Based on data gathered during a full 5-day, 40-hour week of visiting time, this study determined various characteristics of visitors to the New York State Library (NYSL) main facility; e.g., traffic rates, user intent, and user status. Visitors exiting the library were counted, short interviews were conducted with 25 percent of the total visitors counted, and traffic flow data were used to determine appropriate weightings for interview results obtained from different time intervals. It was found that NYSL averages 313 different visitors per day, with Tuesday being the busiest of the week. Forty-two percent of visits are made in connection with New York State government activity, and more than half of all visitors are government employees. The report details the study methodology, analyzes the results, and suggest areas for further study. Tables illustrate the findings. (FM)
