The American School of Classical Studies at Athens was founded in 1881 to provide American graduate students and scholars a base for their studies in the history and civilization of the Greek world. Today it is still a teaching institution, providing graduate students a unique opportunity to study firsthand the sites and monuments of Greece. The School is also a superb resource for students and senior scholars pursuing research in many fields ranging from prehistoric to modern Greece, thanks to its internationally renowned libraries, the Blegen, focusing on all aspects of Greece from its earliest prehistory to late antiquity, and the Gennadius, which concentrates on the medieval to modern Greek world, as well as the Malcolm H. Wiener Laboratory for Archaeological Sciences.
