DynamicBooks to allow texbooks to be rewrote by instructors.

In a page borrowed to Wikipedia, Mcmillan, one of the five largest publishers of trade books and textbooks, has announced plans to introduce a software called DynamicBooks that will allow college instructors to edit digital editions of textbooks and customize them for their individual classes, according to the New York Times.
Quoting the paper, "professors will be able to reorganize or delete chapters, upload course syllabuses, notes, videos, pictures and graphs," and most interestingly, "rewrite or delete individual paragraphs, equation or illustrations."
The way the software is set up, instructors will have the power to go online, log on to the authoring tool and make whatever change they want without even the need for prior authorization.
The program is set to start in August when 100 titles will be available for sale through DynamicBooks.
One of the advantage of the DynamicBooks edition is that the titles offered will sell for much less than the the price of other ebooks because of their personalized character.
