Annals of the International Geophysical Year, Volume 33: Results of Ionospheric Drift Observations describes the systematic changes in individual ionospheric observations during the International Geophysical Year (IGY). This book is composed of four chapters, and begins with a presentation of the general data on stations and the lists of publications concerning drift work during IGY/IGC. The next chapter contains the results obtained mainly by intercomparison of the time shift between fadings observed on three antenna separated by a distance of roughly a wavelength. These data are followed by a discussion of the results for a station, which has made the big effort of applying the correlation analysis as a routine. The concluding chapter highlights further results of intercomparison observations and tests, and a few stations'' results obtained with drift meteor trails determined by combinations of Radar- and Doppler-techniques, as well as the intercomparison of fieldstrength fluctuations of cosmic radio waves. This book is of great value to geophysicists and space scientists and researchers.

Geotectonics has a special place among the geological dis­ ciplines. In addition to ideas based on firmly established facts that constitute lasting scientific values, geotectonics, as a generalizing branch of geology, embraces broad con­ structions that link the planet''s deep interior with its sur­ face and are largely of a hypothetical character. The inter­ pretation of the most general matters of the structure and evolution of the globe varies not only from one generation of geologists to another, but even within one generation. The interpretation depends not only, and not so much, on the state of geological knowledge, as on the progress of the related sciences of geophysics and geochemistry. In trying to discover the deep-lying causes of tectonic processes, geotectonics has to unite the results of all the Earth sci­ ences, converting itself to some extent from a purely geologi­ cal science into a general physical geographic or geonomic science. The fluidity of the general ideas andthe need for joint consideration of the geological, geophysical, and geochemi­ cal data to substantiate these ideas are the main difficulties facing the author of a textbook on geotectonics. There is undoubtedly, however, a need for a manual of this kind, particularly now when the literature on the various problems of geotectonics has grown so great and so varied in content that it is very difficult for the experienced researcher, let alone the student, to find his way.
