Cover Page
This month’s cover shows a woman working with Zatocoding, a system of information retrieval that employs special cards with notches representing information in the document to which the card referred. The system was developed by Calvin N. Mooers in 1947. Mooers once commented that Zatocoding “antagonized librarians” because it was an automation of work that had traditionally required human thought to retrieve information. The image is part of the Calvin N. Mooers Papers at the Charles Babbage Institute, an archive dedicated to the history of computing and information technology located at the Elmer L. Anderson Library of the University of Minnesota-Twin Cities. Visit the Babbage Institute online at www.cbi.umn.edu to learn more about Mooers and other historical computing collections.
