Clarke, Dorothy B. Vitaliano, Virginia S. Neuschel, and others INTRODUCTION Extent of Coverage Geophysical Abstracts includes abstracts of technical papers and books on the physics of the solid earth, the application of physical methods and tech­ niques to geologic problems, and geophysical exploration. The table of con­ tents, which is alphabetically arranged, shows the material covered. Abstracts are prepared only of material that is believed to be generally a­ vailable. Ordinarily abstracts are not published of material with limited cir­ culations (such as dissertations, open-file reports, or memorandums) or of other papers presented orally at meetings. Abstracts of papers in Japanese and Chinese are based on abstracts or summaries !n a western language ac­ companying the paper. List of Journals Lists of journals published in Geophysical Abstracts 160 (January-March 1955, Bulletin 1033-A) and subsequent issues through 184 (January-March 1961, Bulletin 1146-A) have been compiled into a single list, which may be obtained by writing to the U.S. Geological Survey, Washington 25, D. C. Supplements to this master list have been published in each issue since Geophysical Abstracts 184. The following is an additional supplement that lists references cited in Geophysical Abstracts 186 that have not been listed previously. Akad. Nauk SSSR Lab. Gidrogeol.
