Between rhizomes and trees: P2P information systems
The aim of the first part of this paper is to provide an overview of information retrieval in Peer–to–Peer (P2P) information systems in the file–sharing domain. Starting with a general overview of the concept of P2P information systems, the paper then focuses on five desktop–accessible P2P information systems: Napster with its clones OpenNap and eDonkey, and Gnutella and FastTrack (i.e., Kazaa). A detailed description is given of the attributes and properties of each P2P file–sharing information system, followed by an evaluation of the respective P2P file–sharing applications, taking each in turn and examining their respective strengths and weaknesses. This paper concludes with a critical comparative analysis and gives some suggestions for further investigation.

Internet time and the reliability of search engines
Search engines are unreliable tools for data collection for research that aims to reconstruct the historical record. This unreliability is not caused by sudden instabilities of search engines. On the contrary, their operational stability in systematically updating the Internet is the cause. We show how both Google and Altavista systematically relocate the time stamp of Web documents in their databases from the more distant past into the present and the very recent past. They also delete documents. We show how this erodes the quality of information. The search engines continuously reconstruct competing presents that also extend to their perspectives on the past. This has major consequences for the use of search engine results in scholarly research, but gives us a view on the various presents and pasts living side by side in the Internet.
