The Ellisor type collection pages were designed and produced as part of an undergraduate project. In 2000 we began to examine and to stabilize within the type collection. The project included the collection of Kniker and record images were acquired. These specimens will be imaged again as part of the current (2007-2010) NSF funded project to improve the entire type collection.
