Jefferson - A very interesting application that will allow you to study legislative history from the Library of Congress.
Version: 1.1 Beta 5Jefferson is an Aqua front-end for the THOMAS legislative-history database maintained by the Library of Congress.
Operating System: Mac OS X
Jefferson uses the same HTML queries available to the general public at the THOMAS web site, but instead of displaying the results as a web page, it presents them in a form that is much easier to read and browse.
One of the most helpful features is that you can save Jefferson browser documents on your computer so you can use them offline.
