Sometimes your professors will put books on reserve so that all of your classmates can share it, and no one person gets to hold onto it for too long. While the spirit of sharing is a wonderful thing, it can be annoying to trek all the way to the library to see if that reserve book is available or being used.
Fret no more! Just go online in the comfort of your dorm and type in your professor's name to check the availability of reserve items. Of course, there's no guarantee that it won't get checked out while you're on the way over - but you'll definitely know when not to bother.
