The Seminary Coop is located across the street from the University of Chicago main quadrangle. It's loosely affiliated with the school - a large part of their business comes from selling books for classes - but it is by no means a 'school bookstore'. The Seminary Coop's business is about serious scholarly books in the humanities and social sciences. They have a vast selection available for browsing and if you're visiting the University, I highly recommend dropping in if you have any interests along those lines.
