Book “packaging” can mean being hired by a publisher to be the all-in-one agent for idea-to-delivery of finished books. The main reason publishing houses do so is for non-standard, labor-intensive books, that is, anything other than a text-only book by a single author. Books that are highly illustrated or elaborately designed or incorporate non-print materials, such as CDs, DVDs, game pieces, or other merchandise, are beyond the ken of most publishers.
