Sawin Library

History of the Library

Through a generous donation by Dr. Clark T. Sawin’s widow, Mrs. Leslie Sawin, and the efforts of the Sawin Library Committee, co-chaired by Drs. Len Wartofsky and Elliot J. Rayfield, 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. In addition to supporting the endowment of the library, Mrs. Sawin donated Dr. Sawin’s personal library collection which includes more than 6,500 books, meeting programs from endocrine organizations circa 1930 through current day, professional and personal research papers, slides, and many historical articles.

By cataloging and preserving historical endocrine literature and artifacts, the library plays an important role in the Society's mission to support the field of endocrinology. Today, the library holds more than 8,100 items including books, audio and video tapes, medical instruments, and awards donated by members and friends of the Endocrine Society.

The Online Library Catalogue

More than 8,100 books and reference materials are available for circulation free of charge to members through the Society’s online catalog and checkout system. Upon request, books will be mailed to members for use up to two weeks at a time.

Delbert A Fisher Research Scholar Award

The Delbert A. Fisher Research Scholar Award supports an annual fellowship to provide scientists the opportunity to continue Dr. Sawin’s documentation of endocrine history. A fellowship is awarded to one recipient annually for scholarly work on the history of endocrinology, and for the preparation of the Clark T. Sawin Memorial History of Endocrinology Lecture presentation that is featured at the Endocrine Society’s annual meeting.

Partnership with the Pediatric Endocrine Society

In 2012, a special section of the Sawin Library was dedicated to the Pediatric Endocrine Society (PES) to support the history of the field of pediatric endocrinology.This dedicated section of the Library will provide a central place to catalog the important works of pediatric endocrinology. All items donated by the PES and its members are available through the online catalog. Learn more about the Pediatric Endocrine Society History.
