    Abstract
    Reviews the cumulative index to LISA, the leading English language abstracting journal on librarianship and information science and maintains that the index is a vital reference tool for those who do not have access to an on-line search service. Dascribes the index which is arranged in sequences of name and subject. Maintains that the introduction could be longer as the name index in particular requires more explanation, and illustrates by means of axamples. Lists strengths and weaknesses of the name index. Asserts that the subject index will receive greater use and warrants some explanation which is not provided. Suggests that the value of chain indexing is negated by divorce from classification. Affirms the enormous value of the work as an indispensable reference tool

    Abstract
    Julia Pettee's contribution to classification theory came about as part of her work an subject headings. Pettee (1872-1967) was for many years librarian of the Union Theological Seminary in New York and was best known for the classification system she developed for the seminary and as the author of the book Subiect Headings. She was one of the first to call attention to the fact that there was a classification system in subject headings. It was, as she put it, "completely concealed when scattered through the alphabetical sequence" (p. 98). On the other hand, she recognized that an index entry was a pointing device and existed to show users specific terms. Index terms, unlike subject headings, could be manipulated, inverted, repeated, and stated in as many words as might be desired. The subject heading, she reiterated, had in it "some idea of classification," but was designed to pull together like material and, unlike the index term, would have limited capability for supplying access by way of synonyms, catchwords, or other associative forms. It is interesting that she also thought of the subject heading in context as forming a three-dimensional system. Logically this is the case whenever one attempts to reach beyond the conventional hierarchy as described an a plane surface, and, in fact, thought out as if the classification were an a plane surface. Pettee described this dimension variously as names "reaching up and over the surface ... hands clasp[ing] in the air" from an individual term (pp. 99-100). Or, in other context, as the mapping of "the many third-dimensional criss-crossing relationships of subject headings." (p. 103) Investigations following Pettee's insight have shown the nature and the degree of the classification latent in subject headings and also in the cross-references of all indexing systems using cross-references of the associative type ("see also" or equivalent terminology). More importantly, study of this type of connection has revealed jumps in logic and meaning caused by homographs or homonyms and resulting in false connections in classification. Standardized rules for making thesauri have prevented some of the more glaring non sequiturs, but much more still needs to be done. The whole area of "related terms", for example, needs to be brought under control, especially in terms of classification mapping.

    Abstract
    To those outside the field of library science, the name Melvil Dewey (1851-1931) is virtually synonymous with library classification. To those in the field, Dewey has been recognized as the premier classification maker. His enormously successful system (i.e., successful in terms of the wide adoption of the system around the world for over one hundred years) has now undergone nineteen editions. The Dewey Decimal Classification has been translated into more than twenty languages and is the most widely adopted classification scheme in the world. Even in its earliest manifestations, the Dewey Decimal Classification contained features that anticipated modern classification theory. Among these are the use of mnemonics and the commonly applied standard subdivisions, later called "common isolates" by S. R. Ranganathan (q.v.), which are the mainstays of facet analysis and synthesis. The device of standard subdivisions is an indication of the recognition of common aspects that pervade all subjects. The use of mnemonics, whereby recurring concepts in the scheme are represented by the same notation, for example, geographic concepts and language concepts, eased the transition of the Dewey Decimal Classification from a largely enumerative system to an increasingly faceted one. Another significant feature of the Dewey Decimal Classification is the use of the hierarchical notation based an the arabic numeral system. To a large extent, this feature accounts for the wide use and success of the system in the world across language barriers. With the prospect of increasing online information retrieval, the hierarchical notation will have a significant impact an the effectiveness of the Dewey Decimal Classification as an online retrieval tool. Because the notation is hierarchical, for example, with increasing digits in a number representing narrower subjects and decreasing digits indicating broader subjects, the Dewey Decimal Classification is particularly useful in generic searches for broadening or narrowing search results. In the preface to the second edition of his Decimal Classification Dewey explained the features of his "new" system. The excerpt below presents his ideas and theory concerning the rational basis of his classification, the standard subdivisions, the hierarchical notation based an decimal numbers, the use of mnemonics, the relative index, and relative location. It also reflects Dewey's lifelong interest in simplified spelling.

    Abstract
    The Deep Structure Indexing System is based on: (1) a set of postulated elementary categories of the elements fit to form componentes of names of subjects; (2) a set of syntax rules with reference to the categories; (3) a vocabulary control tool such as Classaurus; (4) a set of indicator digits to denote the categories and their subdivisions; and (5) a set of codes to denote a few of the decisions of the indexer. Names of subjects formulated on the basis mentioned above are input to a set of computer programs to generate several different types of subject index entires. This paper describes briefly the Deep Structure Index System

    Abstract
    In May 80 the joint working parties on the Dutch National Bibliography and the Dutch National Bibliographical Centre published their final report containing proposals for a national bibliography in the Netherlands based on Brinkmann's catalogue of books. In view of the limited number of terms used in the subject index of Brinkmann's catalogue it was proposed to adopt the thesaurus of headings developed by the Netherlands Bibliotheek en Lektuur Centrum with the addition of UDC and SISO classification numbers to each entry. A test-run has identified a core of some 3.500 headings which will be input into the database to provide a subject index to the bibliography. The system will become operational on 1 Jan 81

    Abstract
    The main purpose of the study was to determine if the online catalog can function both as a dictionary and classified catalog without requiring additional time or intellectual effort on the part of the cataloger. A total of 1842 MARC bibliographic records listed in the 370-379 classified section of American Book Publishing Record were studied. These records displayed 2735 subject headings. Of these, 1491 (55%) had a Library of Congress classification number linked to them. An alphabetical and classified index was created using primary subjects and their related classification numbers. While such an index could be a useful browsing device if integrated into an online catalog, creating a bona fide classified catalog would require assigning classification numbers to the secondary subject headings.
