The Old Book Barn is the place to go in the Decatur area for used books. They have thousands of book in a wide variety of genres. They also carry some new books as well as a few other non-book items. They are well known for their ghosts and spirts section which holds a vast assortment of books on this subject. Their prices are very reasonable. I've purchased cookbooks, children's books, sheet music and general fiction books from this store and been very pleased with my purchases. They also have a trade-in program that I have not taken advantage of because it doesn't seem to be a great deal. The staff is also very helpful in assiting you in looking for a specific book.
