The American Presidency Project
If you are researching presidential history, or if the current presidential race has simply piqued your interest in the topic, The American Presidency Project is a web site you will want to check out.
Developed by a presidential scholar at the University of California and widely used by scholars and others interested in the presidency and American political history, this resource provides an archive of more than 78,000 documents relating to the American presidency. It includes documents such as executive orders, proclamations, annual State of the Union messages, inaugural addresses, press conferences, Saturday radio addresses, presidential nomination acceptance speeches, presidential candidates debates, and national political party platforms. It also provides audio and video clips; election results; links to presidential archives and libraries; and statistical data on topics such as presidential popularity, public appearances, relations with Congress, and growth of the Executive branch.
This site is also the only online resource that has consolidated, coded, and organized into a single searchable database The Messages and Papers of the Presidents (1789-1913) and The Public Papers of the Presidents/Weekly Compilation of Presidential Documents (1929-2008). You can either search for documents or browse the archives by document category, president’s name, or date.
