According to the website, "The development of early American animation is represented by this collection of 21 animated films and 2 fragments, which spans the years 1900 to 1921. The films include clay, puppet, and cut-out animation, as well as pen drawings. They point to a connection between newspaper comic strips and early animated films, as represented by Keeping Up With the Joneses, Krazy Kat, and The Katzenjammer Kids. As well as showing the development of animation, these films also reveal the social attitudes of early twentieth-century America." Among the many subjects listed in its index are automobiles, circuses, magic, husbands/wives, as well as topics related to World War I such as Emperor William II and propaganda. The animations can also be accessed through an alphabetical title list, a chronological title list, and search by keyword. There is also a link to "Notes on the Origins of American Animation, 1900-1921" by Scott Simmon that provides brief introductions to particular works. The films were taken from different collections within the Motion Picture, Broadcasting and Recorded Sound Division of the Library of Congress. The site also provides some suggestions for teachers, aimed primarily at K-12 instructors, that is divided into the categories of History, Critical Thinking, and Arts & Humanities.
