(This Site Will be Backed Up at The University of Georgia Shortly)
This site was originally established at the Graduate School of Industrial Administration,
Carnegie-Mellon University in August of 1995. The orginal web-server was a 100 mhz
machine running WINDOWS NT 3.51. The original link was:
http://voteview.gsia.cmu.edu
In 2000 the web-server was moved to the Department of Political Science at the University
of Houston with the link:
http://voteview.uh.edu
This website is now affiliated with the Department of Political Science at the University
of Georgia. It is maintained off campus solely for stability purposes.
The primary purpose of this website is to make available the data that Howard Rosenthal and Keith Poole generated out
of their many research projects. Keith and Howard adhere to the policy that all
of their datasets and software are made freely available to anyone who asks for them. This webserver
was established for this purpose. If you cannot find what you need on the various pages send Keith
an E-Mail at: ktpoole@uga.edu
