Use of multiple digital libraries: a case study

The aim of the work reported here was to better understand the usabili ty issues raised when digital libraries are used in a natural setting. The method used was a protocol analysis of users working on a task of their own choosing to retrieve documents from publicly available digital libraries. Various classes of usability difficulties were found. Here, we focus on use in context - that is, usability concerns that arise from the fact that libraries are accessed in particular ways, under technically and organisationally imposed constraints, and that use of any particular resource is discretionary. The concepts from an Interaction Framework, which provides support for reasoning about patterns of interaction between users and systems, are applied to understand interaction issues.

From physical to digital: a case study of computer scientists' behaviour in physical libraries

There has been substantial research on various aspects of people’s usage of physical libraries but relatively little on their interaction with individual library artefacts; that is: books, journals, and papers. We have studied people’s behaviour when working in physical libraries, focusing particularly on how they interact with these artefacts, how they evaluate them, and how they interact with librarians. This study provides a better understanding of how people interact with paper information, from which we can draw implications for some requirements of the design of digital libraries, while recognising that the term ‘library’ is a metaphor when applied to electronic document collections. In particular, improved communication with other library users and with librarians could facilitate more rapid access to relevant information and support services, and structuring information presentation so that users can make rapid assessments of its relevance would improve the efficiency of many information searches.

Electronic resource discovery systems: from user behaviour to design

Information seeking is a central part of academic development for both students and researchers. However, this is often hindered by complex and highly complicated electronic resource discovery systems. One approach to improving these resources is to understand the difficulties and likely causes of problems when using current systems and how people develop their searching, retrieval and storage strategies. These might provide useful information about the requirements for future design. In this paper we present our findings from UBiRD, a project investigating user search behaviour in electronic resource discovery systems based on a qualitative study of 34 users from three UK universities. We then describe how the information gathered during the study helped inform the design of INVISQUE, a novel non-conventional interface for searching and querying on-line scholarly information. In addition, the theories and design principles used during the INVISQUE design are discussed.
