Chicago Public Library organizational chart

Chris Brown, Commissioner

Chicago Public Library Commissioner Chris Brown has spent his career creating opportunities for transformative learning through public libraries. Brown, who joined CPL in February 2021, leads one of the largest library systems in the world, with a budget of $130 million and 81 locations, including three regional hubs and a 750,000-square-foot central library.

Prior to CPL, Brown most recently served as Deputy County Librarian at Santa Clara County Library District. Over his career in libraries, he has led the expansion of Sunday hours in the most under-resourced cities in Santa Clara County, Calif., collaborated with neighborhood leaders on strategic planning initiatives, led the development of the nation’s first online museum pass program and spearheaded market segmentation studies to better understand community needs. Brown is nationally recognized for innovation in libraries, including supporting veterans, parents of court-involved youth and other non-traditional library users.

He was named a Library Journal Mover & Shaker in 2016, an honor recognizing individuals who represent “the outsize impacts that librarians can have.” Brown’s leadership has garnered additional awards, including the Urban Libraries Council Top Innovator Award, the California Library Association PRExcellence Award and a John Cotton Dana Award from the American Library Association. Most recently, he served on the California Library Association board.

Brown earned a master’s in public administration from the University of San Francisco and a master’s in library and information science from San José State University.
