Backlist
（重定向自Frontlist）
A backlist is a list of older books available from a publisher, as opposed to titles newly published (sometimes called the frontlist).
Building a strong backlist has traditionally been seen as the way to produce a profitable publishing house, as the most expensive aspects of the publishing process have already been paid for and the only remaining expenses are reproduction costs and author royalty. A strong backlist is also a form of The Long Tail in modern business plans.
