Abstract

Planning for the next five years of the MELVYL system is described in the context of University of California information system planning. The palnning environment is outlined from which are derived the objectives for the continued growth of the MELVYL system. The technical evolution of the MELVYL system necessary to meet the objectives is also reviewed. Envisioned in this technical evolution is the conversion of the MELVYL system to a client/server architecture that includes a graphical interface. Future plans for the MELVYL system provide a basis for tackling the problems of fragmented databases and information overload. Four initiatives to alleviate these problems are briefly described

Abstract

The first ten years of the MELVYL system have profoundly affected the lives of University of California librarians. The rapid growth of the system's content, complexity, and use has required frequent modifications of its interface. These changes have required the continuous involvement of librarians in advising the system's designers on new features and new databases, in instructing users, and in observing user behavior. This article traces, from a librarian's perspective, the evolution of the system from its origins as a poweful prototype online catalog to its present role as a complex of multiple databases, services, and resources. The article's primary focus is on ways in which the growth, refinement, and development of the system have entailed adaptive design, flexible instruction, and user tolerance for change

Abstract

Librarians find themselves today in a lively period of the evolution of user interfaces to online information. Most of the newer interfaces incorporate graphics, colour and mouse-supported searching to make intiation for the novics user easier and all searching more productive. Describes the University of Delaware's development of DELCAT MacPAC, a HyperCard-based front-end to the university's OPAC, adapted from Cornell University's MacPAC. The focus is on Delaware's customisation of MacPAC for its environment, including the support of remote users, and the testing, use, and distribution of the product

Abstract

Many experts have proposed an evolution toward "next generation catalogs," whose main features are partly inspired by commercial websites such as Google or Amazon. This article examines pros and cons of this integration. It also aims to show how a qualitative approach helps to broaden understanding of web communication mechanisms. After discussing some examples of "next generation catalog" features, I analyze the interface of an online catalog responding to different users' information needs and seeking behaviors. In the conclusion I suggest that the right approach to integration is a "translation" (not a "copy and paste") between commercial and library logics.

Abstract

Paper presented at the 14th biennal conference of IATUL, Cambridge, Mass., USA, 8-12.7.1991: new technologies and information services - evolution or revolution? Ed. by Jay K. Lucker and published by the British Library on behalf of the IATUL. The ETH-Bibliothek is the main library of the Swiss Federal Institute of Technology and the national centre for scientific and technical literature. Mostly there is no open access for the public. The ETHICS project was initiated to run library applications on the the library's own computer. The project is conceived as a multi-library integrated system whose separate units interrelate via a central database. The main function of the system is the online public access catalogue. Describes the specifications of ETHICS including interactive communication in German and French for storing and retrieving data. The subject index is maintained in French, German and English. Discusses retrieval by title words, subject retrieval and alphabetic retrieval. Outlines future developments

Abstract

The construction and updating of indexing languages depend on the organization of their hierarchical structures in order to determine the classification of related terms and, above all, to allow a constant updating of vocabulary, a condition for knowledge evolution. The elaboration of an indexing language for online catalogs of libraries' networks is important considering the diversity and specificity of knowledge areas. From this perspective, the present paper reports on the work of a team of catalogers and researchers engaged in the construction of a hierarchical structure of an indexing language for an online catalog of a university library's network. The work on hierarchical structures began by defining the categories and subcategories that form the indexing language macrostructure by using the parameters of the Library of Congress Subject Headings , the National Library Terminology and the Vocabulary of the University of São Paulo Library's system. Throughout the stages of the elaboration process of the macrostructure, difficulties and improvements were observed and discussed. The results enabled the assessment of the hierarchical structures of the languages used in the organization of the superordinate and subordinate terms, which has contributed to the systematization of operational procedures contained in an indexing language manual for online catalogs of libraries.

Abstract

Will there be a library catalogue in the future and, if so, what will it look like? In the last 25 years, the library catalogue has undergone an evolution, from card catalogues to OPACs, discovery systems and even linked data applications making library bibliographic data accessible on the web. At the same time, users expectations of what catalogues will be able to offer in the way of discovery have never been higher. This groundbreaking edited collection brings together some of the foremost international cataloguing practitioners and thought leaders, including Lorcan Dempsey, Emmanuelle Bermès, Marshall Breeding and Karen Calhoun, to provide an overview of the current state of the art of the library catalogue and look ahead to see what the library catalogue might become. Practical projects and cutting edge concepts are showcased in discussions of linked data and the Semantic Web, user expectations and needs, bibliographic control, the FRBRization of the catalogue, innovations in search and retrieval, next-generation discovery products and mobile catalogues.

Abstract

Subject searching is the most common but also the most conflictive searching for end user. The aim of this paper is to check how users expressions match subject headings and to prove if knowledge structure used in online catalogs enhances searching effectiveness. A bibliographic revision about difficulties in subject access and proposed methods to improve it is also presented. For the empirical analysis, transaction logs from two university libraries, online catalogs (CISNE and FAMA) were collected. Results show that more than a quarter of user queries are effective due to an alphabetical subject index approach and browsing through hypertextual links. 1. Introduction Since the 1980's, online public access catalogs (OPAC's) have become usual way to access bibliographic information. During the last two decades the technological development has helped to extend their use, making feasible the access for a whole of users that is getting more and more extensive and heterogeneous, and also to incorporate information resources in electronic formats and to interconnect systems. However, technology seems to have developed faster than our knowledge about the tasks where it has been applied and than the evolution of our capacities for adapting to it. The conceptual model of OPAC has been hardly modified recently, and for interacting with them, users still need to combine the same skills and basic knowledge than at the beginning of its introduction (Borgman, 1986, 2000): a) conceptual knowledge to translate the information need into an appropriate query because of a well-designed mental model of the system, b) semantic and syntactic knowledge to be able to implement that query (access fields, searching type, Boolean logic, etc.) and c) basic technical skills in computing. At present many users have the essential technical skills to make use, with more or less expertise, of a computer. This number is substantially reduced when it is referred to the conceptual, semantic and syntactic knowledge that is necessary to achieve a moderately satisfactory search. An added difficulty arises in subject searching, as users should concrete their unknown information needs in terms that the information retrieval system can understand. Many researches have focused an unskilled searchers' difficulties to enter an effective query. The mental models influence, users assumption about characteristics, structure, contents and operation of the system they interact with have been analysed (Dillon, 2000; Dimitroff, 2000). Another issue that implies difficulties is vocabulary: how to find the right terms to implement a query and to modify it as the case may be. Terminology and expressions characteristics used in searching (Bates, 1993), the match between user terms and the subject headings from the catalog (Carlyle, 1989; Drabensttot, 1996; Drabensttot & Vizine-Goetz, 1994), the incidence of spelling errors (Drabensttot and Weller, 1996; Ferl and Millsap, 1996; Walker and Jones, 1987), users problems
