The local scripts of archaic Greece : a study of the origin of the Greek alphabet and its development from the eighth to the fifth centuries B.C. - Jeffery, Lilian Hamilton (Clarendon Press, 1961)
"Accepted as a thesis for the degree of doctor of philosophy at Oxford in 1951. The material of parts I and II has undergone little alteration ... In part III the catalogues of inscriptions have been expanded to include material published since 1951, and parts of the text have been modified or rewritten."
