The Cholla Branch Library is a publicly funded and managed library that serves more than 1.6 million residents in the city of Phoenix in Maricopa, Arizona. It is an affiliate branch of the Phoenix Public Library, which was founded in 1897 and started as a women's Friday Club with 14 women who organized to start a public library. In 1977, in response to the growing need for library services, the Cholla Branch was opened. This 30,000-square-foot, two-level building contributes to the overall collection and services of the county library system, which includes more than nearly 1.5 million books and serial volumes, more than 127,000 e-books, more than 195,000 audio files, and more than 2777,000 video files. Additionally, the library system hosts over 4.7 million visitors a year at its 12 sites, circulates over 10 million items, and has over 800,000 registered borrowers.
