This should prove an extremely valuable reference book for schools, libraries, editorial offices, writers' bookshelves --as well as a treasurehouse of information and suggestion for everyone interested in words and their meanings and the development of a folk speech. Slang is of wide psychological, sociological and linguistic interest. There exist various dictionaries of slang, glossaries of the underworld, foreign collections of ""Americanisms"". This purports to be the first thesaurus of sub-standard language, irrespective of source, with words grouped under categories. Part I deals with general slang and colloquialism; Part II, special slang growing out of such backgrounds as radio, theatre, sports, etc. In alphabetical order the authors have grouped words and phrases that are synonymous. And a very complete index makes it possible to locate a word in its various meanings and applications, under various headings, while suggestions for other possible locations of allied material are given at the end of each special section. 1174 pages inevitably make a heavy book, but type is reasonably good, and page layouts make for ready use.
