Zoomify (http://www.zoomify.com/default.htm) is a piece of imaging technology new to the DMR. It allows users to view, zoom, and pan detailed images in a more quick and efficient way.
The Muncie and Delaware County Historical Maps and Atlases Collection (http://libx.bsu.edu/collection.php?CISOROOT=/HistMaps), and the Sanborn® Fire Insurance Maps of Muncie, Indiana (http://libx.bsu.edu/collection.php?CISOROOT=/SanbrnMps) both feature this technology.
When in a collection, just click the "Zoomify" button to be directed to the easy-zoom interface. Zoomify will soon be added to more DMR collections.
