Book excerpt: Foreword by Tracie D. Hall Community engagement isn’t simply an important component of a successful library—it’s the foundation upon which every service, offering, and initiative rests. Working collaboratively with community members—be they library customers, residents, faculty, students or partner organizations— ensures that the library works, period. This important resource from ALA’s Public Programs Office (PPO) provides targeted guidance on how libraries can effectively engage with the public to address a range of issues for the betterment of their community, whether it is a city, neighborhood, campus, or something else. Featuring contributions by leaders active in library-led community engagement, it’s designed to be equally useful as a teaching text for LIS students and a go-to handbook for current programming, adult services, and outreach library staff. Balancing practical tools with case studies and stories from field, this collection explores such key topics as why libraries belong in the community engagement realm; getting the support of board and staff; how to understand your community; the ethics and challenges of engaging often unreached segments of the community; identifying and building engaged partnerships; collections and community engagement; engaged programming; and outcome measurement.
