In a search session through a browser for pages on the World Wide Web (Web), a system for precluding repetitive accessing of documents linked to hyperlinks in a plurality of hypertext documents. The system is directed to a Web communication network with user access via a plurality of data processor controlled interactive receiving display stations for displaying received hypertext documents of at least one display page containing text, images and a plurality of embedded hyperlinks, each hyperlink being user selectable to access and display a respective linked hypertext document. In addition to precluding hyperlinks which had been activated in previous pages and/or hyperlinks which have been discounted merely by having been present in previous pages, the Web browser may be setup to permit the user to specifically discount individual hyperlinks or groups of hyperlinks. Also, the Web browser may be setup to preclude repetitive hyperlinks in subsequent Web pages from searches from different search engines.The basic system comprises search means for locating and providing to receiving display stations hypertext documents, combined with a Web browsing system operatively associated with the receiving display station including means for querying said search means for hypertext documents, means for activating hyperlinks to linked documents and means responsive to said activating means for accessing the linked documents. The browser also has user interactive means for discounting hyperlinks in received Web documents, and means precluding the accessing of any document linked to previously discounted hyperlinks.
