429 published library catalogues (in book form) from about 1960 to 1981, mostly of American libraries. Listing arranged by 33 general categories and then alphabetically. Each numbered entry discusses the subject coverage and structure of the catalogue. Little is said about the actual form of the publications; presumably most are of the photocopied-card-catalogue-card variety. The introduction discusses different types of catalogues and the probable effects of computer technology (with the necessity of standardization), concluding that "variety of Catalogues that resulted from the great philosophical debates of the ninteenth century will be unlikely to survive the new technology..." p.xvi. With index.
