The Glendale Public Library (Library, Arts & Culture Department) is located in Glendale, California, and serves a diverse community of over 200,000 people. The present Central Library building opened on March 13, 1973, on the former site of Glendale Union High School and Glendale College. With 92,600 square feet (8,600 m2) it had over four times the floor space of the old structure. The next twenty years saw major changes in the City of Glendale and in library technology. The latest remodel has brought library users a larger Children's Room and a separate Audio Visual area. The new upper level includes an expansion of the Special Collections room to accommodate the valuable historical information housed there. The redesign of the Reference and Circulation areas has been specifically oriented toward better customer service. The creation of a Business Collection area and a Job Center recognizes Glendale's position as the third largest business center in California.
