Last Spring, UNL librarian Richard Graham finished an online database of more than 180 comics (and growing). The collection includes standard comic books, as well as related source material about comics.
I think it's wonderful that UNL is creating this resource. Comics are a pretty important part of American culture, and they have been throughout history, so they're definitely worth some scholarly investigation. I wonder when UNL will add a course in comic books to the Schedule of Classes!
