Perceptions of Usability and Usefulness in Digital Libraries

This paper provides an overview of a case study research that investigated the use of Digital Library (DL) resources in two undergraduate classes and explored faculty and students’ perceptions of educational digital libraries. This study found that students and faculty use academic DLs primarily for textual resources, but turn to the open Web for visual and multimedia resources. The study participants did not perceive academic libraries as a useful source of digital images and used search engines when searching for visual resources. The limited use of digital library resources for teaching and learning is associated with perceptions of usefulness and ease of use, especially if considered in a broader information landscape, in conjunction with other library information systems, and in the context of Web resources. The limited use of digital libraries is related to the following perceptions: 1) Library systems are not viewed as user-friendly, which in turn discourages potential users from trying DLs provided by academic libraries; 2) Academic libraries are perceived as places of primarily textual resources; perceptions of usefulness, especially in regard to relevance of content, coverage, and currency, seem to have a negative effect on user intention to use DLs, especially when searching for visual materials

Students’ perceptions toward the usability and usefulness of the digital libraries: A Case Study of Women University in District Peshawar.

This paper investigated the perceptions of undergraduate students regarding usability and usefulness of Digital Libraries. A case study was conducted to explore the use of Digital Library (DL) resources in ten undergraduate classes at Shaheed Benazir Butto Women University Peshawar and identified students\u27 perceptions regarding educational digital libraries. Data was collected through survey method using qualitative tools such as observation and interviews. The study examined that university provides internet facility to all students and they have ample access for using Digital libraries but majority of the students are not aware of the use of DLs. Only research students are using digital libraries and most of them use it for research purpose while other using open Web sources for visual and multimedia purpose. Furthermore students did not recognize academic libraries as a useful source for digital images and used various search browsers while searching for visual resources. Students stated that the digital library websites are difficult to navigate and insufficient in providing signs about the richness of resources that it offers. Students’ experiences regarding the use of library website badly affected their perceptions about digital services

What is usability in the context of the digital library and how can it be measured?

This paper reviews how usability has been defined in the context of the digital library, what methods have been applied and their applicability, and proposes an evaluation model and a suite of instruments for evaluating usability for academic digital libraries. The model examines effectiveness, efficiency, satisfaction, and learnability. It is found that there exists an interlocking relationship among effectiveness, efficiency, and satisfaction. It also examines how learnability interacts with these three attributes

Users' trust in information resources in the Web environment: a status report

This study has three aims; to provide an overview of the ways in which trust is either assessed or asserted in relation to the use and provision of resources in the Web environment for research and learning; to assess what solutions might be worth further investigation and whether establishing ways to assert trust in academic information resources could assist the development of information literacy; to help increase understanding of how perceptions of trust influence the behaviour of information users

A usability study of online library systems: A case of Sultanah Bahiyah Library, Universiti Utara Malaysia

The purpose of this study was to investigate usability of online library systems in Universiti Utara Malaysia (UUM). This study evaluated the usability of Sultanah Bahiyah Library’s web based systems by investigating the aspects of simplicity, comfort, user friendliness, control, readability, information adequacy/task match, navigability, recognition, access time, relevancy, consistency and visual presentation. This study examined user’s views about the usability of digital libraries whereas current and perceived importance. A sample of 45 students of Master of Business Administration (MBA) has been chosen. The Sultanah Bahiyah Library’s web based systems is very important especially for students and academic staffs of Universiti Utara Malaysia. The usability of the Library’s web based systems makes students easy to connect and for that the website should be helpful and attractive within good contents. The result found that the parallel nature of the users’ current views about the usability of digital libraries and users’ perceived importance of digital library usability allows direct comparison of all usability properties. The overall results yielded significant difference for the variables of user’s current views and perceived importance

The onus on us? Stage one in developing an i-Trust model for our users.

This article describes a Joint Information Systems Committee (JISC)-funded project, conducted by a cross-disciplinary team, examining trust in information resources in the web environment employing a literature review and online Delphi study with follow-up community consultation. The project aimed to try to explain how users assess or assert trust in their use of resources in the web environment; to examine how perceptions of trust influence the behavior of information users; and to consider whether ways of asserting trust in information resources could assist the development of information literacy. A trust model was developed from the analysis of the literature and discussed in the consultation. Elements comprising the i-Trust model include external factors, internal factors and user's cognitive state. This article gives a brief overview of the JISC funded project which has now produced the i-Trust model (Pickard et. al. 2010) and focuses on issues of particular relevance for information providers and practitioners

Bridge Over Troubled Water: QR coding the collection for student satisfaction

Since 2012, BU (Bournemouth University) library have been highlighting available, relevant e-books by embedding QR codes in our printed book collection. This chapter will focus on the drivers and intended outcomes for the project and will discuss the characteristics of successful QR campaigns that we have considered to achieve our aims. A more practical discussion of project implementation is in press at the time of writing (Ford, 2013)

Evaluating the usability and usefulness of a digital library

Purpose - System usability and system usefulness are interdependent properties of system interaction, which in combination, determine system satisfaction and usage. Often approached separately, or in the case of digital libraries, often focused upon usability, there is emerging consensus among the research community for their unified treatment and research attention. However, a key challenge is to identify, both respectively and relatively, what to measure and how, compounded by concerns regarding common understanding of usability measures, and associated calls for more valid and complete measures within integrated and comprehensive models. The purpose of this paper is to address this challenge. Design/methodology/approach - Identified key usability and usefulness attributes and associated measures, compiled an integrated measurement framework, identified a suitable methodological approach for application of the framework, and conducted a pilot study on an interactive search system developed by a Health Service as part of their e-library service. Findings - Effectiveness, efficiency, aesthetic appearance, terminology, navigation, and learnability are key attributes of system usability; and relevance, reliability, and currency key attributes of system usefulness. There are shared aspects to several of these attributes, but each is also sufficiently unique to preserve its respective validity. They can be combined as part of a multi-method approach to system evaluation. Research limitations/implications - Pilot study has demonstrated that usability and usefulness can be readily combined, and that questionnaire and observation are valid multi-method approaches, but further research is called for under a variety of conditions, with further combinations of methods, and larger samples. Originality/value - This paper provides an integrated measurement framework, derived from the goal, question, metric paradigm, which provides a relatively comprehensive and representative set of system usability and system usefulness attributes and associated measures, which could be adapted and further refined on a case-by-case basis
