The journal is published quarterly,[1] divided into three sections: essays, reviews, and bibliographical notices, announcements and obituaries. Its themes range from philology over historical and religious studies to archaeology and art history. In addition, since 1898 the journal was complemented by the Byzantinisches Archiv series, which was completely split off from the journal in 1994, as well as the infrequent Supplementum bibliographicum, independently published by Robert Browning.
