MONO91 Indexes Compiled by Machine chapter Mary Elizabeth Stevens National Bureau of Standards punched card form, it has also permitted the establishment of a circulation control system, the publication of overdue notices and reading lists, and the eventual institution of a computer retrieval program'1 (Durkin and White, 1961 [173]; White, 1963 [638]). Heiliger reports for the library of the new Chicago Campus of the University of Illinois as follows: "The type of bibliography the computer can produce does make greater use of LC card information than do present card catalogs. With the computer programmed with a set of library filing rules and a set of symbols that describes for the computer the various parts of the bibliographic unit, it can print-out, for instance, a list of books published in a given country, between certain years, on a certain subject (or combination of subjects), that are illustrated and have bibliographies. It will also be possible to permute on individual items in LC subject headings in the same fashion that Chemical Titles does on titles. This index has been dubbed POSH (permuted on subject headings)." 1/ Some recent experimental work at Inforonics, Inc. puts major emphasis on by- product data generation, beginning with the actual preparation of manuscripts for publi- cation. Tape typewriter processing of manuscript for journal articles is being studied from the point of view of producing machine-usable text. This text, together with coded identification of the separate items in the text, is so prepared that computer programs can produce from the single-input automatic typesetting tapes for the article itself, author and subject index entries, and the like. Computer text transformations can also produce entries for citation indexes, abstract journals and search files (Buckland, 1963 [83, 84]). Other computer-produced indexes or special indexes involving compilation rather than selection by machine include indexes to Nuclear Science Abstracts (Day and Lebow, 1960 [151]), the Current List of Medical Literature (Chonez, 1960 [116, 117, 118]), the Retrieval Guide to Thermophysical Properties Research Literature 2/ and the Research and Development Abstracts of the USAEC (Sherrod, 1963 [541]). At the Atomic Energy Commission also, a modification of this RDA computer program is used for author, corporate author, number and subject indexes for the Engineering Materials List, which includes announcements of blueprints and drawing5.[OCRerr]3/ In several instances, machine processing capabilities are used for permuted listings under various assigned indexing terms.4/ Special cases of machine permutation operations involve compilation and organization of chain indexes, used to reflect the various key entries in faceted classification systems (Dowell and Marshall, 1962 [159]; Foskett, 1962 [199]; Olney 1963 [458]). 1/ 2/ 3/ 4/ Heiliger, 1962 [259], p. 475.
