In my last Bibliography (J.H.S. xxxix. 209 ff.) I attempted to cover the three and a half years from July 1915 to December 1918 inclusive, though I was only too well aware that, under the conditions of the period of war and armistice, I could not claim completeness for my record. In the present article I deal primarily with the years 1919 and 1920, but I have inserted references to a number of books and articles which actually appeared earlier though they did not become accessible to me until the years under review. Excavation has not yet been renewed on anything like the pre-war scale and the number of Greek inscriptions published for the first time is correspondingly small, but gratifying progress has been made in many directions in the restoration of mutilated texts and the fuller interpretation and utilisation of documents already known. The reader who glances even cursorily through the following pages will, I hope, be struck, despite the compression necessitated by considerations of space, by the vitality and interest of the study to which they relate, and by the many-sided contribution it has made to the understanding of Hellenic language, literature, religion and history.
