Rare Book School

David L. Vander Meulen, professor of English at the University of Virginia, shows his class the Hinman Collator machine developed to collate books during a Rare Book School summer camp class held at the University of Virginia in Charlottesville, Va. The Hinman collator uses electrical lights and mirrors to “converge” two texts into one, highlighting variations between the copies. Photo/Andrew Shurtleff
