ALA organizes "Library-21" a futuristic exhibit, at the Seattle World's Fair.
"The Library 21 exhibit, designed primarily to envision the role of technology in libraries of the future, featured a state-of the-art Sperry-Rand UNIVAC Solid State 90 computer programmed to print out a portion of electronically stored text entered from a printed reference book. A photo of the computer at the Library 21 exhibit is available at The University of Washington Library.The exhibit also featured more traditional library services like “Children's World,” which housed 2,000 books from all over the world, and the “Ready Reference Center,” with more than 700 reference titles and a Xerox 914 copier. The UNIVAC computer, however, was the star of the exhibition." Read more and see images from At Your Library
