A browser session navigation tool allows a user to browse previously viewed resource pages during a browser session. Each visit to a resource page results in creation of a visit data structure that references (directly or indirectly) the resource page content. The previously viewed resource pages are graphically represented by navigationally related visit nodes displayed in one or more trails or trees, which graphically illustrate the navigation from resource page to resource page. Resource page content may be displayed in the visit nodes, such as a thumbnail image of the resource page. In contrast to typical browser history lists, navigation branches are not truncated. Instead, all previously viewed resource pages are recorded in archive data storage and are displayed in linear trails and branching tree structures of visit nodes. Archived resource page content may be indexed and annotated to be searchable by text, color, and other visual aspects, thereby allowing a user to search the rich record of their browsing experience during the browsing session.
