Scottsdale Public Library, Public library in Scottsdale, Arizona.

Mustang Library is the first and largest branch of the Scottsdale Public Library, opened on June 13, 1987, when it was the largest branch library in Arizona. The tan stucco building has a flat roofline, a pale yellow upper wall with a grid of dark rectangular windows, and a recessed entrance under a sign reading "MUSTANG LIBRARY". Low concrete steps flanked by low walls and small spiky plants lead to the doors.

The library was founded in 1955 and grew from a small collection into a major educational resource for the community. Over the decades, it expanded its services to meet the changing needs of Scottsdale's growing population.

The library operates a Culture Pass program that gives cardholders free entry to museums and cultural institutions across Maricopa County. This makes arts and culture available to residents without cost barriers.

The library is centrally located and accessible by foot or car, with parking available on-site. Visitors should note that hours vary on weekends and a valid ID is required to access member services and borrow materials.

The library operates a seed library where visitors can pick up free seeds and learn desert gardening techniques suited to Arizona's climate. This program helps locals grow plants that thrive in the region's hot and dry conditions.
