The Mission Hills-Hillcrest/Harley & Bessie Knox Library is located at 215West Washington Street, between Front and Albatross Streets. This library was opened on Jan. 26, 2019 and serves the communities Bankers Hill, Hillcrest, Middletown, Mission Hills and Old Town. Named in honor of the late philanthropists Harley and Bessie Knox, the new Mission Hills-Hillcrest/Knox Library expects to have 350,000 patron visits each year.

The 15,000-square-foot library is more than triple the size of the communitys previous library that was built in 1961. It features modern amenities, including designated areas for teens and young children, a community meeting space, study rooms, computer labs, drought-tolerant landscaping, an underground parking garage and a design expected to achieve LEED Gold certification.
