Can I use my NOOK or iPhone to read digital textbooks?
No, you cannot use your NOOK or mobile devices to read your digital textbooks. Textbooks are complex and usually graphic-intensive they do not display well on small screens. However, if you have purchased eBooks (e.g. Moby Dick, Pride & Prejudice, etc.) that are predominantly text, those are supported on NOOK and mobile devices, in addition to NOOKstudy.
