Abstract

Reports results of a week long sample observation of card catalogue consultation by library users. Subsequent questioning of users about the purposes for which they consulted the catalogue revealed that the classified catalogue is not used as all and the author and title catalogue are consulted to the maximum. It is also found that 80% of the consultations of card catalogue are to locate documents, 10% is to make comprehensive searches for references on a topic and rest for miscellaneous purposes

Abstract

A study was done to test the effectiveness of retrieval using title word searching. It was based on actual search profiles used in the Mechanized Information Center at Ohio State University, in order ro replicate as closely as possible actual searching conditions. Fewer than 50% of the relevant titles were retrieved by keywords in titles. The low rate of retrieval can be attributes to three sources: titles themselves, user and information specialist ignorance of the subject vocabulary in use, and to general language problems. Across fields it was found that the social sciences had the best retrieval rate, with science having the next best, and arts and humanities the lowest. Ways to enhance and supplement keyword in title searching on the computer and in printed indexes are discussed.

Abstract

Describes the application of the CDS/ISIS software package (version 1.0) for the creation of a subject index to the National Union Catalogue of Scientific Periodicals in India (NUCSSI) data base. The subject index helps the user to find the titles available under particular subjects covered by the data base. The subject index has a subject code, UDC number and subject heading selected from the key title of the periodical

Abstract

Contends that quality in a catalogue is crucially related to its capability to deliver the services it is intended to provide: enabling a user to find a book of which the author, title or subject is known; and to show what the library has be a given author or on a given subject or in a given kind of literature. Describes changes in recent years which have implications for the choice of a retrieval system for library users. Discusses 2 types of problems experiences by users wanting to harness the potential of OPACs. These include: problems with the system itself. Describes the role of the cataloguer today which is essentially to interface the users with the retrieval system

Abstract

Describes the function and problems of the traditional card catalogue compared with a computerised catalogue. Examines library cataloguing with the computer, linked to rules for subject cataloguing, as well as the oppor-tunities offered by computerised title entries, the transfer of data from outside, data base structure and indexing. Also looks at techniques for searching catalogues with computers, including search rules with Boolean operators, searches restricted to specific fields of free search in all fields for a vague concept. Other topics cover the essential principles of the OPAC, its information functions, mail box function and hardware configuration.

Abstract

Summarises the findings of apilot project at the Austrian Planning centre for Academic Libraries to assess the ÖZDB-Compactsystem on CD-ROM, the first system for serials on CD-ROM to be used in the German speaking countries. The system makes available 47,713 titles from Vienna, Graz, Linz and Salzburg university Libraries locally on an Apple Macintosh computer. The firm was able to provide information about CD-ROM and to supply the hardware for the 6-week project. The whole programme was prepared centrally. It was possible to call up records both by title and by institution responsible, and of the desired degree of specificity. The systems allows the additional advantages option of CD-PAC (Compact Disc Public Access Catalogue) wich can be used in conjunction with the already established BIBOS system.

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

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 human process of determining bibliographic data from title pages of monographs is complex, yet systematic. This paper investigates the intellectual process involved, in conceptual and logical levels, by proposing a model of the expert system for determining title proper as the first element of the first area in ISBD. It assumes that the title page of a monograph consists of more than one block of character or graphic representation. Each block has its physical and content characteristics and can be separated from other blocks by separators. Three categories of expert knowledge are identified, and the system model is discussed along with its individual system component. It applies the "list" concept for the system data structure and addresses the potentiality of this conceptual model.

Abstract

This study examines the interrelationship of the rules on parallel title in AACR2. What emerges from the analysis are two principles that were utilized in the codification of the rules: (1) a principle of interrelationship (i.e. transcribing a data element in its relationship to other data elements); and (2) a principle of structured format (i.e. transcribing a data element in a prescribed order). A graphic representation of the possible combinations and positions of the data elements of descriptions in the title and statement of responsibility area (Area 1) shows that the present rules do not ensure consistency in bibliographic recording.

Abstract

This article reports on a comparison of the postcoordinate retrieval effectiveness of two indexing languages: LCSH and PRECIS. The effect of augmenting each with title words was also studies. The database for the study was over 15.000 UK MARC records. Users returned 5.326 relevant judgements for citations retrieved for 61 SDI profiles, representing a wide variety of subjects. Results are reported in terms of precision and relative recall. Pure/applied sciences data and social science data were analyzed separately. Cochran's significance tests for ratios were used to interpret the findings. Recall emerged as the more important measure discriminating the behavior of the two languages. Addition of title words was found to improve recall of both indexing languages significantly. A direct relationship was observed between recall and exhaustivity. For the social sciences searches, recalls from PRECIS alone and from PRECIS with title words were significantly higher than those from LCSH alone and from LCSH with title words, respectively. Corresponding comparisons for the pure/applied sciences searches revealed no significant differences
