Abstract: A tool is disclosed that assists a user to assimilate, interrelate, and remember a succession of resources that are retrieved by a computer under the direction of the user. In particular, some embodiments of the present invention are ideal for assisting users in browsing the World Wide Web, but are equally well-suited to users who retrieve a variety of tangible and intangible resources (e.g., laboratories samples, inventory, database entries, etc.) with the assistance of a computer. To this end, the illustrative embodiment of the present invention monitors a succession of resources retrieved by a computer under the direction of a user, records the address of each resource and displays a graph of nodes and edges representing the resources and an indication of the order in which they were retrieved.
