On November 18, 1896, Old Main was completed and the library was place on the third floor.  May Shelley was the first library director.  In 1918,  the library was a depository for books and magazines to be sent to the service men in training camps and to the troops in the first world war. In 1928, the library was moved to the newly constructed  Light Hall.  It moved in 1936 to the newly remodeled quarters in Fleming Hall. In 1946, Edward Werner became Library Director and introduced the Southwest Collection and the beginning of the Audio-Visual department.

In 1955 it was decided that Old Main be condemned and fifteen feet of the hill cut away to make room for the new library. The college maintenance department completed the demolition, as there were no bids received. Faculty petitioned to rename the college library for J. Cloyd Miller,  the current college president. The library received a major addition in 1971. Automated cataloging and interlibrary loans came to Miller Library in 1972,  but it was not until 1983 when Jim Essick,  the Library Director at that time,  received a grant for $180,000 to automate the library for circulation and the purchase of computer terminals. Miller Library became a member of the Federal Depository Library Program, stewards series of government publications beginning in January 1974.   Miller Library expanded in 1997 to house the Library and Outreach Services and Technology (media services). The Teachers Learning Center materials came into the library from WNMU’s School of Education in 2012.  In 2018,  the renovation for the new student computer lab was completed with an additional six study rooms. In 2019,  the rest of the library received new carpeting and the specialty collections on the main floor were reorganized and re-positioned for better accessibility.
