QUERYING AND NAVIGATING CHANGES IN WEB REPOSITORIES

A system and method is provided for identifying if a document linked from a base document has changed over time. A first time and a later second time are identified. A link in a base document is recursively identified, where the link refers to a linked document. A version repository is searched to determine if the repository stores versions of the linked document associated with the first and second times. An indication is provided to the user if it is determined that a version associated with the first time and a version associated with the second time are stored in the repository.
