I have some textbooks and I would like to share them with a friend. The problem is that when I try to click on the book it is opened with the windows 8 reader app and I can't get it to open in ecalibre. Furthermore, my objective was to see if it was possible to add annotations into the text. Both myself and my friend was to add annotations into the physics textbooks as one may do with a physical textbook. If anyone could tackle these to problems I would appreciate it.
