Abstract
Method and systems are described which can be used to track and manage the states of electronic media in a communications network. The electronic medium can be restored, archived, and used to create new electronic media. Moreover, the electronic medium can be superseded and deleted. Additionally, notification processes can be used to prioritize and emphasize certain portions of the electronic medium. Access to the electronic medium may also be blocked or limited to certain recipients of the medium.
