- Abstract
- Calvin Mooers' work toward the resolution of the problem of ambiguity in indexing went unrecognized for years. At the time he introduced the "descriptor" - a term with a very distinct meaning-indexers were, for the most part, taking index terms directly from the document, without either rationalizing them with context or normalizing them with some kind of classification. It is ironic that Mooers' term came to be attached to the popular but unsophisticated indexing methods which he was trying to root out. Simply expressed, what Mooers did was to take the dictionary definitions of terms and redefine them so clearly that they could not be used in any context except that provided by the new definition. He did, at great pains, construct such meanings for over four hundred words; disambiguation and specificity were sought after and found for these words. He proposed that all indexers adopt this method so that when the index supplied a term, it also supplied the exact meaning for that term as used in the indexed document. The same term used differently in another document would be defined differently and possibly renamed to avoid ambiguity. The disambiguation was achieved by using unabridged dictionaries and other sources of defining terminology. In practice, this tends to produce circularity in definition, that is, word A refers to word B which refers to word C which refers to word A. It was necessary, therefore, to break this chain by creating a new, definitive meaning for each word. Eventually, means such as those used by Austin (q.v.) for PRECIS achieved the same purpose, but by much more complex means than just creating a unique definition of each term. Mooers, however, was probably the first to realize how confusing undefined terminology could be. Early automatic indexers dealt with distinct disciplines and, as long as they did not stray beyond disciplinary boundaries, a quick and dirty keyword approach was satisfactory. The trouble came when attempts were made to make a combined index for two or more distinct disciplines. A number of processes have since been developed, mostly involving tagging of some kind or use of strings. Mooers' solution has rarely been considered seriously and probably would be extremely difficult to apply now because of so much interdisciplinarity. But for a specific, weIl defined field, it is still weIl worth considering. Mooers received training in mathematics and physics from the University of Minnesota and the Massachusetts Institute of Technology. He was the founder of Zator Company, which developed and marketed a coded card information retrieval system, and of Rockford Research, Inc., which engages in research in information science. He is the inventor of the TRAC computer language.

- Abstract
- Traditional cataloging support services such as typing and filing are gradually being eliminated in favor of more sophisticated skills. Library staff members who are specialized in imminently obsolete skills must be re-educated to become productive participants in the "Golden Age" of technology. The Catalog Management section at the Iowa State University Library is attempting to make this process painless and exciting for all of its employees.

- Abstract
- Duplicate records is a familiar problem in bibliographic databases. The problem is obvious when a union catalogue is established by automatically merging two or more separate and independent source of catalogue information. However, even in systems with on-line cataloguing and access to previous records, duplication is a problem. Author / title search search prior to cataloguing does not cut duplication to zero. A great deal of effort has been put into developing methods of duplicate detection. A major problem in this work has been efficiency. Particularly in the on-line setting is this of importance. Most studies have dealt with book and article material. The Research Libraries Group Inc. has described matching algorithms also for films, maps, recordings, scores and serials. Various methods of detecting duplicates will be discussed.

- Abstract
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

- Abstract
- Paper presented at a symposium on 'Implementing the Art and Architecture Thesaurus (AAT): Controlled Vocabulary in the Extended MARC format', held at the 1989 Annual Conference of the Art Libraries Society of North America. The only way to get bibliographic records on to campus on-line library catalogues, and slide records on the national bibliographic utilities, is through the use of MARC. Discusses the importance of having individual slide and photograph records on the national bibliographic utilities, and considers the obstacles which currently make this difficult. Discusses mapping to MARC from data base management systems.

- Abstract
- Information management or information resource management is a management philosophy or approach which has as its goal the management of information as an asset, as a resource of strategic importance to the organisation, analogous entirely to the planning and administration of human resources, financial resources, or any other asset. Discusses the relationship between records management and archives and information resource management. Suggests an alternative strategy in which specific, achievable, pragmatic objectives are the focus emphasising that the future of the archival profession in the information age rests upon their satisfactory resolution.

- Abstract
- The idea of computing with concepts as mathematicians manipulate variables in equations goes back at least as far as G. W. Leibniz (1663). Leibniz dreamed of a universal calculus, an ambiguity-free language, with which scholars could communicate ideas with mathematical precision. George Boole, in his investigation of the laws of thought, contributed to the realization of this idea by developing a calculus of classes (1847). A modern visionary who saw a practical application of Boole's work and further contributed to the idea of communicating by "computing" was Mortimer Taube (1910-1965), a member of the Library of Congress staff from 1944 to 1949 who later founded Documentation, Inc. He proposed communicating with a mechanized information store by combining concepts using the Boolean operators, AND, OR and NOT. The following selection contains one of the first presentations of a technique Taube called "coordinate indexing" and what later has come to be called "post coordinate indexing" or Boolean searching. This selection is interesting an three counts. It is interesting first of all because of its early date-1950. Though the idea of coordinate indexing had been anticipated in manual systems of the punched card sort, these systems were limited, relying for the most part an repeated application of the AND operator. To conceptualize the full power that could be achieved by Boolean search strategy in mechanized systems was an imaginative step forward. Second, the selection is interesting insofar as the idea of coordinate indexing is couched, indeed nearly hidden, in a somewhat ponderous essay an the compatibility of universal and special classifications and the merits of different methods of information organization. Ponderous though it is, the essay is worth a careful reading. The perspective it gives is enlightening, a reminder that the roots of information science reach far back into the bibliographic past. The third and perhaps most interesting aspect of this selection is that in it Taube looks beyond the technique of coordinate indexing to envisage its implications an bibliographic organization. (Now more than thirty years later we are still attempting to understand these implications.) What Taube saw was a new method of bibliographic organization, which, not ingenuously, he observed might seem almost bumptious in the face of a two thousand year history of organizing information. This "new" method was, however, being proposed elsewhere, albeit in different guise, by S. R. Ranganathan (q.v.) and his school. It was the method of organizing information using abstract categories called fields or facets. These categories, unlike those used in the great traditional classifications, were not locked in procrustean hierarchical structures, but could be freely synthesized or combined in indexing or retrieval. In short, Taube's voice was among those at midcentury supporting the move from enumerative to synthetic subject approaches. The fact that it was an American voice and one especially weIl informed about bibliography and computers is perhaps what led Jesse Shera to refer to Taube as "the Melvil Dewey ... of midtwentieth century American Librarianship," one who was able "to weld successfully conventional librarianship and the then-emerging information science."
