This paperback copy of the DSM-5 by the American Psychiatric Association is still sealed in its original plastic. However, since there are some slight imperfections at the corners where the plastic has started coming off, I am calling the condition excellent instead of like new and discounting it to reflect these minor flaws (see photos). ISBN 978-0-89042-555-8 (Note: The version I am selling is the DSM-5 which was published in 2013. There is a newer version called the DSM-5-TR which was published more recently, so make sure you get the version you are looking for)!
