Backlist
All available books or music titles from a publisher that have not appeared new are referred to as the backlist .
A good backlist consists mostly of titles that are still easy to sell and thus forms the economic backbone of a publisher . These works only incur reprinting costs, which means that they are usually more profitable than new publications, which almost always have high development and initial costs. Building a sellable backlist is the goal of every publisher.
Notwithstanding the above definition, some publishers also use the term for all available books, including new publications.
