Glendale continued to grow, particularly to the north, and it was clear another library was necessary. Land was purchased from nearby Midwestern University, with the proviso that the city would only use the land for a library. In July 1998, the groundbreaking ceremony for the Foothills Library was held. The 33,500 sq. ft. branch library was opened on July 22, 1999.
Foothills Library was the first library in Arizona to offer the convenience of a drive up window square foot facility.
