Abstract

Since an increasing variety of electronic information media and their hybrid developments is available in libraries, a unifying concept is needed to obviate the constant creation of new fonds and catalogues, and the futile search for the illusory 'definitive' electronic product. Suggests that although the Internet provides only a superficial integration of various electronic media, its central concept is the unifying one of hypertextuality, whose 4 main elements are the following: multilinearity; hypermediality; integrability; and interactiveness. Explains these ideas, and describes also Philip Barker's suggested 4 categories of the technologically advanced library: multimedia, electronic, digital and virtual. Makes suggestions to help librarians progress towards the virtual library

Abstract

To enhance descriptions, cataloguers can add 'enriching' words or phrases to titles, or introduce content-enriched access features to aid subject-based research. Additional and natural language subject headings designed to support, though not replace, controlled language headings can result in enhanced indexing. Analytical cataloguing and double indexing are 2 other means by which readers can gian access to additional bibliographic data. Also examines how online research tool effectiveness can be enhanced by a system of automatic links between descriptors

Abstract

Reports an empirical study at the Queriniana Civic Library, Brescia, of interaction betwee researchers and printed catalogues during bibliographic data retrieval. The study sought to ascertain frequency of catalogue use; research success rate and time taken; and to identify user profiles. Data were obtained by a mixture of questionnaires, interviews and direct observation. Findings showed that 64% of the catalogue users were female; 70% were aged 19-30; 65% were university students or had good school grades; and hardly any were working class. University students preferred keyword access. 50% or all searches were successful. Most search failures related to subject catalogues, which usually required more time. Provides statistics on time spent in research

Abstract

Psychologists, philosophers and linguists analyse concepts and investigate their relationship to words. Concepts are also relevant to the issue of bibliographic classification, i.e. "catagorisation". Examines from a chronological point of view the various theories for the analysis and organisation of concepts ranging from the Vickery developed in 1954, to Austin's hypotheses, to Ranganathan's "fundamental categories" and the contribution made by CRG, the Classification Research Group. Illustrates other approaches to categorisation such as Farradane's (relationship between couples of concepts) and calls for a closer study of categories and concepts.

Abstract

Proposes a new experimental methodology for evaluating the results of library research from the user's viewpoint. Illustrates the theory by comparing the efficacy of information retrieved from 2 document catalogues, identical except that one is alphabetical and the other numerical/verbal. The methodology utilises the concept of 3 dependent variables: 'promising references retrieved' by the researcher; 'documents read'; and 'documents cited'. Claims that the retrieval effectiveness of the techniques outlined compares favourably with that of W.S. Cooper's methodology

Abstract

Analyses the functions and applications of the computer program Iride 1.01 (CDS-ISIS Micro), distributed free to Italian schools since 1994 and developed jointly by Florence's teaching documentation library, regional education institutes, the European Education Centre and other bodies. Iride can handle a broad range of information resources, including grey literature, audiovisual materials, and CD-ROMs. Students and teachers can use Iride to design research programmes, and to create their own database catalogues. iride is closely linked with hands-on training for school libraries. Provides a technical schedule of Iride functions

Abstract

Describes a proposed system for helping public library users, in praticular students, in their document searches. The system would directly involve users in compiling cards that indictae the various library sources (encyclopedias, books, newspapers, magazines, etc.) from which they retrieved bibliographic data. These cards would then be used to create a search path catalogue having 2 sections: general research topics; and keywords. Subsequently the librarian would form a database from this information. Such a system would not only benefit other researchers but also help the library to plan acquisition and rationalise its document arrangements. The scheme won 3rd prize in an open competition designated 'La biblioteca desiderata' (The kind of library we want), promoted jointly by the Milan Province Cultural Office and Biblioteche Oggi

Abstract

Looks at current research into the cognitve aspects of information search and retrieval by library users. Illustrates the theoretical approach to indexing procedures, developed from a cognitive viewpoint, and outlines the basics of cognitive epistemology. Discusses the work of psychologist W. Kintsch and linguist T.A. van Dijk on the mechanics of information acquisition, text comprehension and text production. Analyses the linguistic theory of meaning, and summarises the main criticisms of the cognitive approach, as propounded by B. Frohmann, B.C. Brookes, R.L. Derr and D. Rudd, among others

Abstract

Looks at how new information search and retrieval technology is creating the so-called desktop library. Current full text retrieval (FTR) systems have extended search operations to the whole content of an electronic document. Research can be not simply Boolean but also by natural language processing (NLP). A matter of concern to librarians is the ability of the latest FTR search angines to construct automatic indexes. In the field of network information discovery and retrieval (NIDR) the 2 most important protocols for librarians are the international SR / Z39.50 standard and http. Describes the differing operations of FTR and NIDR as they affect the end-user

Abstract

The 'Guida all'indicizzazione per soggetto', the outcome of the work of the GRIS collaborative project of Italian research and academic libraries on subject heading schemes for Italian libraries, was published in 1996, though not in a definitive form. Presents some notes as a contribution to the definitive version, particularly section 3. The latter is concerned with the control of terms, including the analysis of categories, the morphology of terms and the structure of vocabulary

Abstract

Analyses the technical features of the 5 main search fields of the OPAC run by Bologna University's interlibrary centre (CIB), part of the National Library Service (SBN). The CIB links about 100 academic and civil library collections on the humanities, social sciences, and science subjects. With the aid of Home Page / Helpline displays, examines how OPAC search procedures are carried out by author, title, subject, ISBN, or single library. Also explains the data filtering methods used. The CIB will soon broaden its OPAC search strategies by adopting the Florence University library OPAC research structure

Abstract

EasyWeb is an Italian amde research program for library/archive users that allows simple access to Internet catalogue data via the WWW. The software is based on CDS/ISOIS and is currently available on the UNIX operating system with Intel 486 and Pentium processors. EasyWeb has been tested on the following operating systems: Olivetti, Sco, Novell UnixWare, Linux 1.2.13, Slackware with iBCS2; and in the new 1996 version will be installed on all other UNIX platforms (Solaris, HP, etc.). Names Italian academic bodies with EasyWeb installations and provides an Internet address
