The National Archives – America’s historical documents
Recently, Richard Byrne over at FreeTech4Teachers.com shared a Civil War resource (General Lee’s map of Gettysburg) from the historical documents section of the U.S. National Archives website. In addition to the Civil War, the site has additional documents around the Constitution, Emancipation, the Louisiana Purchase, and even the Apollo 11 flight plan. These documents can be viewed online as well as downloaded to your computer, often in hi-resolution format.
In addition to historical documents the site has sections devoted to ancestry research, World War II photography, and the recently released 1940 Census. There is also a section devoted specifically to teachers that contains lesson plans along with materials for school tours, getting started with primary resources research, and where to find related resources from their network of state and regional locations.
