From the new site's about page (accessed 2019-08-28):
Diotima serves as an interdisciplinary resource for anyone interested in patterns of gender around the ancient Mediterranean and as a forum for collaboration among instructors who teach courses about women and gender in the ancient world. This site includes course materials, the beginnings of a systematic and searchable bibliography, and links to many on-line resources, including articles, book reviews, databases, and images. Ross Scaife and Suzanne Bonefas launched this project in early 1995; since that time it has been developed mainly by Scaife, but with help and contributions from many quarters.
With the migration of the Stoa Consortium to the new servers at NYU in 2019, the updated Women's Classical Caucus copy of the Diotima website has become the official verion, and continues to be developed there, with the help of contributions from the community. They welcome contributions and other support from all scholars of gender in antiquity.
