Named for philanthropists Harley and Bessie Knox, the 15,000-square-foot Mission Hills-Hillcrest/Knox Branch Library opened January 26, 2019, on West Washington Street — more than triple the footprint of the 3,850-square-foot 1961 predecessor it replaced — and was designed to achieve LEED Gold certification while serving an expected 350,000 annual patron visits. The branch's programming schedule runs youth sewing workshops, book clubs, teen activities, and preschool storytimes — a community-skills curriculum that extends into hands-on instruction materials available at San Diego Sewing in Hillcrest for participants continuing their craft beyond the library session. A Friends of the San Diego Public Library chapter operates ongoing used book sales at the branch, converting donated inventory into supplemental program funding alongside the City of San Diego's budget for the 37-branch system. The branch maintains a dedicated LGBTQ Books collection, Makerspace, private study rooms, and a computer lab with 24 workstations — community infrastructure drawing the same Mission Hills and Hillcrest self-improvement population as Brainstorm Fitness, where the neighborhood's residents invest in physical development alongside the branch's intellectual and creative resources. The Makerspace extends the Knox Library's service range into hands-on creative fabrication — equipment and workspace beyond what digital lending, computer labs, or study rooms alone can provide — making the branch the most comprehensively equipped public facility in the Mission Hills, Hillcrest, and Bankers Hill service corridor.
