Many people consider the WWW as the knowledge base or library of mankind, and big search engines claim to be its librarians. Keyword based search, global ranking methods and rather simple personalisation are, however, just poor attempts to manage the WWW's huge amount of information in a reasonable manner, and are still far away from the service provided by librarians. In this talk, after a detailed analysis and discussion of the current situation new, fully decentralised administration approaches on the basis of peer to peer systems will be introduced. They employ locally working background agents using confidential user information as well as the users' work histories and files without transferring them to any other location. In addition, the contemporary search engines' method of working on indexed copies of the WWW will be replaced by a sophisticated search in suitable, locally built structures using new clustering and distance measures apt for entire web documents as well as a user- and access-based ranking mechanism. First research results obtained by employing this method will be presented.
