Barnes & Noble has developed NOOKstudy, a free (as in beer) software suite that could make the average college student’s life a little easier. The software, which will be available for the PC and Mac, gives students the ability to download and organize electronic textbooks, as well as keep all of their notes, syllabuses, and so on in one safe place. Handy. And no, you don’t need a nook to use NOOKstudy.
