Book packaging (or book producing) is a publishing activity in which a publishing company outsources the myriad tasks involved in putting together a book—writing, researching, editing, illustrating, and even printing—to an outside company called a book-packaging company. Once the book-packaging company has produced the book, they then sell it to the final publishing company.
In this arrangement, the book-packaging company acts as a liaison between a publishing company and the writers, researchers, editors, and printers that design and produce the book. Book packagers thus blend the roles of agent, editor, and publisher.[1] Book-packaging is common in the genre fiction market, particularly for books aimed at preteens and teenagers, and in the illustrated non-fiction co-edition market.
