The Eichstätter Konkordanzprogramm zur griechischen und lateinischen Epigraphik (ConcEyst) provides a representative text corpus of both Greek inscriptions, especially from Asia Minor, and Latin inscriptions in concordance format. Originally emerging from a DFG project on inscriptions from the Roman province of Pontus-Bithynia, ConcEyst today offers one of the most comprehensive epigraphic databases of Greek and Latin inscriptions. Unlike comparable projects, ConcEyst provides a clear output of search results in concordance format and access to a retrograde index. It is thus an indispensable tool for editorial work on ancient inscriptions.
