Established in 1977 by the National Science Foundation, the American National Election Studies (ANES) remains as vital a national research resource as ever. Their website provides important information about public opinion in the United States along with sophisticated election databases that will be useful to policy makers and social scientists. Along the left-hand side of their site visitors will find the "Reference Library" area, along with the "Data Center", and the equally important "Help Center". A good place to start looking around here is the "Guide to Public Opinion" area. Here visitors are afforded immediate access to tables and graphs that display the "ebb and flow of public opinion, electoral behavior, and choice in American politics over time." The tables and graphs contain data from 1948 through 2004, and they cover everything from partisanship to political involvement. Further along, the "Reference Library" area contains both pilot study and technical reports that may be of greater interest to academics. Additionally, there is a section where visitors can sign up to receive email updates.
