What makes a library safe? This question is at the forefront of every librarian’s mind. Too often, safety is addressed primarily through technology—security gates, cameras, and sensors. While these tools can be effective, they are not enough on their own. A truly safe library begins with intentional, well-designed spaces that naturally support visibility, accessibility, and positive use—helping to prevent crime before it occurs. This session explores how thoughtful architectural and interior design, guided by Crime Prevention Through Environmental Design (CPTED) principles, can enhance safety while preserving the welcoming, civic spirit of libraries. Through real-world examples, practical strategies, and case studies, participants will learn how good design can quietly protect both people and collections—without relying solely on surveillance or barriers.
