Mainly sources with climatic data, summarized over a period, were selected for the bibliography. In addition, the years from 1940 to the termination date (April 15, 1960) were emphasized in choosing sources. The initials DWB, DLC and DN-HO used in the abstract titles refer to the Weather Bureau Library, the Library of Congress and the U.S. Navy Hydrographic Office Library all in Washington, D.C. Preparation of these abstracts was done in the Foreign Area Section of the Office of Climatology. All scales with brackets are measured with a natural map scale indicator from maps with latitude lines and are only an estimation. Those scales without brackets in the abstracts are given on the climatic maps or a legend scale provided. On maps without parallels, latitude lines were estimated and a natural map scale used to obtain an approximate map scale; these are indicated by parenthesis. (Author).
