<p>I live at the Sem Coop - when I am not at the Reg. And I, too, have bought many Greek books there! It really is a wonderful place, and, in addition to all of the books mackinaw mentioned, they also have quite an extensive collection of books written by U. of C. professors and people related with the U. of C. My family has a membership, and, although I rarely buy anything there, I do like to just browse and read.</p>
<p>You also might want to check out the University of Chicago Bookstore (not to be confused with the Seminary Coop Bookstore), where, besides books, they have quite a lot of UC clothing on the second floor.</p>
