Best used books Denver 2000 - The Book Stack, Mary Reed Building on the DU campus
2199 S. University Blvd.
Denver, CO 80210
Bookworms are always looking for a new place to gnaw, and the Book Stack, run by DU's Women's Library Association for the benefit of that school's venerable Penrose Library, is a great place to dig in. It's a repository of cheap, cast-off books: hardbacks, paperbacks, children's books, collectibles and more, some of which have already been dog-eared, and others that are just waiting to have their pages ruffled. Open Wednesdays from 9 to noon and Saturdays from 10 to 2, the volunteer-managed store isn't the biggest or snootiest used bookstore around, but it's certainly one of the nicest.
