Couch Biology Library, CB#3280-Coker Hall, University of North CarolinaOn the occasion of the centennial ofThe Ohio Journal of Science, this paper provides a short history of its development. From an inaugural issue of 16 pages in November 1900, The Journal has matured into an important serial featuring peer-reviewed articles in science, engineering, technology, and education, or their applications; book reviews; four special issues devoted to a theme; Academy presidential addresses; and obituaries of deceased members. Guided over the years by a sequence of 18 editors, The Journal has undergone title changes as its disciplinary scope broadened: The O.S.U. Naturalist (Nov-Dec 1900), The Ohio Naturalist (Jan 1901-Jun 1914), The Ohio Naturalist and Journal of Science (Nov 1914-Jun 1915), and The Ohio Journal of Science (Nov 1915-present). In the past century The Journal has developed from an Ohio natural history serial to an interdisciplinary science journal of international use and respect. Copies are sent to 1900 individuals and organizations, including 37 foreign countries
