The Web is an open, evolutionary and heterogeneous information space. To exploit this heterogeneous space and better orientate the reader, we developed the HyWebMap system which allows orientation in the space visited by using a benchmark tool, a browser, a history tool and a global image display based on an interactive map. The reader can create a personal space starting from the spaces visited and enrich it by adding and renaming links. HyWebMap allows the reader to add nodes and annotations to personalise his space. HyWebMap notifies and assists the reader when a change occurs in his personal space.
