    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
    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
    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
    Considers the 2 conflicting phenomena of disintermediation and information overload, which in the Internet era respectively pose a threat and offer an opportunity to the librarian and information science profession. User-orientated commercial products and services are tending to promote user information autonomy; but, more positively, the online electronic publication explosion has impelled librarians to cretae Net information resource catalogues, and the IT community to devise novel Internet access tools. Librarians will thus have a useful role to fulfil in both the free and fee-paying E-information sectors as cybrarians or information managers

    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. Lists the Management and Library Schools now on the WWW

    Abstract
    Illustrates how a public library reference service that aims to utilise all types of information resources, both traditional and electronic, increases the options available to users but at the same time risks the emergence of 'Chaotic' situations, arising from inadequate training of the librarian; damage to or misuse of equipment by users; breaches of copyright; or the unforeseen hidden costs involved in Internet based resources. Discusses the 2 levels of training needed by electronic reference librarians; the essential knowledge they require; the pros and cons of reference service fee charging; and the problem of finding the right balance between CD-ROM and Internet resources

    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
    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
    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

    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. Provides statistics on time spent in research

    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
    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

    The guide Nuovo soggettario was presented on February 8' 2007 at a one-day seminar in the Palazzo Vecchio, Florence, in front of some 500 spellbound people. The Nuovo soggettario comes in two parts: the guide in book-form and an accompanying CD-ROM, by way of which a prototype of the thesaurus may be accessed on the Internet. In the former, rules are stated; the latter contains a pdf version of the guide and the first installment of the controlled vocabulary, which is to be further enriched and refined. Syntactic instructions (general application guidelines, as well as special annotations of particular terms) and the compiled subject strings file have yet to be added. The essentials of the new system are: 1) an analytic-synthetic approach, 2) use of terms (units of controlled vocabulary) and subject strings (which represent subjects by combining terms in linear order to form syntactic relationships), instead of main headings and subdivisions, 3) specificity of terms and strings, with a view to the co-extension of subject string and subject matter and 4) a clear distinction between semantic and syntactic relationships, with full control of them both. Basic features of the vocabulary include the uniformity and univocality of terms and thesaural management of a priori (semantic) relationships. Starting from its definition, each term can be categorially analyzed: four macro-categories are represented (agents, action, things, time), for which there are subcategories called facets (e.g., for actions: activities, disciplines, processes), which in turn have sub-facets. Morphological instructions conform to national and international standards, including BS 8723, ANSI/ NISO Z39.19 and the IFLA draft of Guidelines for multilingual thesauri, even for syntactic factorization. Different kinds of semantic relationships are represented thoroughly, and particular attention is paid to poly-hierarchies, which are used only in moderation: both top terms must actually be relevant. Node labels are used to specify the principle of division applied. Instance relationships are also used.
    Thesaurus software is based on AgroVoc (http:// www.fao.org/aims/ag_intro.htm) provided by the FAO, but in modified form. Many searching options and contextualization within the full hierarchies are possible, so that the choice of morphology and syntax of terms and strings is made easier by the complete overview of semantic relationships. New controlled terms will be available soon, thanks to the work in progress - there are now 13,000 terms, of which 40 percent are non-preferred. In three months, free Internet access by CD-ROM will cease and a subscription will be needed. The digital version of old Soggettario and the corresponding unstructured lists of headings adopted in 1956-1985 are accessible together with the thesaurus, so that the whole vocabulary, old and new, will be at the fingertips of the indexer, who is forced to work with both tools during this transition period. In the future, it will be possible to integrate the thesaurus into library OPACs. The two parts form a very consistent and detailed resource. The guide is filled with examples; the accurate, clearly-expressed and consistent instructions are further enhanced by good use of fonts and type size, facilitating reading. The thesaurus is simple and quick to use, very rich, albeit only a prototype; see, for instance, a list of DDC numbers and related terms with their category and facet, and then entries, hierarchies and so on, and the capacity of the structure to show organized knowledge. The excellent outcome of a demanding experimentation, the intended guide welcomes in a new era of subject indexing in Italy and is highly recommended. The new method has been designed to be easily teachable to new and experimented indexers.
