From 1932 to 1970, McColloch Hall contained West Liberty State College's library and also housed an art department, home economics, and the first student union, The Center. Originally erected as a freestanding building, it was joined with Curtis Hall in 1961 to become the East Wing of Main Hall. Its name honored Milton McColloch, an 1893 graduate of the West Liberty Normal School, a descendant of a famous pioneer family, and a member of the West Virginia House of Delegates from Ohio County.
