An out-of-print (OOP) or out-of-commerce item or work is something that is no longer being published. The term applies to all types of printed matter, visual media, sound recordings, and video recordings. An out-of-print book is a book that is no longer being published. The term can apply to specific editions of more popular works, which may then go in and out of print repeatedly, or to the sole printed edition of a work, which is not picked up again by any future publishers for reprint.
