The Maslach Burnout Inventory (MBI) has been used to measure burnout among Academic Librarians. To investigate burnout prevalence, the authors surveyed a cross-section of Academic Librarians using the Copenhagen Burnout Inventory (CBI), a highly validated instrument that assesses burnout in “helping professions." The CBI measures work-related burnout in terms of physical and psychological exhaustion. A sample response of 1648 Academic Librarians quantitatively proves that: 1) burnout among Academic Librarians exists; and 2) certain gender and age groups are at greater risk. This data will allow future researchers to explore causality and prevention of burnout among Academic Librarians.
