This paper reports on the level of burnout among 504 female (96%) librarians in Moscow and its relations with personal resources. The Burnout Assessment Tool (BAT) was used to measure burnout, and furthermore optimism, hardiness and self-efficacy were included as personal resources. Confirmatory factor analysis (with first and second order factors) confirmed the expected four-dimensional structure of the BAT. Moreover, it was shown that levels of burnout were quite low, and that personal resources were strongly and negatively related with burnout. Although the effect of personal resources varied across libraries it was the same amongst rural and urban library workers. In addition to personal resources, age was a significant predictor of the level of burnout, while tenure turned out to be insignificant.
