I love the breath, width, and prices of the books and it is a great place to browse. But, looking for specific non fiction interest area is not an easy task. Non fiction books are shelved in generalized subject areas and there is no subject catalog of holdings, or classification system available to you or the clerk. Come on guys, update you records data base and improve your customer service! The Library of Congress has been providing classifying information right inside the books for about 100 years!
