As an index of biblical references found in both Western and Eastern Christian literature, at present covering the first four centuries but with the intention of extending over the whole of Late Antiquity and the early Middle Ages, BIBLINDEX aims to provide a common tool at the junction of two research areas: biblical textual scholarship and patristic and linguistic studies, investigating the understanding and use of the Bible in the writings of ancient authors. Two particularly innovative features of BIBLINDEX are its spatiotemporal breadth and its multilingual corpus. Access to the data is completely free.
