Lantern slides were compiledas instructional aids for the public school curriculum. More than 20,000 unique images dating from 1856-1939 document a wide variety of subjects, including New York State, North American and world geography, history, natural sciences, fine arts, trades, industries, education, and schools. Thousands of slides were produced by the Division of Visual Instruction and sets of slides were loaned to schools throughout the State from 1886 to 1939.
