Change in Creative Commons License

It's come to my attention that the Creative Commons License that we had posted: Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 United States License did not allow instructors to bundle selected chapters for distribution to students due to the "no derivatives" restriction. This wasn't our intent, in fact this is precisely what we do for instructors at UMass Lowell. To remedy the situation, the following license has been posted on our web site. Applied Discrete Structures by Alan Doerr & Kenneth Levasseur is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 United States License Most of the existing files still list the No Derivatives restriction a this time, but they will be updated as we proceed.
