some textbooks do include the new DSM 5 classifications/diagnostics and information. the DSM 5 was in the works for many years and the authors of these texts books purposely left space available for its inclusion. that way once the DSM 5 was completed and ready for use all that was needed was to copy those pages that were needed in the texts, and paste them to the right blank pages. things are not so complicated now that we have computer programs like microsoft office or other word processing programs, where its easy to edit, change things with just a click of a key command on the computer. what used to take many months to do can now be accomplished in just a few minutes to a few hours depending upon what the editing process is.
