Abstract: Libraries face unprecedented challenges today, from budget cuts and book bans to community mental health crises. In this landscape, publishers have a unique ethical responsibility and opportunity to strengthen libraries and cultivate a vibrant community of engaged readers. This presentation will explore how publishers can make a lasting impact through advocacy efforts that combat book bans and secure necessary funding; sponsored programs, author events, and initiatives that create lifelong readers; and underwriting comfortable reading spaces, learning labs, and technology access for all community members. This research will delve into a survey of California libraries and highlight successful sponsored efforts, providing a roadmap for publishers to identify and address the most pressing needs.
