We just added links to two databases concerning the classical world:
An evolving online research tool to facilitate the study of agonistic networks in the ancient, post-classical world. It is part of a wider research project on the history of athletic and other agonistic festivals from 300 BC-AD 300. (see above under about). This website aims to provide an intuitive database of the many contests of the Greek world, and of the athletes, performers and other participants in these contests. (from description on-site).

In addition, there is a new link to an open access journal dedicated to the Byzantine period and research- The Byzantine Review
