In the library catalog, there is no single subject term that will find everything on World's Fairs. The subject term Exhibitions applies to all World's Fair materials, but also applies to other kinds of exhibitions.
Good results can be obtained by a keyword search using World's Fairs or Expos, but this will not help you find material on a specific World's Fair or Expo.
For best results, do a subject search using the authorized name of a specific fair from the list below.
