Carol Highsmith talked about and showed her photography, including some from her current project to photograph each state in the country, as well as her earlier project to photograph the entire Jefferson Building of the Library of Congress in detail.   Carol Highsmith discovered the work of Francis Benjamin Johnston while she was photographing Washington, D.C.'s historic Willard Hotel as it was being renovated. Mr. Johnston photographed the formerly lavish hotel in 1901, and his work was used by contractors in the restoration process. In researching her project, she found that Mr. Johnston had photographed several presidential administrations, treaty signings, and significant events. She later decided to follow the path of her predecessor and give all of her photos to the Library of Congress copyright free.
