The kindle doesn't seem to work with most or all public library software programs. It may be that the Kindle software is too proprietary. Nook and Nookcolor are getting high marks from textbook and magazine companies. Try several and get a pamphlet or go on line to compare features and prices. Also look for reviews on customer service. A plus with the Nooks is having a store and people to help you. If not super techie this is a consideration.
