The Gerritsen collection

The Gerritsen Collection was begun by Carl and Aletta Jacobs Gerritsen in the late 1800s. The original printed materials are located at the Kenneth Spencer Research Library of the University of Kansas, with some additional materials located at the Walter Clinton Jackson Library of the University of North Carolina at Greensboro. The online resource delivers two million page images exactly as they appeared in the original printed works. It includes monographs, periodicals and pamphlets in fifteen languages, and is searchable by keyword and Boolean operators.
