In 1968, Leedice Kissane published a biocritial study of Ruth Suckow for the Twayne Authors Series. In 1994, she donated her research photocopies to the Ruth Suckow Memorial Society. In 2003, the Ruth Suckow Memorial Society donated these materials to the University of Iowa's Special Collections Department. These are photocopies of essays about Suckow and items written by Suckow. Kissane's own research notes and manuscript are not part of this collection. Most of the contents of Kissane's Research files were integrated with the Ruth Suckow main collection. However, it was thought valuable for researchers interested in how she conducted her research to keep a list of the items in this series. In almost every instance, the item is a photocopy or photographic reproduction.
