With colleges about to open for the fall semester, Barnes & Noble officially launched their online textbook rental business, competing with Chegg and others in this fast-growing sector. At the same time, they have added a free “study platform and software solution that gives college students the freedom and flexibility to access eTextbooks, other digital content and organizational tools to learn more efficiently, collaboratively and across content sources and formats.” It works on standard PCs and Mac computers. Called Nook Study, information about the app and downloads are available from http://www.barnesandnoble.com/nookstudy/.Release
