This poster proposal describes research on humanities users of a digital library (DL). It seeks to understand their needs and behaviour both in digital and more traditional information environments, in order to develop and refine a digital library system, the better to support use in the humanities. This study of humanities users forms part of the larger
Large, structured information repositories such as digital libraries (DLs) are becoming commonplace. To realise their potential, they need to be usable and useful - by a range of users, in different situations, supporting a variety of information tasks. The current generation of DLs still poses substantial user difficulties: searches are often time-consuming and frequently unsuccessful (Blandford et al.), and the reasons for success or failure remain mysterious to most users. Within the broader information task, the information requirements are often poorly defined, as users are often trying to refine the information problem by using available information to understand what is possible, so that information acquisition is an evolving, highly interactive activity.
It is widely recognised that creating effective search criteria to achieve a particular information goal is a demanding and difficult task, particularly for less experienced users, and particularly when the goal is as yet under-defined. Shneiderman et al. observe the challenges of selecting a variety of search attributes, such as the words to be used in a query and the syntactic peculiarities of the system at hand. In addition, the mapping of an information need to the use of metadata fields or full text search can prove difficult (Blandford et al.). Unlike the web, where the document text is the only possible target for a search, DLs provide a rich environment for information seeking: the user has a much wider potential range of selections (classification, author, publication date, etc.) to make. Effective searching relies on the careful selection and use not only of words or syntactic commands, but also of fields and information sources.
Surprisingly little work on information seeking has set it within the context of the broader information work of which it is a component (Attfield et al.). While this divorce from the context may be valid when considering work in physical libraries, where the information seeking task is often a bounded activity delineated by arrival at and departure from the library building, it is less so for DLs that can be accessed from the user's normal place of work, removing the marked transitions between information seeking and other activities. One hypothesis this study will test is that users expect information seeking to flow more naturally into their broader information task when searching from their normal place of work.
Humanities researchers are the focus for studying use in context for several reasons: they typically have little technical or mathematical knowledge (e.g. for immediately understanding the designs of complex interactive systems or intuitively being able to construct the Boolean queries that are often key to successful query formulation); they often do not have a clear idea of what they are looking for, but will usually recognise it when they find it; and they have not been extensively studied, although they have substantial and sophisticated information requirements. In summary, humanities researchers are a particularly challenging population to design for, and many solutions that work for this user population are likely to also suit less demanding users. Studies of humanities researchers have tended to concentrate on needs or the types of resources used (
Warwick's previous work suggests that humanities users may find it difficult to adapt search behaviour from a traditional to a digital library setting, and thus become discouraged by failed attempts to locate appropriate resources (Warwick, 1999a; 1999b) She has found that the patterns of use of digital resources in English literature have changed little since Corns' work in 1991, and argued that this may be because of lack of fit between the searching tasks users wish to carry out and the present capabilities of DLs. This was based on only a small sample of users, and on theoretical data. It is therefore important to test these hypotheses by studying a meaningful sample of humanities users in both a traditional library setting and a digital environment. This is one of the tasks that the present research is engaged in.
Overall, there are four strands of work in the UCIS project:
The proposed poster will describe the first strand of work, briefly outlining how it fits within the rest of the project. We believe that this work is important since very little work has studied use in context - particularly in the humanities - and translated findings into testable design requirements.
Qualitative data (from interviews, observations, diary studies, transaction logs, etc.) will be gathered from academics and other researchers in the humanities regarding their activities with DLs and similar information resources. Two sub-issues will direct this work: how humanities researchers work with digital resources and how they integrate use of electronic and paper resources - both within the broader task context.
The first approach to data collection will be by user diaries, in which humanities users record their use of information resources (both traditional and digital) to support their research. This will provide base-line data to inform the use of techniques for subsequent study (depending on the patterns of resource use). The main approach to data collection will be contextual inquiry interviews, observing users as they work with digital libraries of their own choice and interviewing them on their perceptions of the usability of such electronic information sources. The focus of this data collection will cover what users currently do, their perceptions of the strengths and limitations of current technologies (including traditional resources), and requirements for future systems.
Data will be analysed in two different but complementary ways: first, using a Grounded Theory-style approach (Strauss and Corbin) to develop theory on the use of digital resources in context by humanities users; second, using design-oriented techniques to draw out requirements for design.
To enable us to focus on new technical challenges rather than needing to replicate work already done by others, technical developments will be based on the
