To celebrate the treasures in its over 110 million item collection, the Library of Congress simultaneously opened an ongoing exhibition and this website on May 1. The site is divided into three parts: memory (history), reason (philosophy), and imagination (fine arts). At present there are 61 treasures, including the items found in President Lincoln's pocket after his assassination, Alexander Graham Bell's notebook entry for March 10, 1876 ("Mr. Watson--Come Here--I want to see you"), and an example of imaginative book design from the Janus Press. The top treasure is a rough draft of the Declaration of Independence. Each treasure is briefly introduced, and the user can then click on a thumbnail image to retrieve a much larger image and more detailed explanation. The online exhibition will provide a "cumulative record of many items that have been on display."
