The Phoenix Public Library is a municipal library system serving Phoenix, Arizona, and operated by the city of Phoenix. There are 16 branches currently in operation citywide, anchored by the flagship Burton Barr Central Library on the northern edge of downtown Phoenix. Four of the 16 locations were designed by prominent local architect Will Bruder: the Burton Barr central library, the Cholla branch location at Metrocenter Mall, the Mesquite branch at Paradise Valley Mall, and the Agave branch in far northwest Phoenix. Many of its branches are named for endemic desert plants.
