The Clark T. Sawin Memorial Library and Resource Center was established at the Endocrine Society's national office in 2006. During his lifetime, Dr. Sawin was fascinated with the history of endocrine investigation and clinical endocrinology, and spent many years pursuing his passion acquiring a vast history of medicine library. By cataloging and preserving historical endocrine literature and artifacts, the library plays an important role in the Endocrine Society's mission to support the field of endocrinology. Today, the library holds more than 8,100 items including books, oral histories, meeting programs, photographs, personal and research papers, medical instruments, and the Pediatric Endocrine Society Collection.
