AUTHOR INFORMATION

STEPHEN L. WILLIAMS is collections manager at the Natural Science Research Laboratory of the Museum of Texas Tech University and adjunct professor in the graduate Museum Science Program, Texas Tech University. He has a B.S. and an M.S. in zoology and an M.A. in museum sciences. Between 1976 and 1990, Williams was collection manager at the Carnegie Museum of Natural History. During this time he participated in the development of the Society for the Preservation of Natural History Collections, the Bay Foundation pilot training program in Los Angeles, and IMS conservation projects and activities. In 1990, Williams moved to Texas Tech University, where he manages the vertebrate research collections, publishes on collection management and care, and teaches preventive conservation.
