A web browsing system for retrieving a web page whereby the web page comprises associated frames, content data and context data (e.g. navigational buttons, hyperlinks to other web pages etc.). The system is usable with a distributed data processing system comprising a server computer and a client computer, whereby the web page is stored on the server computer and is transmitted over a network to the client computer. The web browsing system comprises a function for providing a bookmark to the web page and also comprises a function to retrieve the bookmark. Once a bookmark has been retrieved, the web page and the structure of the web page, namely, the plurality of frames, the content data and the context data are displayed.

Information retrieval system

A method of retrieving information by navigating within a web browsing session. The information is stored on a server in a hierarchical tree comprising a root node, top-level child nodes representing information categories and leaf nodes representing information sub-categories. Each of the nodes has an associated information unit. Initially, an information unit associated with the root node is displayed in an information space. A user then performs navigation operations from the root node, by selecting a first top-level child node, traversing the leaf nodes and selecting a first leaf node. A first information unit associated with the first leaf node is subsequently displayed in the information space. This first information unit is stored, the navigation operations are repeated on a second top-level child node until a second information unit is displayed in the information space. The user then re-selects the first top-level child node and in response to the re-selection the first information unit is automatically re-displayed in the information space.
