The Reunions collection contains materials related to University reunions from the Class of 1871 to the present. Items include publications; ephemera; mailings; photographs; and planning documents such as meeting minutes, itineraries, registration forms, and information about alumni. Materials were generated by the Office of Alumni Relations and by alumni volunteers who worked with them to plan reunions. Among other activities, reunion planners collected updates from alumni and used them to create a booklet about members of a given class. This publication has varied in style and has been circulated under a variety of titles over the years: "Questionnaires," "Personal History," "Autobiographies," "Life Lines," "Alumni Updates," "Bulletin," "Who's Who in the Class of ___?," and more recently "Class Memory Book." In these booklets, alumni have shared memories from the University of Rochester and details about their career paths, families, and other aspects of their lives.
