Aiming to understand how scholars of East Asian Studies use East Asian sources (mainly in Chinese, Japanese, and Korean) in their research, this citation study analyzed bibliographies of 213 PhD dissertations from 32 (East) Asian Studies programs in the United States and Canada from 2013 to 2015. The study examined the number and percentage of East Asian sources cited in each bibliography, as well as format and publication year of each East Asian source cited. The results have important and practical implications for collection development and management.
