The Cooper-Hewitt Library has a large collection of over 2,000 World’s fair catalogues and books. Many are the official guidebooks that visitors could purchase with descriptions of pavilions and that helped locate sights and other points of interest. As a teenager, my mother had loved the 1939 World’s fair, so that when it came to New York City again in 1964-65, she wanted to see another World’s fair and have us children experience the same excitement and wonder.
