Backlist refers to a group of books published by an author or publisher that are not their most recent publications. These books may have been released earlier and could be out-of-print, but they are still available for sale through various channels such as used bookstores, online marketplaces, or the publisher's own backlist catalogue. The term "backlist" is also used to describe a list of titles that a bookseller has in stock and can sell to customers. In this context, it refers to all published works by an author or publisher that are not their newest releases.
