Advance: Money paid to an author for publication rights before the author has earned it through sales of the author's work. Advances are usually "recoupable"--to be paid back to the publisher only out of the author's earned royalties.
Advance endorsements: Endorsements obtained from experts in the field or opinion-makers before a book is published. Useful in catalog copy, sales presentation materials; and announcement ads. May also be used on book cover or jacket. (See Cover blurbs.)
Advance orders: Number of copies the publisher's sales force expects to place in stores through orders received prior to a book's publication. Same as Lay-down or Prepublication orders.
Amortization: Reducing (and eventually wiping out) expenditures and/or debts by spreading them out over a fixed period of time.
Author tour: Book promotion tour undertaken by the author.
Author's questionnaire: Request from the publisher to the author for specific items of personal information, such as education, places lived, other books or articles published, and so on. To be used to shape the marketing and packaging of a book.
Back matter: Everything printed at the end of the book after the main body of text. Includes appendices, bibliographies, glossaries, footnotes, and indexes.
