Abstract

We have recently completed a survey of the operational use of hypertext-based information systems in academic, public and special libraries in the UK. A literatur search, questionnaire and both telephone and face-to-face interviews demonstrate that the principle application of hypertext systems is for the implementation of public-access point-of-information systems, which provide guidance to the users of local information resources. In this paper, we describe the principle issuse relating to the design and usage of these systems that were raised in the interviews and that we experienced when using the systems for ourselves. We then present a set of technical recommendations with the intention of helping the developers of future systems, with special attention being given to the need to develop effective methods for system evaluation

Abstract

Describes the creation and results of a questionnaire survey of cataloguers in 6 Singapore academic and national libraries and of their vendor helpdesk staff to evaluate the help systems of library automation systems, with particular emphasis on the cataloguing function. Describes the structure of the questionnaire; the methodology used to analyse the data; the profile of the respondents and the systems used by them; and the implications of the statistical results. Functionalities for the following help features were surveyed: getting in and out of the help systems; selecting a relevant topic; formulating queries; searching of information; completeness and comprehensiveness of the help system; navigation to other topics; applying information to solve problems; and data entry and authority control in cataloguing tasks. Data analysis identified 27 preferred features which could be taken into account in the product development of online help systems

Abstract

The relevance of retrieved documents or document descriptions has been a central measurement in the evaluation of information retrieval (IR) systems. Online public access catalogues (OPACs) are similar in many ways and so relevance should be an appropriate evaluation tool in measuring their performance. The development of relevance in evaluating IR systems is described and also the important differences between such systems and OPACs. Characteristics of the end-users of both systems are discussed with the conclusion that end-users' motivation and behaviour are as yet not fully understood. The implcations of this is that relevance is a central feature, but only one, of an OPAC user's overall information need

Abstract

This article discusses the provision of "help" in interactive information retrieval system (IIRS) and describes a comparative survey of the "help" facilities of 16 such systems. Six guidelines for the design of a "help" facility are drawn up and these are used to evaluate the quality and friendliness of the "help" provided by each system. The scores indicate that "help" on IIRS is often inadequate, especially on the commercial online systems. This article concludes by discussing why "help" is so unfriendly and by suggesting some ways in which online "help" could be improved

Abstract

In this article I will look at the changig computing resources required to run a large information retrieval system like the MELVYL system. I will give a historical perspective, examining the aerly days of the MELVYL system and how the system has changed in the last decade. I will also provide some perspective on how new technologies have affected large information retrieval systems and what technologies will be required of such systems in the future, as the demands and requirements of large information retrieval systems continue to mature to meet increasing user needs.

Abstract

Rare book cataloguers have on various occasions expressed frustration that their carefully constructed rare book records 'disappear' into 'vanilla' catalogues designed and maintained by system vendors or by local system staff with only the most general knowledge of cataloguing. Reports the results of a 1993 survey of online systems used for rare book cataloguing and takes a first step toward making a set of recommendations regarding the display and indexing of rare book records in such systems

Abstract

Study was undertaken by Information Systems Consultants, Inc., Washington DC, to determine the current state of online patron access catalogues, with emphasis on the degree to which access has been extended beyond that available in card, microform, and early patron access online catalogues. The methodology used was similar to that used in an earlier report. All of the library automation vendors of both multi user systems and micro based systems were sent a copy of the latest version of the catalogue portion of the model RFP (request for proposal) for an integrated online library system which was developed for the study described in the last reference. The vendors were asked to respond as if it had been sent by a potential library customer. A matrix with the raw data is presented for both multi user systems and micro based systems along with the RFP. A brief description of each vendor is followed by a tabulation of the RFP responses and concluding comments by the author

Abstract

Reports results of a questionnaire survey of the user characteristics of Korean student user groups in searching OPACs. The study examined the use of 5 selected OPAC systems in 5 academic libraries in the Austin, Texas and North Texas areas. The objective was to provide information on the characteristics of a specific group of international college students from a developing country in order to assist system managers in the selection of OPAC systems. The major conclusions of this study were: the academic level and age of students affect the preference towards an OPAC, but academic major of the students does not affect the preference; system designers should prepare more specific instructions regarding searching methods; there is a negative relationship between the number of searching methods that the respondents knew in using OPACs and the frequency of manual card catalogue use; and menu driven systems should be the first selection of OPAC systems for Korean students. Proposes recommendations for the design, adoption, or management of a new OPAC system
