The more than 4,000 "chats" received by the University of Central Florida's (UCF) Ask-A-Librarian digital reference service are the subject of this practitioner-based, descriptive case study. Question content from chats received during four semesters between January 2005 and May 2006 are categorized and plotted, by semester, to show the number of questions received in each question category. The study seeks to provide a baseline of descriptive statistics for the UCF digital reference service and to address gaps in the literature about the manner in which patrons are using digital reference services. Further, awareness of question topics can contribute to effective decisions about training and staffing requirements and marketing of services. (Contains 1 table and 6 figures.)
