摘要：Techniques and systems are disclosed for providing changed content
identification for an online document that is accessed by a user or user agent. A referencepoint for an online document that a user or user agent is interested in accessing is
identified, comprising a stored prior version of the document. The prior version of thedocument is retrieved, when the user or user agent accesses the online document, suchas by using the reference point. Elements of the prior version are compared withelements of a current version of the document, to determine whether there are
differences between the versions. If changes are identified between the prior version andthe current version, the current version is automatically updated with visual or auditoryrepresentations that identify those changes of content.
