Karen, we're just getting started defining subtypes; Dissertation was just the first one we started trying to model, realizing that it had properties not likely to belong to any other "type" of Work.  We can  see that there may be lots of them, but agreeing on them will take some work.

The dissertation type is interesting, thanks, Jason. It basically takes what WAS a note that essentially changed the meaning of the entire record and makes dissertation a type of resource. [1] That is great to see. I note that there are two "sub-types" under Work [2]: dissertation and cartographic. I would have bet that music would end up there, but it isn't. Not to mention serials and seriality. We can take bets on which types move out of Work and become subtypes :-). And I can see what you mean about scaling.


[1] I also was wrong about their not being a fixed field: there is a code for theses. I believe the difficulty in my institution was that the code was filled in less often than the note was created. Probably not uncommon.
