From the press release:
DynamicBooks, a new subsidiary of Macmillan, unveiled today a new digital publishing platform that allows instructors to freely customize and modify some of today’s most respected textbooks. Using the DynamicBooks’ editing tools, instructors can tailor world-class content to suit their classroom needs by editing existing content or adding new text or media assets. Once instructors “publish” their custom book, their students can choose to purchase either a fully featured digital text or a printed version of the new book.DynamicBooks was created in close partnership with Ingram Content Group Inc. and utilizes Ingram’s successful VitalSource Bookshelf platform and Lightning Source print-on-demand capability.
DynamicBooks seeks to lower costs to students and is working with its publisher partners to do so. As an example, Bedford, Freeman and Worth books will be available in digital form for 40-50 percent of the price of traditional books.
