Mdhatter: MIT students are notoriously dismissive of Harvard students, as well. One could imagine, for example, creating a database of courses (easy: there's a course catalog), loading that into a portable tablet PC, and then scanning books at extremely high speed as the tablet PC prompts for the next course. You'd be done in no time, as opposed to lurking for hours.

Note that MIT has a similar cozy arrangement with the Tech Coop, but I'm not aware of any efforts by students there to break this monopoly. So I give the nod to the Harvard students, low tech data collection or not.
