This is my first post to this list so if I'm in the wrong place, please
point me in the right direction.

I'm trying to implement 007 tag functionality in my automation software but
the definition for 007 tags is somewhat ambiguous and I'm having a hard time
determining the definitive source for "category of material" within the
context of the type of record or material type.  For instance, with 006 tags
I know that I use '006-Books' for all material forms A and T.  I don't see
any such direction in the Marc 21 standard for 007.

The direct question: "What do I base the interpretation (or presentation) of
"Category of Material" on or is this something the end user needs to do for
themselves and I should trust their correctness?"
