With the growing popularity of e-books, questionable profitability in print book development, changes in publicity, and new review methodologies, almost every publisher is considering a variety of strategies for book publishing.
Some publishers are developing e-books first. If the e-book sells well and seems to justify the cost of a print run, then they develop the print version. Others are developing selected books only as e-books. These books are created as either separate titles, elements of other books, or serial publications. Many are using e-books for sales and marketing purposes. This allows publishers to create e-books that can be used for review and publicity before first pages. It also avoids the cost of printed galleys and starts the sales and marketing cycle earlier.
