San Diego County Library

What San Diego County Library does

San Diego County Library (SDCL) is a public library system operated as a department of the County of San Diego government, serving county residents through 33 physical branch locations, 5 MySDCL kiosks, bookmobiles, and digital services. Founded in 1982, SDCL operates with a staff of 101-250 employees and is headquartered at 5560 Overland Avenue, Suite 110 in San Diego. Library services are provided free of charge to San Diego County residents who obtain a free library card, with the system funded primarily through county taxes and supplemented by California State Library funding and monetary donations (which a Matching Funds program doubles for collection purchases).

SDCL's core technology stack is built on BiblioCommons for catalog search, account management, events, and the patron portal (MySDCL), with OverDrive and the Libby app powering the digital collection of eBooks, eAudiobooks, and eMagazines. The library licenses multiple third-party digital learning and research platforms — Rosetta Stone (30+ languages), Gale Presents: Udemy (4,000+ courses), ABCmouse (early childhood education for ages 2-8), ProQuest eLibrary (research databases for grades 6+), and TeachingBooks (children's/YA literature resources). Link+ interlibrary loan and the Circuit media-sharing network extend catalog reach beyond the county's boundaries.

The go-to-market and business model are community-led and event-driven: SDCL reaches residents through seasonal programming (Summer Learning Challenge June 1-August 31), Pages in the Park community events, year-round storytimes, STEAM programs, citizenship classes (in partnership with Jewish Family Service), and the Library High School online diploma program for adults aged 19+. Unique flagship programs include Discover & Go (free museum passes to 200+ institutions) and the California State Parks Pass Program (free passes to 200+ state park units). The 11-new-libraries-in-11-years capital program — most recently the 16,000 sq ft Zero Net Energy Lakeside Library (2025) and the announced Casa de Oro Library project — reflects a sustained facilities buildout, with Friends of the Library groups operating at each branch to raise supplementary funds and operate bookstores.
