Team Southie Boys were first to arrive at the Library of Congress, followed by Team Geniuses and Team Air Force in third. Teams were advised to seek one of three specific books (titled "Poltroons & Patriots", "Official Histories" and "") each of which covered the final artifact. Team Air Force headed for the card catalogue, followed by Team Southie Boys. Team Air Force was the first to find the artifact, a leather-bound book detailing the history of The Star-Spangled Banner. Within the book were semi-transparent maps with chevrons which, when overlaid, marked the various destinations teams had previously visited. The book included a notation that it had been printed on the Library's old printing press and Air Force went in search of the press. In the press room was a template into which the box, key, medallion and compass fit. With the blank map inserted in the press, the artifacts printed a map to Fort McHenry in Baltimore, Maryland. Team Geniuses apparently stumbled onto the artifact largely by chance and printed the map. Team Southie Boys, having temporarily given up on the card catalogue, searched for a while then returned to the catalogue to locate the final book. They too printed the map.
