Examines two traditional approaches to the measurement of library service--the gathering of circulation and reference statistics--and relates them in a statistical model in an attempt to define real standards against which a library's activity can be compared. Graphs comparing reference and circulation statistics are included. (Author/JD)

Describes a computer aid developed to assist in academic library reference service using the DataPhase Circulation System, an automated system that features full cataloging records in database and permits local programing. Access points (subject, type of reference work, course) and database structure and user screens are highlighted. (EJS)

Proposes and investigates feasibility of using three new variables in addition to simple activity counts in measuring reference services: (1) user questioning regardless of where activity occurs; (2) treating individual user and question as unit of analysis; and (3) examination of questioning in context of other library use.
