Abstract

An exploratory study was conducted of elementary school children searching a full-text electronic encyclopedia on CD-ROM. 28 third and forth graders and 24 sixth graders conducted 2 assigned searches, one open-ended, the other one closed, after 2 demonstration sessions. Keystrokes captured by the computer and observer notes were used to examine user information-seeking strategies from a mental model perspective. Older searchers were more successful in finding required information, and took less time than younger searchers. No differences in total number of moves were found. Analysis of search patterns showed that novices used a heuristic, highly interactive search strategy. Searchers used sentence and phrase queries, indicating unique mental models for this search system. Most searchers accepted system defaults and used the AND connective in formulating queries. Transition matrix analysis showed that younger searchers generally favoured query refining moves and older searchers fovoured examining title and text moves. Suggestions for system designers were made and future research questions were identified

Abstract

Subject access plays an important part when plans are made for an on-line public access catalogue (OPAC). Therefore, current subject searching facilities in OPACs should be accessed carefully. These facilities include, amongst other things, phrase searching, keyword searching and class number retrieval. Users reaction have been instrumental in identifying certain shortcomings in subject access to OPACs. Points out certain shortcomings in subject access, as shown by a number of research projects undertaken during the past decade. Highlights aspects which could, in future, improve subject access in OPACs. This could be achieved by either enhancing content representation in the records within the OPAC data base or by enhancing the searchability and browsability of the OPAC. Considers whether the on-line catalogue will ever be a finished, perfect product, or achieve the universal, familiar uniformity experienced by users of the 20th century card catalogue.

Abstract

An eponym is an expression that consists of an individual's name plus a wor denoting some idea or thing associated with that person. The literatures of psychology and mathematics discuss the use of eponyms, and the presence of eponyms probably affects searches for information in those fields. In a study of 4.506 articles published in 1982, the author found that 4,4 percent of psychology article titles and 33,4 percent of methmatics article titles contained at least one eponym each. In psychology, 74 of 95 eponyms occured in articles that listed references to other works authored by the respective individuals associated with the eponyms. In mathematics, 688 of 1.105 eponyms occured in articles that cited other works having the respective names of the eponymous individuals in their titles. A comparison showed that 16,8 percent of psychology article eponyms and 39,9 percent of mathematics article eponyms exactly matched entries in at least one of their field's vocabulary lists

Abstract

Free text searching with keywords in a complete data store is not necessarily the best automatic retrieval method. There must be a proper classification of documents and concepts and the use of a proper classification system avoids problems of terminological deficiency. The dialogue search form makes the on-line catalogue a new information medium. A bibliographic unit must be created with as many search access points as possible, using verbal and classificatory search elements. Verbal search categories must include free text elements for individual search access requirements and a controlled vocabulary with syntactic connections. Classified data should consist of a universal classification system with clear structural notation for access and surface searching, together with several specialist subject classifications for differentiated documentation and retrieval. The universal classification needs no detailed subdivision: it serves mainly as a guide and entry to the detailed sub-systems

Abstract

For a variety of reasons, reclassification was a popular project in libraries in the 1960s. Although such projects have faded from the limelight, some of the reasons for doing them remain valid today, i.e., a need to cut processing costs, participation in cooperative ventures, the inconvenience caused by working with a collection split between two classification systems, and continuing changes in the Dewey schedules. This article compares the steps needed for reclassifying in a manual environment with those required when the library has an in-house computer system. The comparison shows how using the latter makes a reclassification project more feasible than it would be in a totally manual library. The article also discusses various issues associated with reclassification in an automated environment such as the problem posed by a frozen public catalog and the combining of reclassification and conversion projects.

Abstract

This paper examines library literature concerning the conflict in teaching cataloging, between education for librarianship and training for specific tasks performed in the library. The literature reflects fundamental trends in library education; balance between theory and practice, evolution from apprenticeship to graduate school and the role of cataloging in curricula. It has concerned six issues; practitioners as educators, differentiation of professional duties, centralization and cooperation, development of cataloging codes, technological change and anticipated professional functions. A more profound corollary issue is also addressed. Training prepares for the current environment; education prepares for change. The literature presents a dichotomous view, seeking resolution by balancing mutually exclusive elements. An historical perspective suggests a dialectical paradigm, a process of continuous interaction between opposing forces which produce a synthesis.

Abstract

The Lynn-Peterson Alternative Classification for Catholic Books and Kapsner's Catholic Subject Headings were devised in 1937 and 1942 respectively to meet a perceived need for cataloging and classifying Catholic theological materials. While not universally adopted by Catholic libraries, both schemas enjoyed considerable use until their decline beginning in the 1960s. Although the latest editions of both works are obsolete, 1954 and 1963 respectively, by choice or necessity a small number of libraries still employ either or both systems. This study questions the practical and economic feasibility of the continued use of either system in light of the movement toward universal bibliographic control as presented by OCLC et al. and the ongoing climate of ecumenism. Moreover, while the test data directly addresses two schemas, it indirectly brings into question the validity of any specialized or locally developed system.

Abstract

Originally published in 1979 as a title in the Outlines of Modern Librarianship' series this new edition has been expanded and updated in the light of recent developments in this rapidly developing field of librarianship, with particular reference to automation. As a consequence, this edition is substantially more than an outline of the subject. The authors take the reader through a comprehensive exposition of cataloguing - the definitions, arrangement and role of the catalogue: the history of its development; standardization and AACR2; the subject approach via pre-and post-coordinate indexing; analysis; filing rules and methods; the physical forms of the catalogue; the use of the computer in cataloguing; the role of networks; the management of cataloguing; and the relevance of book indexing. There is a detailed index, as well as a list of abbreviations and acronyms and a glossary of terms.

Abstract

The task facing the designers of information retrieval (IR) systems can be stated very simply: to produce the right kind of system with the right components at the right price. In practice, however, this task is greatly hindered by a lack of understanding and communication between the different groups of specialists working on different parts of the system - a problem exacerbated by the fact that each group uses a different jargon, so preventing the exchange of ideas and expertise. There is thus a need for a comprehensive, unified overview of practical computer-based retrieval, and this book provides one. It describes the various parts and their alternative forms, the relationships between them and how these affect the working of the system as a whole. Topics covered include: user, software, knowledge representation, expert systems, database management systems, hardware, user interfaces.
