City directories are among the most comprehensive sources of historical and personal information available. Their emphasis on ordinary people and the common-place event make them important in the study of American history and culture. One of the few means available for researchers to uncover information on specific individuals, these directories provides such information as: Addresses; City and county officers; Heads of families, firms and names of those doing business in the city; Lists of city residents; Occupations; and Street Directories. In addition, researchers can learn much about day-to-day life through analysis of information on churches, public and private schools, benevolent, literary and other associations, and banks. Finally, most directories include advertising, often illustrating the products being sold. This information lends valuable insight into the city���s lifestyles and illustrates popular trends.
