Abstract
This paper attempted to develop and validate an instrument that measures users' views about the usability of digital libraries. Users' views toward the usability of digital libraries may serve as the major conduit to user acceptance and satisfaction, thus promoting positive learning experiences. The instrument, digital library usability, consisted of 12 items that described usability properties of digital libraries. The content validity of the instrument was determined by a panel of experts. The instrument was administered to 293 subjects. The construct validity was determined by conducting a set of statistical procedures, including a principal component analysis. The results revealed a single component solution that assessed one particular trait. All items of the instrument achieved high loading values indicating that each item contributed to the assessment of the single component that accounted for a high variation among the items. The internal consistency (Cronbach alpha) was .96. These results suggest that the digital library usability instrument is a valid and reliable instrument that can measure users' views about the usability of digital libraries. This instrument can be the basis for future research regarding users' views toward the usability of digital libraries.

Perceptions of usability and usefulness of digital libraries
International Journal of Humanities and Arts Computing , 2012
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.
Usability Assessment of Web Digital Library: A Survey Among Undergraduate Students
Recognizing the significance of the usage construct as one of the aspect of usability assessment of the digital library (DL), this study further extends past studies by integrating this construct into commonly used criteria, namely, satisfaction, learnability, effectiveness, and efficiency. Building upon these constructs, an interrelationship model was developed and tested empirically using a survey research methodology. The learnability, effectiveness, and efficiency construct were hypothesized as significant predictors of usage and satisfaction. In addition, the usage construct was also hypothesized as a significant predictor of satisfaction. Data were collected from 320 undergraduate students from the Faculty of Information Management (FIM), Universiti Teknologi MARA (UiTM) Puncak Perdana. The results of the Structural Equation Modeling (SEM) analysis showed all postulated hypotheses were fully supported. The contribution of the study can be assessed from the theoretical and practical perspectives. The established model can be further validated in other DL implementation while the validated instrument can be used by practitioner to gauge the usability of the DL.

The Importance of Usability in Development of Digital Libraries
2000
Digital libraries are among the most interesting electronic information resources of our time. They are the collection of services and the collection of information objects and services that support users in accessing information objects available on the Internet. They are complex information systems consisting of many components which depend on each other in their operation. To achieve the flawless operation of digital libraries their developers should evaluate their achievements during the phase of development as well as during the phase of use. As a result of their efforts, users should get usable and easy to use information systems which are adapted to their needs and preferences. Evaluation and usability are two important concepts which may help librarians and computer specialists to design better information systems and better services for them. Usability testing may include one (usually the user interface) or many components of an information system for evaluation. Evaluation also includes the research of user community. Information acquired in such a way may also significantly help in information system improvement. Since the goal of evaluation is to achieve quality and improvement, the final result should be a superior information system like digital library and satisfied users.

User Acceptance of Digital Library: An Empirical Exploration of Individual and System Components
2005
Potential users of digital libraries may not use the systems in spite of digitization efforts being popular. There is a need to understand the users’ perspective and their acceptance of digital libraries. We use the technology acceptance model as a theoretical basis to understand individual acceptance of users. In this study, five individual and system components are used to explore individual user acceptance of a digital library. We find that antecedents such as search function, screen design, navigation and system reliability have significant effects on perceived ease-of-use and perceived usefulness which in turn have a significant effect on individual user acceptance.
An Assessment of the Usability of the Africa University Digital Library, Mutare, Zimbabwe
International Journal of Emerging Trends & Technology in Computer Science (IJETTCS), 2014
As numbers of digital library users increase, issues pertaining to interaction with the interface and utility of its collection also arise. In responds to the above, this study sought to facilitate the development of user centered digital libraries through user participation and involvement. An evaluation research design was used for the accomplishment of the research objectives. The research population consisted of 30 undergraduate students, 18 graduate students, 12 academic staff and 2 electronic resources staff. Questionnaires, interviews, and indirect observations were used to collect data. The results obtained led to conclusions that there was general dissatisfaction of users regarding the usability evaluation of the Africa University digital library, especially in terms of the adequacy of the collection and the system responds time. Bandwidth problems, lack of user training, and lack of cooperation from faculty librarians were noted as the main inhibitors to the attainment of the highest degree of usability for the digital library in terms of satisfying user needs and expectations. Recommendations were thus given for the digital library development team to involve user views and Faculty Librarians together with the Information and Communication Technology staff in the digital library development process.

Looking at Library Usability: Matching the Concept from User's Experiences 1
2012
This study examined user's current experiences about the usability of the libraries. Their views about the usability of the libraries may play an important role in the success of learning in general. Thus, this paper focuses on current views that reveal what users believe about the usability of existing libraries services and facilities offered. Historically, the quality of the library services have been described in terms of its collection and measured by the size of the library's holding and various counts of its use. This traditional orientation no longer offers attainable goals for addressing successfully the community's demands for information. Identifying new ways to conceive of quality and to monitor its attainment are current challenges for us as an academic library. While the business world has made great strides in focusing on customer service by studying customers' needs and behaviors, libraries have tended to structure their holdings and services around what they believed was good for their customers or users. A syndrome named "librarians know best" required the librarians to transform the institution to a userfocused library. We are doing a survey by asking our users what they need and by listening carefully to what they say. Also continuously, monitoring what we are doing and asking what we could be doing better. The most important change we are making in our behavior is to evaluate our activities through our user's eyes and ask ourselves what effect our actions will have on customer service and satisfaction.

A Usability Evaluation Methodology of Digital Library
2015
Digital Libraries are information systems that allow managing and preserving digital resources, as well as providing access to them. The designing of these kinds of systems should always be completed having in mind the users. Accordingly, it is of outmost importance that the user interface presents a high level of usability. In this paper, a usability evaluation methodology of Digital Libraries is proposed; specifically for the Web site of Academic Digital Libraries. The methodology offers a evaluation instrument that collects the users' perceptions through four dimensions (effectiveness, efficiency, satisfaction and learnability). In addition, the gap theory of quality service is employed and a fuzzy linguistic approach using aggregation operators, which operate directly with words (linguistic information) is applied. Therefore, the methodology shows to be a significant, innovative contribution to the research area on usability evaluation of digital libraries. It can be useful ...
Finding Problems: When Digital Library Users Act as Usability Evaluators
Users in digital library usability evaluation typically participate as subjects in studies designed and conducted by usability experts and digital library researchers. What happens however when users take the role of the researchers, and with some basic HCI training, design and conduct their own evaluation of a digital library? For several years, teams of students in master's level HCI classes at Drexel University were given the assignment of designing and carrying out heuristic evaluations of the interface of the Internet Public Library. Their final evaluation reports regularly focused on what, to a usability expert, would not be considered interface issues, such as problems with finding resources in the library. These outcomes contrasted with those of a parallel evaluation of the IPL carried out by doctoral students with a background in HCI, which found interface issues to be the main concerns. A post hoc comparison and analysis of these evaluations highlights differences between users' and evaluators' perceptions of usability, and has implications for the design of digital library evaluation and the roles of users and evaluators in such evaluation.
A User-based Measure in Evaluating Academic Digital Library
2009
High demand in acquiring online academic materials, digitization of education and research materials is just not enough. Beyond that, the needs of accessing and retrieving information through the network environments has made digital library to be the right answer and choice for many. Academic digital library appears to find its niche in the world of academic society resulting dramatic changes in learning and researching environment. Like any other digital libraries, academic digital library should be evaluated so that institutions can understand how useful their academic digital libraries are to their domain of users. Literature shows that usability evaluation is in fact one of the most applied user-based approaches in evaluating digital library. It may lead and can result in improvements to system's interface. This paper reviews the literature on evaluating digital library via usability evaluation, its models and dimensions. Despite of different methods in usability evaluation study, the selection of method depends largely on the aim of the evaluation, also on aspects like the nature of the system, the targeted users and also the contents. The literature revealed that evaluating based on the aspect between user and system's interface, and between users and system's performance may not embrace the entire objective of usability evaluation. Another user-based measure is by taking into consideration on the aspect on how the digital library can suit with users' work or academic environments.
Usability evaluation of digital libraries: a tutorial
2003
This one-day tutorial is an introduction to usability evaluation for Digital Libraries. In particular, we will introduce Claims Analysis. This approach focuses on the designers' motivations and reasons for making particular design decisions and examines the effect on the user's interaction with the system. The general approach, as presented by Carroll and Rosson (1992), has been tailored specifically to the design of digital libraries. Digital libraries are notoriously difficult to design well in terms of their eventual usability.
Identification of user defined evaluation criteria for adoption of Digital Libraries – Issues in perspective
The efficacy of Digital Libraries as usable systems depends upon the extent to which they meet and measure up to the user defined evaluation criteria. The present study seeks to examine the five influencing user defined criteria deployed by the Digital Libraries viz., Usability studies, Usefulness studies, System performance studies, Impact studies and Human factor studies. It notes that usability and the collection quality are the primary and most important criteria for evaluation of Digital Libraries.
Identifying Dimensions and Their Measuring Items for Library Website Usability Acceptance Model: Instrument Development and Validation
Journal of Computers, 2018
A library website plays an enhanced role compared to its traditional physical library while providing a wide variety of library services to its users. Evaluation of library websites is a key to realize the extent of user acceptance to the website and to improve overall quality of website. Usability is a highly recognized factor to determine how easy to use the website. The models of usability evaluations evaluate the ease of use of website operations and see whether the users can perform their tasks competently. Moving on further, this study has been undertaken in context of library websites in Sri Lanka with the main purpose of exploring the relations between different dimensions of website usability and their impact. The study first investigated the common dimensions of website usability together with instrument items to measure dimensions by integrating the findings of an extensive literature review as well as discussions with local experts. The measurement instrument was then empirically validated its reliability and validity for the Sri Lankan library system with the aids of actual library users in Sri Lanka. Descriptive statistics methods and structural equation modelling techniques were applied. The proposed usability evaluation model consisted of the seven dimensions and two to three measurement items for each dimension. It is expected that this model can be used as a library website usability evaluation tool to evaluate the strengths and weaknesses of the website and update the website performance up-to-date.
