Bill Young has created a fascinating and well-thought out tribute to the New York World's Fair of 1964-1965, whose theme was "Peace Through Understanding." Easily navigated, the site features a navigation tutorial, which may be helpful, as there is a substantial amount of material contained here. Visitors to the site can search for different information about the Fair by clicking one of the maps of the fairgrounds, or by going to an alphabetical list of the pavilions at the Fair. Within the People, Places, Things section of the site, visitors can read the reminisces of Greg Dawson, the public relations director for the fair and about Mr. Young's own encounter with the legendary Robert Moses, who was the director of the World's Fair. The Stories section features essays and commentaries by visitors to the Web site on the Fair. From the main site, visitors can also send virtual postcards of the Fair, along with shopping for a number of items related to the Fair's history and development. For anyone with an interest in the history of World's Fairs, or American cultural history more generally, this site is quite essential.
