The history of browsing in a distributed database, such as the Internet, is presented in a global history window. Each document browsed is represented by a page icon selected as representative of content in the browsed document. Each link between browsed pages is represented by a roadway to connect the respective selected page icons. The user's present position is indicated by an icon or other manner. Features proximate to the user's present position may be enlarged. In the preferred embodiment, the global history map is presented on an apparently curved surface having a variety of features which serve to orient the user in the map. With each new request for retrieval of a new document, the global history map window is presented wherein the building of a new roadway serves as a progress indicator for retrieving the new document. A new page icon indicative of the content of the new document is selected. The new page icon is presented proximate to a terminus of the new roadway. An end of road icon at the terminus of the new roadway is presented once the new document is retrieved.
