Little is known about the organization, characteristics or services offered by academic interdisciplinary gerontology centers located in higher education institutions. This article presents a description and an emerging typology of academic interdisciplinary gerontology centers based on information collected from the Websites of 47 centers. The emerging typology comprised three dimensions: focus, functions and specialty areas. Significant relationships were found between the center's function and focus as well as function and number of specialties. The newly developed typology is useful for classifying and learning about academic interdisciplinary gerontology centers. Students who have an interest in gerontology might use the classification system to select a school that matches their academic goals. Educators and educational administrators might apply the typology's dimensions in program development. The typology might also serve as a useful framework for future research and policymakers could use the information from the typology and center's Websites to support proposed policies. Furthermore, older adult consumers, their families and professional caregivers can use the information to learn about services and resources. (Contains 4 tables.)
