A Directory of Archives useful for history of Archaeology Research.
Founded in 1879, the Hellenic Society continues to support research in the classical world. With subscriptions, it helped to finance travels and explorations into Greece and Asia Minor in the 1880s and provided grants for some of the early British School at Athens students.
The Society has made some of its archive relating to its founder George Macmillan, and one of the archaeologists it first supported, William Mitchell Ramsay, available online. The Society also holds the photographic collection of WJ Stillman, comprising historic images of Greece.
