His first book, "Introduction to the Theory of Seismology", was published by the Cambridge University Press in 1947 and has been a standard text for seismology ever since. The third edition was published in 1975 and Turkish, Chinese, and Russian translations were published in 1960, 1965, and 1965 respectively. Two other books closely related to his teaching at Sydney, "Introduction to the Theory of Dynamics" and "Introduction to the Theory of Mechanics" were published in 1948 and 1949. An eighth edition of the latter was published in 1971. His short monograph, "Seismology", was published by Methuen in 1954. The International Institute of Seismology and Earthquake Engineering published his notes for a lecture course on theoretical seismology in 1972. His last book, The "Earth's Density", was published in 1975; it covers a wider range of geophysics than its title would suggest because the problem of the Earth's density distribution is so intimately related to seismological information on the interior of the Earth.
