Perhaps, the most significant volume on the background of the ancient city of Ephesus is being published by Harvard University Press at the start of the new year, with the title Ephesus: History, Archaeology, Architecture (ed. Athanasios Sideris).
Here is the description:
The introductory chapters present in detail the history and archaeology of the city from its Mycenaean past to its fall under the Seljuks in the 11th century CE. The heart of the volume is an analytic discussion of more than 60 buildings and monuments of the ancient city, supported by more than 370 architectural drawings, digital models, and color photographs. Also included are an extended chronological table, a visual and textual glossary (rendering the work accessible even to a nonspecialist public), a list of ancient sources, and a list of more than 600 cited works. This comprehensive volume is an indispensable companion to anyone studying the history and the archaeology of Asia Minor, and Hellenistic and Roman architecture more generally.
The only trouble I see, of course, is cost. This volume will sell for $80- putting it out of price range for many of us.
