Methods and apparatus of the invention enable users to request access to one or more electronic images of pages in a physical text. When the user is identified and user ownership of the physical text is confirmed, the user is given access to the requested electronic images in accordance with the one or more access rules. Electronic images of pages may be automatically added to a user-personalized library of electronic content for later access. A flag associated with the user and the pages images may be set to indicate confirmed user ownership of the physical text. A user may purchase a physical text itself or purchase an item that the physical text normally accompanies. Electronic page images may be acquired by scanning printed pages of the text or from a user upload. Access to the electronic images of a physical text is based on user ownership of the physical text.
