during phase 1, I can offer a raw data file on which such analysis might be based.
