Diversity has been identified as a priority in library and information services for some time. The limited published research on diversity programs in libraries, though, has focused on academic libraries. This article represents the results of a study of leadership diversity in large, urban public libraries. In the study of members of the Urban Libraries Council, data were gathered with regard to programs related to diversity awareness, staffing, collections, and information services. The research results indicate that diversity-related activities and programs have been implemented in a high percentage of the libraries. However, the level of focus on areas such as retention has not been as consistent, as is the case with the provision of library services and collection development, for example. The research results also indicate the relationship between organizational leadership and administrative structure and activities related to operationalizing diversity in public libraries.
