Over the course of the Act's 123-year history, over two million individual homestead claims were made. Each and every one of these claims generated a written record known as a case file that was kept by the U.S. General Land Office. Today, these case files exist only as paper originals and are stored in the National Archives in Washington, D.C. The complete collection of case files created under the Homestead Act contains over 30 million individual pieces of paper. These invaluable documents are subject to natural deterioration, fire and water damage. Since 1999, Homestead National Monument of America has been involved in a project that aims to eventually digitize all 30 million documents of the homestead case files collection.
