On December 28, plans were made to construct a new library building (now Brooks Hall), for $227,500. While the library acquired its 10,000th volume in 1924, a fire destroyed the library catalogue the same year. As a result, the library classification system changed to the Library of Congress Classification, which remains in use through the present day. Inter-library loans were introduced in 1925. The new D. H. Hill Library opened with a limited schedule on October 15, 1925, opened with full service hours on January 1, 1926, and was dedicated on June 7, 1926. Built at a final cost of $266,500, including $25,000 for equipment, it was designed by New York architect Hobart Upjohn in a post-colonial style reminiscent of Monticello. The main reading room occupied the whole of the rear of the entrance hall; it and a separate periodicals room provided space for 250 readers, or about 20 percent of the college's total student population. The second floor was occupied by graduate student and faculty seminar and research rooms, while bookstacks with a maximum capacity for 150,000 volumes were housed in the basement. By this time, the main library collection totaled 15,000 volumes, which subsequently rose to about 18,000 following the integration of the various departmental libraries with the main collection. However, only 7,301 of the volumes in the collection were allowed to circulate, with the remaining 11,569 reserved for library use.
