Per the home page: “The Melammu Project investigates the continuity, transformation and diffusion of Mesopotamian and Ancient Near Eastern culture from the third millennium BCE through the ancient world until Islamic times.

As per the website, “Nestor is an international bibliography of Aegean studies, Homeric society, Indo-European linguistics, and related fields.

Perhaps the most well known, and helpful, online resource for classicists and ancient historians is Perseus. It is a joint project, originally started at Tufts University, which transcribes ancient texts, in both the original language as well as (often) an English translation. Most of the authors and works cited on our website can be found on Perseus, allowing you to read for yourself the evidence upon which we have built our arguments. It also contains catalogues of texts from other eras, as well as a collection of archaeological materials which are searchable.
The STOA website is a blog offering news, overviews of vacancies that are of interest to students of the ancient world, and more.
