The pages available in one hyperlink traversal from the query results list are not normally visible to us until we choose to explore them but these are the pages that potentially contain the information we desire. Any concept in this taxonomy that attracts the user's attention can be used by the Guide to make Netscape jump to the page or pages that contain that concept. The Browse Guide is a convenient way to organize information for a specific topic of interest to either a person or a group project. The Guide can be saved for later reference or augmentation by additional Web searching. Or a person interested in cryptography might obtain a copy of a cryptography guide collected and edited by an expert.
Guides are thus a form of structured bookmarks for organizing reference information.
One could imagine augmenting a Web site with a conceptual index of that site, allowing visitors a different way to find information embedded within the site's web. It has the feeling of an assistant who is keeping a constant index of your travel through the Web. When the browser requests a document, the proxy fetches it from the network and forwards it to the browser. The proxy also scans the document for hyperlinks and adds each link to a queue of documents to be fetched. In a separate parallel thread, the proxy fetches documents cited on the queue and forwards the contents to the Indexer.
