No, I don't believe there is, but something like that would be fantastic. I believe some universities in the UK publish reading lists in XML format, but I don't know of any US universities that do that.

It would certainly make this kind of citation analysis much easier and more accurate. Syllabi are tricky to work with because there's basically no standardization in how texts are referenced / assigned. Sometimes there's a full, structured bibliographic citation, but more often it's just a title / author pair, and the formatting can vary widely. It's an interesting information extraction problem.
