Try Will Edgingtons's page, http://www.garlic.com/~wedgingt/mersenne.html . Use used to keep a comprehensive archive of known Mersenne factors. I am not sure how up to date this files are, but it is a good starting point. I still keep the data, but have not had time to update the online copies for a while now for several reasons that have nothing to do with GIMPS or other Mersenne stuffs. For example, the current primary cause of my lack of time is my new project at NASA/Ames: the AI-based planning software that I've been helping to develop for the past few years has been selected, this past Nov., for use by the upcoming Mars 2003 rover missions, to assist the human planners figure out what each rover can likely do during each Martian day. When I have time, I also maintain the mers package of programs - all in C source code and as portable as I know how to make them, which, of course, usually makes them slower than the other available programs - to do various things with Mersenne numbers, including verify that factors are prime, factor any composite factors, try to factor Mersenne numbers with Mersenne primes for exponents, etc., as well as the more "typical" tasks like Lucas-Lehmer tests, trial factoring, ECM, and P-1 of Mersenne numbers themselves. The URL given by Alexander is the primary one, which should have links to all sorts of other things, on my site and several others.
