A library or just another information resource? A case study of users' mental models of traditional and digital libraries

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

Required Reading for Library Administrators Part 1

The library and information science literature is overflowing with how-to articles, particularly how to manage the library. Increasingly, library managers find that the time they have available to peruse such literature lessens as other professional demands intrude. With this trend in mind, members of the Comparative Library Organization Committee (CLOC), a LAMA/LOMS standing committee, decided that a list of required readings is in order. Not just another bibliography, the selection of titles was developed using citation analysis, or bibliometrics, to select highly cited authors and titles for works published outside of the professional library literature, and for works published within that literature.(FN1) Members of CLOC then annotated the top twenty titles in each of the two categories from the critical perspective of professional practice. Part one of this work, published in Library Administration and Management (volume 16, number 3, summer 2002), contained the twenty most highly cited works published outside the library profession. This second part contains the twenty most highly cited works published in the library literature. Part one includes an extensive description of how the lists were compiled and will not be repeated here

Studying Academic Lawyers' Information-Seeking to Inform the Design of Digital Law Libraries

We report findings from the initial phase of our study on legal information seeking, which comprised a series of semi-structured interviews and naturalistic observations of academic law students and staff looking for electronic legal information. This study has the long-term aim of informing the design of digital law libraries. Participants found it difficult to use digital law libraries, arising from poor knowledge of the digital library system rather than from poor general electronic research skills. Hazy and faulty system-related knowledge were rife, suggesting the need for academic lawyers to understand more about the digital library systems that they use (within-systems knowledge). These lawyers chose to rely primarily on one major digital law library for legal information seeking. Their preference was often based upon vague or flawed rationale and suggests the need for academic lawyers to appreciate the situations in which different electronic resources might be useful (between-systems knowledge)

Studying Lawyers’ Information Seeking Behaviour to Inform the Design of Digital Law Libraries

In this paper, we describe our ongoing work which involves examining the information seeking behaviour of legal professionals. This work involves studying the behaviour of both academic and practicing lawyers with the long-term aim of integrating user-centred legal information seeking support into digital law libraries. We report preliminary findings from the initial phase of the study, which comprised a series of semistructured interviews and naturalistic observations of academic law students looking for information that they require for their work. This group of academic lawyers often found it difficult to find the information that they were looking for when using digital law libraries. A potential symptom of this difficulty was that hazy and incorrect knowledge of the digital library system and information sources within the system were rife. This suggests the need for students to understand more about the digital library systems that they use (within-systems knowledge). We also found that although this group of academic lawyers often used several electronic resources in a complementary fashion to conduct legal information seeking, they often chose to rely primarily on one of either the LexisNexis or Westlaw digital law library platforms. Their preference was often based upon vague or sometimes flawed rationale and suggests the need for students to appreciate the situations in which different electronic resources might be useful (between-systems knowledge)

On Birthing Dancing Stars: The Need for Bounded Chaos in Information Interaction

While computers causing chaos is acommon social trope, nearly the entirety of the history of computing is dedicated to generating order. Typical interactive information retrieval tasks ask computers to support the traversal and exploration of large, complex information spaces. The implicit assumption is that they are to support users in simplifying the complexity (i.e. in creating order from chaos). But for some types of task, particularly those that involve the creative application or synthesis of knowledge or the creation of new knowledge, this assumption may be incorrect. It is increasingly evident that perfect order—and the systems we create with it—support highly-structured information tasks well, but provide poor support for less-structured tasks.We need digital information environments that help create a little more chaos from order to spark creative thinking and knowledge creation. This paper argues for the need for information systems that offerwhat we term ‘bounded chaos’, and offers research directions that may support the creation of such interface

This is what I'm doing and why: reflections on a think-aloud study of digital library users' information behaviour

Many user-centred studies of digital libraries include a think-aloud element – where users are asked to verbalise their thoughts, interface actions and sometimes their feelings whilst using digital libraries to help them complete one or more information tasks. These studies are usually conducted with the purpose of identifying usability issues related to the system(s) used or understanding aspects of users‟ information behaviour. However, few of these studies present detailed accounts of how their think-aloud data was collected and analysed or provide detailed reflection on their methodologies. In this paper, we discuss and reflect on the decisions made when planning and conducting a think-aloud study of lawyers‟ interactive information behaviour. Our discussion is framed by Blandford et al.‟s PRET A Rapporter („ready to report‟) framework – a framework that can be used to plan, conduct and describe user-centred studies of digital library use from an information work perspective

Teaching and learning in information retrieval

A literature review of pedagogical methods for teaching and learning information retrieval is presented. From the analysis of the literature a taxonomy was built and it is used to structure the paper. Information Retrieval (IR) is presented from different points of view: technical levels, educational goals, teaching and learning methods, assessment and curricula. The review is organized around two levels of abstraction which form a taxonomy that deals with the different aspects of pedagogy as applied to information retrieval. The first level looks at the technical level of delivering information retrieval concepts, and at the educational goals as articulated by the two main subject domains where IR is delivered: computer science (CS) and library and information science (LIS). The second level focuses on pedagogical issues, such as teaching and learning methods, delivery modes (classroom, online or e-learning), use of IR systems for teaching, assessment and feedback, and curricula design. The survey, and its bibliography, provides an overview of the pedagogical research carried out in the field of IR. It also provides a guide for educators on approaches that can be applied to improving the student learning experiences

Investigating users’ mental models of traditional and digital libraries

There is much HCI-related literature on mental models and on the usability of digital libraries, however there is no previously published literature on users’ mental models of either traditional or digital libraries. This is surprising, since many digital libraries are difficult to use and it is not immediately clear why. Our study begins to fill this void by examining users’ mental models of traditional and digital libraries through a series of Contextual Inquiry interviews that mix traditional think-aloud observations, which usually demand minimal researcher intervention, and semi-structured interviews, which usually demand significant intervention. The study finds that participants’ mental models of traditional and digital libraries extend beyond surface similarities and differences, such as the hierarchical organisation of items in both types of library and the availability of documents in paper and electronic mediums. These models contain deeper similarities and differences based on the information-seeking goals that can be fulfilled by each type of library, issues concerning the contents and relevance of individual documents and entire libraries, and ‘how searching works’ and how to ‘troubleshoot’ in both types of library. Although the use of concrete analogies to influence users’ understanding or usage of digital libraries was not widespread, participants used their knowledge of Internet search engines to infer how searching might work in digital libraries. Additionally, most participants assumed that even if different at the interface level or at the level of the underlying technology employed, the search components of digital libraries, Internet search engines and other digital entities work in a similar way to bring back search results. The study also finds that a large component of users’ mental models of digital libraries is the notion of access restrictions. The insights gained from the observations relating to the above recurring themes in users’ mental models are discussed with a view of helping to improve digital library usability by reducing access restrictions and notifying users of any such restrictions upfront, by providing dynamic and context-dependent help to users, by carefully introducing analogies into the digital library interface (if and where appropriate) and by making multiple digital libraries searchable under a single front-end to enable them to be accessed, browsed and searched in the same way

Digital libraries and the future of the library profession

To argue that unique contemporary cultural shifts are leading to a new form of librarianship that can be characterised as "postmodern" in nature, and that this form of professional specialism will be increasingly influential in the decades to come
