William, I'm not quite sure what your "at a minimum" represents, so  
this answer may or may not fit your use case.... however, MARC doesn't  
actually have required fields, but most systems do make a small set  
mandatory. Most of the required ones are in the 00X range, and many of  
those are administrative data. Of the variable fields, the only one  
that I have seen as mandatory is the title (245). That would be the  
manifestation title.

In case you haven't seen this, there are statistics on the actual  
field usage at:

I also want to note that some of the more useful data comes out of the  
Leader and the 008 fields (resource type, date of publication,  
language).
