Thanks Roy.   Those are really small percentages.   Why so small?   Is the information not available?   Do the editors who input the data not have time to add it?  I'm brand new to the MARC world, so am not familiar with its culture and challenges.

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

Hi,
What percent of the total do the total occurrences represent?

And what number of unique records have a 700 with a $4 or an $e?

-Ross.

How often, on aggregate, is the 100 or 700 $4 or $e used?  Since I've parsed a lot of MARC records, I can tell you.  Not much (and the inconsistency of the $e makes this even less useful).

I can tell you exactly, as of December 1, 2012 in WorldCat:

Total number of records: 287,229,344
Total occurrences of a 700 field: 80,731,356
Total occurrences of 700 $4: 24,908,408
Total occurrences of a 700 $e: 14,117,538
