This lengthy two-volume work is part of a long-term Greek project to make foreign archives concerning modern Greek history more accessible to researchers in Greece. Professor Eleutherios Prevelakis, who passed away one year before the publication of these volumes, became the director of the Research Centre for the Study of Modern Greek History of the Academy of Athens in 1963. This position allowed him to conceive and carry through his program of collecting in microfilm form British archival material of relevance to modern Greece. The two volumes under review grew out of the work that he and Professor Merticopoulou conducted over many years in the archives of the Foreign Office and the Colonial Office, which are stored in the Public Record Office.
