Hundreds of libraries and archives exist online, from university-supported sites to individual efforts. Each one has something to offer to researchers, students, and teachers. This list contains over 250 libraries and archives that focus mainly on localized, regional, and U.S. history, but it also includes larger collections, eText and eBook repositories, and a short list of directories to help you continue your research efforts.Three examples:
Missouri Historical Newspaper Project (scanned and searchable issues from 13 newspapers across Missouri. Some 19th century, some early 20th century.)

American Journeys "This site contains more than 18,000 pages of eyewitness accounts of North American exploration, from the sagas of Vikings in Canada in AD1000 to the diaries of mountain men in the Rockies 800 years later."
