This article features the Pierce County Library System (PCLS) in Tacoma, where new services are changing the way customers experience the library. PCLS is comprised of 17 branches, two bookmobiles, one Explorer Kid's bookmobile, serves 509,000 people, and has 234,000 cardholders. The evolution of customer expectations and needs motivated the decision to implement self-service checkout stations in some of the branches. An essential component of the redesign is the service triangle. The model is based on three key elements: (1) easy traffic flow; (2) logical movement between holds pick-up, ExpressCheck, and card services; and (3) direct visual lines into the holds area from the staff locations. The author describes how the library prepared for the installation of the service triangle, and how the new service model is being implemented into the library's five branches.
