- 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
- Presents the basic ideas underlying fuzzy set theory, developed by Zadeh in the 1960s, which has important appplications in information retrieval and documentation. A fuzzy information retrieval system is much less restrictive that a Boolean model, since results can be arranged according to degree of similarity. Another application of the theory concerns the use of linguistic quantifiers; this type of solution is well adapted to retrieval systems designed for direct operation by end-users. Illustraes with examples fuzzy set algebra, operation, relationships, logic and reasoning

- 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

- The head of electronic engineering at Florence's Universita degli Studi describes how the department has used digitized imaging and computer reconstructions to aid the restoration and preservation of works of art in museums such as the Uffizi. The dapertmant shares in the MAN (Metropolitan Area Network) Toscana Telecoms project, whose applications include remote access to libraries and museums; and it also takes part in the EU MUSA project, which developed the Vasari (Visual Arts Systems Archiving Retrieval Images) scanner, and in the RAMA (Remote Access to Museum Archives) scheme

- Abstract
- In relation to indexing, one of the chief implications of cognitive epistemology is the necessity for redefining knowledge representation concepts for information filing and retrieval purposes. Such a redefinition involves abandoning the traditional, hierarchical, closed-structure classification model. Considers the following in detail: a semiotic critique of classification principles; Ranganathan's classification theory; Ranganathan and cognitive epistemology; and some reflections on the DDC and the Bliss Bibliographic Classification

- As a solution for networked information retrieval the ISO has adopted the SR/Z39.50 protocol. Debate however continues, particularly as regards OPAC, on the relatice merits of Z39.50 and the facilities afforded by the WWW, which based on the http protocol. Examines the features of these 2 solutions for OPAC, and also describes the ARCA project, set up in 1995 with finance from the EC Libraries programme to implement the Z39.50 protocol

- Abstract
- Examines the structure and functions of the Bavarian regional electronic network, the Bibliotheksverbund Bayern (BVB), linking more than 60 academic and sceintific libraries. Utilising the Sokrates automation program, the system promotes close cooperation in technical and management matters, especially in relation to acquisitions, cataloguing, data retrieval and loans. BVB projects include the following: reconversion and digitization of printed catalogues, starting with the Bayerische Staatsbibliothek; automation of remote lending operations (within the national DBV-OSI scheme); the Elektra document order and supply service; and an electronic full-text document project

- 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
- 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.

- Abstract
- The Stuttgart University of Library and Information Studies has collected interesting data from a questionnaire based study of CDS/ISIS retrieval system application. Replies from 34 worldwide users, all with Internet access, suggest that CDS/ISIS is mostly used with stand-alone PCs, and that there is much interest in the possible use of CDS/ISIS on UNIX platforms. In 19 cases, CDS/ISIS application s relate to library functions, while in the areas of technology, medicine and the environment most databases are CDS/ISIS-structured and designed for local or internal use. The study also provides data on areas such as CDS/ISIS user groups and development programmes
