Can you buy books at the commissary?

No, you have to buy books from the publisher. There are also books available in the institution's library. [Amazon](http://www.amazon.com/b/ref=as_sl_pc_tf_lc?node=283155&tag=inmatecom-20&camp=15329&creative=394453&linkCode=ur1&adid=1NK4T3Z8XDKYJ0S12D53&&ref-refURL=https%3A%2F%2Fwww.inmateaid.com%2Fpages%2Fdetails%2Fsend-books-to-an-inmate-in-prison-or-jail) is one of the most reliable companies that may deliver books to inmates. You have to enter the inmate's name, ID number and the correct address of the facility. You have to buy "new paperback books", the used books are sold by third party affiliates and those books will get rejected. There are no other tricks to it, other than staying away from the other book sellers on the Amazon site that sell used books.
