Maybe DSpace is just too hard for everyone
I don't think anyone would disagree that the majority of faculty find depositing documents into DSpace to be just too darn hard. So our library long ago offered to take care of all the work associated with depositing. It turns out that it's pretty hard for us too. Good grief. Technically it's not straight forward. The whole "can I legally put it up" issue is just as confusing for us as it is for faculty. And it turns out that figuring out who the publisher is, what keywords to assign, etc. aren't trivial decisions either. Sigh.
