In a 1992 issue of this journal, 12 scholars proposed an ambitious research agenda for the study of the American county. By all accounts, this agenda was both a catalyst and a guide for those interested in the nature, role, functions, operations, and practical relevance of county governments to either continue their research or to launch new studies in this underresearched area. The present article provides a detailed inventory of the research that has been conducted in the eight areas identified in the 1992 agenda. Specifically, which research questions have or have not been addressed satisfactorily? Such an exercise is a logical prerequisite for charting a path for future research on counties; it represents a synthesis of scholarly needs for theory building, hypothesis testing, and cumulative research and the dynamic and enduring knowledge-base needs of county practitioners and elected officials.
