Archaeology in Greece Online combines the Chronique published annually in the BCH by the French School at Athens, and Archaeology in Greece published as part of the annual Archaeological Reports by the Society for the Promotion of Hellenic Studies and the British School at Athens (which continues to appear in print in a new review format). The project is managed jointly by the French School at Athens and the British School at Athens: data processing is divided by region and reflects the traditions, history and research foci of the two schools. Texts are thus either in English or in French, but the search engine draws on the entire database regardless of language.
