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

Abstract

Bibliography' s claim to be a discipline is founded on its specific and exclusive concerns with knowledge organization structures and with the logical tools needed for indexing procedures. Discusses in a historical context the theoretical bases of bibliography, exploring such themes as the problems of author/reader communication and the abandonment of university accepted document classification criteria. Suggests that probably the only way to restore bibliographic communication is to adopt cognitive and regulatory 'maps' based on literary communication

Abstract

Discusses the bibligraphical value of authors' handwritten marginal notes, comments and explanations. Such notes may be merely trivial, or consist of invective, but some examples have proved extremely useful for the comprehension of obscure or contradictory texts. The possibility of surprising discoveries in marginal notes has always attracted some researchers to this field. Cataloguing such notes by fixed rules is difficult; as a bibliographical entity, each note is unique and unrepeatable. Librarians should be flexible and intuitive in their approach. Supports the thesis with historical references and quotations

Abstract

Discusses the 5 new laws of library science formulated by M. Gorman (1995) as an updated reinterpretation of Ranganathan's original rules. Notes Gorman's hostility to outsourcing, his belief that uncontrolled automation in libraries will harm cataloguing, and his view that there will always be a role for printed and other non electronic forms of communication. Reviews also the alternative 'Five new laws of librarianship' proposed by M. Line (1996). Concludes that Ranganathan's 5 precepts remain valid in today's changed conditions

Abstract

Continuing a previous article on CDS/ISIS Micro functions and procedures, illustrates other aspects by recapitulating the strong and weak points of the system. Defects include lack of user firendliness, the search and cataloguing functions, index management, and import/export. Favourable features are total file definition, the formatting language, alphabetical sorting, commands, and data transfer to/from other software environments. ISIS, developed by UNESCO, is a good product, and although demanding for the user, repays the effort made

Abstract

The interfaculty centre of Bologna University began 2 years ago a project to 'translate' UDC codes into a user friendly thesaurus, with the object of creating an accurate, easy to use tool for online researches, especially those relating to periodical titles. The UDC numerical codes have been linked by a method based on synonyms to a series of corresponding verbal indices which express in natural language the concepts expressed by the codes. Thus researchers can retrieve information not only through UDC codes but also through their analogous verbal descriptors. Describes the progress of the UDC project so far, and some problems encountered

Abstract

A detailed examination of the UDC's history, function and future prospects. Among topics discussed are: the early pioneering work of P. Otlet and H. LaFontaine; the development of Colon Classification; the 'UDC versus switching language' debate in the 1970s; the FID standard reference code project; and the recent scheme by Williamson and McIlwaine to restructure UDC completely, converting it into a Colon Classification and also creating a thesaurus drawn from the same classification. Comments that UDC, far from being a 'prehistoric monster', is becoming a sort of test laboratory for developing new and interesting documentation structures

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

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

A crucial question for librarians is whether to catalogue Internet information sources, and electronic sources in general, which may contain metainformation of the texts of articles. Librarians can help researchers with data identification and access in 4 ways: making OPAC available on the Internet; providing a complete selection of Gopher, Ftp, WWW, etc. site lists; maintaining a Web site, coordinateted by the library, that functions as an Internet access point; and organising access to existing search engines that do automatic indexing. Briefly reviews several metadata formats, including USMARC field 856, IAFA templates, SOIP (Harvest), TEI Headers, Capcas Head and URC

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

Discusses the specialised knowledge and training which the multimedia reference librarian needs in order to provide a satisfactory oersonalised assistance service to online and CD-ROM users. Multimedia products combine electronic text, graphic art, animation and video for user interaction from a workstation. Thus the librarian should not only by familiar with search engines and websites, but also understand computer start-up procedures, passwords, keyboards, software and basic maintenance, data security matters and copyright. Explains the 4 distinct levels of librarian help in query-solving

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

Abstract

Library science may well have an essential role to play in efficiently organising the huge amount of Internet information available in the various scientific disciplines. The basic problem is to develop a cataloguing theory sufficiently flexible to cope with the impact of an ever changing store of network data. Such a theory would abondon the utopian idea of a 'catalogue of ctalogues', seeking instead to match each specific user query to the most appropriate catalogue. Examines 2 important USA projects for cataloguing network resources: Digital Libraries Research (funded by the National Science Foundation), which uses a combination of search engines to retrieve net data; and the Internet Public Library.
