Annals of the International Geophysical Year, Volume 48: Bibliography and Index contains bibliography of articles published in connection with the International Geophysical Year (IGY). The preparatory and operational phases of the IGY occupied nearly a decade and the data accumulated in the many scientific disciplines by workers in some 67 countries will provide material for publication for many years. The references have been assembled from information supplied by a wide variety of sources. These references have been grouped into 21 sections, of which Sections I-XIV followed the discipline grouping adopted during the IGY. Within each section references have been arranged in alphabetical order according to the name of the principal author. Anonymous articles are listed at the end of each section, again arranged in alphabetical order by title. In the scientific literature, author's names originally printed in Cyrillic symbols sometimes appear with several different spellings because of the use of different transliteration systems. In the present Bibliography an attempt has been made to achieve consistency by using the same transliteration system throughout. This book will prove useful to geophysicists and researchers who are interested in the accomplishments of the International Geophysical Year.

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.

Annals of the International Geophysical Year, Volume 28: Tables of IGC Cosmic Ray Data, Part III contains tabulations of International Geophysical Cooperation's cosmic ray activity data. This book includes lists of stations and investigators from whom further information on the cosmic ray apparatus can be obtained. In order to prepare the data on the following pages for publication, the data are first put on punched cards and then checked for correctness essentially by repunching, thus minimizing errors of transcription and also facilitate some computations which have been made with some of the data. Tabulating machines are then used to print the data on standard forms and the data are photographed for reproduction. As a further insurance against errors, carbon copies of the data sheets are sent to all investigators to be checked. The data marked as verified in the table of contents have been returned to the data center and the corrections made. This book will prove useful to geophysical researchers.
