American Memory This link opens in a new windowProvides information on, and access to, digitized versions of primary-source collections on American history and culture, including photographs, documents, sound recordings, and motion pictures. This site can be a bit tricky to use, as some of the collections linked to are not available online. But many interesting primary source documents can be found through American Memory. For example, try searching for "pork" and browsing everything from early advertising for meat-packing plants to a newspaper editorial about soldiers returning from the Civil War.
