- Abstract
- The strongest tradition of IR systems evaluation has focused on system effectiveness; more recently, there has been a growing interest in evaluation of Interactive IR systems, balancing system and user-oriented evaluation criteria. In this paper we shift the focus to considering how IR systems, and particularly digital libraries, can be evaluated to assess (and improve) their fit with users' broader work activities. Taking this focus, we answer a different set of evaluation questions that reveal more about the design of interfaces, user-system interactions and how systems may be deployed in the information working context. The planning and conduct of such evaluation studies share some features with the established methods for conducting IR evaluation studies, but come with a shift in emphasis; for example, a greater range of ethical considerations may be pertinent. We present the PRET A Rapporter framework for structuring user-centred evaluation studies and illustrate its application to three evaluation studies of digital library systems.

- Abstract
- Information-seeking is important for lawyers, who have access to many dedicated electronic resources. However there is considerable scope for improving the design of these resources to better support information-seeking. One way of informing design is to use information-seeking models as theoretical lenses to analyse users' behaviour with existing systems. However many models, including those informed by studying lawyers, analyse information-seeking at a high level of abstraction and are only likely to lead to broad-scoped design insights. We illustrate that one potentially useful (and lower-level) model is Ellis's - by using it as a lens to analyse and make design suggestions based on the information-seeking behaviour of 27 academic lawyers, who were asked to think aloud whilst using electronic legal resources to find information for their work. We identify similar information-seeking behaviours to those originally found by Ellis and his colleagues in scientific domains, along with several that were not identified in previous studies such as 'updating' (which we believe is particularly pertinent to legal information-seeking). We also present a refinement of Ellis's model based on the identification of several levels that the behaviours were found to operate at and the identification of sets of mutually exclusive subtypes of behaviours.

- Abstract
- A user's understanding of the libraries they work in, and hence of what they can do in those libraries, is encapsulated in their "mental models" of those libraries. In this article, we present a focused case study of users' mental models of traditional and digital libraries based on observations and interviews with eight participants. It was found that a poor understanding of access restrictions led to risk-averse behavior, whereas a poor understanding of search algorithms and relevance ranking resulted in trial-and-error behavior. This highlights the importance of rich feedback in helping users to construct useful mental models. Although the use of concrete analogies for digital libraries was not widespread, participants used their knowledge of Internet search engines to infer how searching might work in digital libraries. Indeed, most participants did not clearly distinguish between different kinds of digital resource, viewing the electronic library catalogue, abstracting services, digital libraries, and Internet search engines as variants on a theme.

- Abstract
- This article reports on a longitudinal study of information seeking by undergraduate information management students. It describes how they found and used information, and explores their motivation and decision making. We employed a use-in-context approach where students were observed conducting, and were interviewed about, information-seeking tasks carried out during their academic work. We found that participants were reluctant to engage with a complex range of information sources, preferring to use the Internet. The main driver for progress in information seeking was the immediate demands of their work (e.g., assignments). Students used their growing expertise to justify a conservative information strategy, retaining established strategies as far as possible and completing tasks with minimum information-seeking effort. The time cost of using library material limited the uptake of such resources. New methods for discovering and selecting information were adopted only when immediately relevant to the task at hand, and tasks were generally chosen or interpreted in ways that minimized the need to develop new strategies. Students were driven by the demands of the task to use different types of information resources, but remained reluctant to move beyond keyword searches, even when they proved ineffective. They also lacked confidence in evaluating the relative usefulness of resources. Whereas existing literature on satisficing has focused on stopping conditions, this work has highlighted a richer repertoire of satisficing behaviors.

- Abstract
- Purpose - This research aims to identify some requirements for supporting user interactions with electronic current-awareness alert systems based on data from a professional work environment. Design/methodology/approach - Qualitative data were gathered using contextual inquiry observations with 21 workers at the London office of an international law firm. The analysis uses CASSM ("Concept-based Analysis of Surface and Structural Misfits"), a usability evaluation method structured around identifying mismatches, or "misfits", between user-concepts and concepts represented within a system. Findings - Participants were frequently overwhelmed by e-mail alerts, and a key requirement is to support efficient interaction. Several misfits, which act as barriers to efficient reviewing and follow-on activities, are demonstrated. These relate to a lack of representation of key user-concepts at the interface and/or within the system, including alert items and their properties, source documents, "back-story", primary sources, content categorisations and user collections. Research limitations/implications - Given these misfits, a set of requirements is derived to improve the efficiency with which users can achieve key outcomes with current-awareness information as these occur within a professional work environment. Originality/value - The findings will be of interest to current-awareness providers. The approach is relevant to information interaction researchers interested in deriving design requirements from naturalistic studies.
