User editable textbooks

["B.G. Sloan" <bgsloan2@yahoo.com>]

"Macmillan, one of the five largest publishers of trade books and 
textbooks, is introducing software called DynamicBooks, which 
will allow college instructors to edit digital editions of 
textbooks and customize them for their individual classes. 
Professors will be able to reorganize or delete chapters; upload 
course syllabuses, notes, videos, pictures and graphs; and 
perhaps most notably, rewrite or delete individual paragraphs, 
equations or illustrations."
