This volume, containing orations 41-61, is the last of four volumes intended to replace the previous Oxford Classical Text of Demosthenes, begun in 1901, in the light of more recent scholarship. It is based on a thorough study not only of the medieval manuscript tradition but of papyrus fragments, some of them published only in the past few years, and of quotations in other authors, many of which have not previously been used for this purpose. All this information is presented in notes in Greek and Latin, which not only allow convenient access to evidence for the text but also provide references to ancient and medieval interpretations of the orations. There is an English preface.
