Abstract

Purpose - The purpose of this paper is to review the nature of, and rationale for, user expectations in the digital library setting, and ways in which they may best be met and/or managed. Design/methodology/approach - An analysis of the literature, focusing on empirical studies, and bringing out main themes and issues. Findings - User expectations of digital libraries are often unrealistic, usually unrealistically high, mainly due to the ubiquity of the web search engine as an information environment. Expectations differ between user groups. Both meeting and managing expectations have been promoted as a solution; it is likely that a mix of the two will be most effective. More empirical and conceptual studies are needed. Ways of making the nature of digital library collections and their organisation "visible", embedded in a natural way within their interfaces, are desirable. Originality/value - This is the first paper to review the literature of this topic.

Abstract

This presentation gives an international comparison of performance measures of the public and national library services of Lithuania, Slovenia and the United Kingdom. Particular attention will be given to new methods of assessing the value of libraries, which go beyond simple counts of readers and transactions. The importance of treating performance measures as a part of strategic planning, rather than as an aim in itself, is emphasised.

Abstract

Purpose - Aims to present a comparison and evaluation of four user interfaces of web-based e-journals (Science Direct, ProQuest Direct, EBSCO Host and Emerald). Design/methodology/approach - The systems were assessed in an expert study according to accepted guidelines regarding user friendliness and functionality. User friendliness features studied were: language(s) and type(s) of interface; navigation options; personalization; and screen features. Functions inspected were: database selection; query formulation and reformulation; results manipulation; and help. Findings - Many similarities were found, but some differences among the systems were also discovered and analysed in detail. The greatest differences were found in the area of query formulation, and between the interface languages and types. Research limitations/implications - The user interfaces of four full-text IR systems offering e-journals which are accessible at the University of Ljubljana are surveyed. Practical implications - The interfaces are surveyed and assessed in order to discover their characteristics, advantages, and potential downsides and/or mistakes which may hinder use by an average user. Originality/value - The study serves as a basis for a subsequent user study of the information behaviour of the users of these systems.

Abstract

This article presents one part of a wider study, performed at the Department of library and information science and book studies (LIS & BS) at the University of Ljubljana (UL). The study investigated the perceptions of user friendliness of information-retrieval systems (IRS) and the role of individual characteristics of users in these perceptions. Based on an expert study, a user study with 61 postgraduate students of the UL was performed. Three interfaces of e-journals were studied: Science Direct, Proquest Direct, and Ebsco Host. Questionnaires and observations were used for data collection. The users'perceptions of user friendliness and of importance of auxiliary functions were investigated. Also, the connections between these perceptions and the users'individual characteristics were identified. Three sets of individual characteristics were included: approaches to studying, thinking styles, and hemisphere leanings. In connection with the dimensions of individual characteristics, very different perceptions of user friendliness were expressed. Some dimensions of individual characteristics were also found to be connected to the users'academic areas. It is shown that participants from different academic areas have different requirements and perceptions of user friendliness. The results of the study are relevant for the design of the user interfaces of disciplinary IR systems. They also have implications for other areas, for example, user education and training.
