Hi, I do not know which is the best place to ask and the topic is a bit sensible but maybe one of you know more. Frustrated by the lack of libraries to quickly deliver some academic articles from the 1970s that have only been published in digitized form on CD-ROM and DVD I thought about the use of peer2peer networks for academic and E-Learning material. Of course this is often against copyright law but I know that scholars just share non-open-access articles with their colleauges. However to what degree? For instance is P2P more used in countries that have less library budgets and less strict copyright law enforcement? I would not wonder if you can get most copyrighted academic material in P2P networks but it is not easy to get a realistic view - many trackers are accessible on invitation only and they come and go quickly. Here are some I found on a quick search: http://Bitme.org seems to be the largest one http://ScienceHD.info - mostly documentaries http://docspedia.org/ - (aka Docs.Torrent.Ro), ebooks? http://learnbits.me/ - e-learning ? .. More can be found for instance at http://www.torrentking.org/?cat=Elearn and http://filenetworks.blogspot.com/search/label/Torrent%20Sites%20-%20E-Learning%20Trackers Do you know of any studies that give insight to the coverage and impact of such P2P networks to the access to academic material? Or any articles about the relations between institutional libraries and P2P-based digital libraries?
