The American Society of Church History (ASCH) was founded in 1888 with the disciplines of Christian denominational and ecclesiastical history as its focus. Today the society's interests include the broad range of the critical scholarly perspectives, as applied to the history of Christianity and its relationship to surrounding cultures in all periods, locations, and contexts. The society was founded by Philip Schaff. The ASCH records are housed at the Presbyterian Historical Society in Philadelphia, Pennsylvania. On behalf of the ASCH, Cambridge University Press publishes the quarterly academic journal Church History: Studies in Christianity and Culture, which was established in 1932. The journal is regarded as highly authoritative in its field, and is compared to the British Journal of Ecclesiastical History.
