Abstract: Embodiments provide a system for content distribution and protection. The system first receives an order from a user for a protected document. In response to a successful user authentication, the system generates an access code for the user to access the protected document. In response to a received user reading request, the system validates the access code for a reading session. The system then transfers a set of URLs for accessing a set of pages and associated metadata in the protected document to the user. The set of URLs are valid for a period of time. Responsive to a request for reading a next set of pages, the system again validates the access code for the session and transfers another set of URLs for accessing the next set of pages. The system also logs user activities related to the protected document.

Abstract: A notepad application enables users to create notes associated with electronic documents. The document, configured for rendering by an eReader browser application, is associated with a table of contents defining a plurality of sections of the document. The notepad application displays a note window associated with a section of the document within a user interface of the browser application. When a user generates a note in connection with the note window by indicating a location within the document, the notepad application adds the note to a note region in a note object that is associated with a section of the document defined by the table of contents. The notepad application then can access the note using the table of contents of the document.
