This site is one of a kind! Currently, American Memory contains over a hundred collections of historical documents, photographs, maps, film, and sound recordings. You may search the collections in a variety of ways (and it takes some time to become proficient at searching). Again, the pay-off is well worth the effort. http://lcweb2.loc.gov/ammem/phcoll.new.html

The Learning Page is designed to help teachers and students use the collections cited above. You will find all kinds of resources on the Learning Page, including teacher-created and -tested lesson plans, all of which draw on the American Memory collections. http://lcweb2.loc.gov/ammem/ndlpedu/index.html

This is an outstanding electronic resource. It contains hundreds of electronic books and articles, emphasizing at this time the 19th century United States. http://moa.umdl.umich.edu/
