A DL example
• Library of Congress American Memory
project

– “American Memory provides free and open access through
the Internet to written and spoken words, sound recordings,
still and moving images, prints, maps, and sheet music that
document the American experience. It is a digital record of
American history and creativity. These materials, from the
collections of the Library of Congress and other institutions,
chronicle historical events, people, places, and ideas that
continue to shape America, serving the public as a resource
for education and lifelong learning.”

• This is both a review of the planning you have
done and a chance to learn from what others
are doing.
