archival collection of materials related to the history of the university.

Campus The Ohio Wesleyan campus is next to downtown Delaware, and is bisected by Sandusky Street, the main north–south street through the heart of the city. The street informally divides the campus into an eastern sector composed mainly of academic buildings and a western sector composed mainly of residential and administrative buildings. Many facilities have been constructed in the last two years, with substantial benefit to science, art, and athletic programs on campus. Other facilities and off-campus programs OWU operates several facilities outside campus: The Philadelphia Business Center, Wesleyan in Washington, The New York Arts Program for the performing, visual, and media arts (a GLCA arts program), Perkins Observatory, The Strand Theatre, and the Kraus Wilderness Preserve. Perkins Observatory is situated in Delaware on land separate to the main campus. The observatory is named after Hiram Perkins, a former professor of mathematics and astronomy at the college. When the observatory was built in 1931, it housed the third-largest telescope in the world, which has since been moved to Arizona. The Perkins dome now houses a telescope, which is the second-largest in Ohio. The university also maintains offices for study abroad, US domestic study, and internship programs. Such programs include: Wesleyan in Washington, which allows students to study for a semester in Washington, D.C., in research and internship positions. The Philadelphia Center offers students hundreds of internship and field placement opportunities off-campus and the chance to live independently. and the New York Arts Program, which allows students of the arts to gain a semester of hands on experience in the arts in New York City. Community relations OWU has strong community ties with the City of Delaware. Students participate in Delaware's community through a variety of educational, social, and cultural programs. The student-led Columbus Initiative, founded in 1989, is an experiential learning partnership between OWU and Columbus public schools. More than 150 Ohio Wesleyan students from this program tutor and mentor underprivileged pupils from Columbus. The Ohio Wesleyan Ambassadors Program (ISAP) promotes cultural diversity and ethnic awareness within the local community, and exposes international students to American culture through the
