The site is still in beta, but the U.S. government archive has posted an extensive, annotated and searchable archive of the writings of the "top-tier" Founding Fathers: George Washington, Benjamin Franklin, Thomas Jefferson, the Adams family, James Madison and Alexander Hamilton. The site claims to have nearly 120,000 documents in its database. An amazing research source to be sure! Check it out here: Founders Online.
Now how am I going to get any work done!
