Let me do this again (from scratch, even). The following are the number of records that have the listed elements, out of 289,294,984 records processed, as of 1 January 2013 in WorldCat:

700 $4: 14,229,291 or 4.92% of the total
700 $e: 9,904,536 or 3.42% of the total

My guess of the kinds of records that contain these:
- 700 $4: most are AACR(2) records for a/v and music materials?
- 700 $e: most are AACR2 or pre-AACR2 records with "ill.", "joint author". etc.?
