The purpose of this paper is to statistically explore the relationship between web usability and web presence of the universities. As a case study, five Turkish universities in different rankings which were selected from Webometrics rankings were evaluated and compared.

Two different methods were employed for performing usability evaluation of the selected universities: a user testing was used to measure the user performance on the selected tasks and a questionnaire to assess the user satisfaction on the website use. Both usability evaluation methods were applied on the pre-determined tasks for each university by participation of 20 subjects. After the usability evaluation, the universities were ranked in terms of usability results and finally, the relationship between web usability and web presence of universities was statistically investigated by using Kendall’s rank correlation.

Several common usability problems which were asserted by related previous studies were identified at the end of usability evaluation of university websites. The usability results also revealed that selected Turkish university websites suffer from numerous usability problems. Further, a strong positive correlation (p < 0.05) between the usability of the university websites and their web presences were identified. Hence, the participants showed a higher success and satisfaction while performing the tasks on the university websites which have strong web presences.

The findings from this study have practical implications for universities. Correlation results showed that universities can improve their web usability by giving importance to their web presence volumes. Universities can estimate their web usability levels by investigating their web presence rankings and they can also raise their rankings in Webometrics ranking system by improving the usability of their websites. Moreover, university web developers can design more usable and more user-friendly websites by avoiding usability and design problems identified through usability evaluation.

Different from the prior research efforts focussing on usability of educational web pages, this study contributes to the growing literature by statistically exploring the relationship between web presence and web usability of universities. This study is also precious from the point of view that it is one of the first attempts to evaluate and compare usability levels of a set of universities’ websites from Turkey.

This paper aims to report on a web usability study and to identify and prioritise key web interface usability factors (WIUFs) for web sites of 36 student‐related online services categorised into three groups: personal services, purchase services and study‐related web sites.

In this study, involving 400 student internet users (SIUs), 12,310 data points were collected and analysed using a multiple linear regression test. Seven WIUFs were tested: use of colour and font (UCF), use of graphics and multimedia (UGM), clarity of goals in web site (CGW), trustworthiness of web site (TOW), interactivity of web site (IOW), ease of web navigation (EWN), and download speed of web site (DSOW).

The study results reveal that every online service category has a different set of crucial WIUFs. SIUs' web usability preferences were compared with those of general internet users.

The participants were all Malaysians; therefore, generalising the findings to all SIUs will require a confirmatory study with SIUs from other parts of the world.

Web developers can use the results to design usable web sites for specific online service categories.

The research offers a simpler alternative to measure web usability and to determine which WIUFs are crucial for a specific online service category with consideration of the users' role. This study overcomes some weaknesses of previous studies, i.e. small sample size, no consideration of product‐task relationship, no specific customer group and cumbersome procedures.

This study aims to develop a measurement instrument, which involves four usability dimensions of efficiency, effectiveness, satisfaction, and learnability, as a way of assessing the usability of academic digital libraries.

To generate measurement items, previous research related to usability frameworks, usability guidelines, and empirical usability tests was reviewed. The measurement instrument was then verified in terms of reliability and validity, empirically using data from 230 actual users of an academic digital library. To ensure the reliability of the instrument, internal consistency of measurements, measurement item reliability, and construct reliability were examined. Construct validity, which consists of convergent validity and discriminant validity, was also examined on the basis of confirmatory factor analysis using structural equation modeling.

The usability evaluation instrument suggested in this study comprises four dimensions: efficiency, effectiveness, satisfaction, and learnability, and three to four items were identified to measure each dimension.

To date, while many of the usability studies have relied on either experimental methods or inspection methods, few studies have been conducted to identify evaluation measures that can assess the usability of a digital library from a survey method. This study is one of a few studies to develop a measurement instrument tailored to academic digital library environments.

Usability studies are a form of library evaluation that are often passed off as research. However, at its core, usability is an evaluation method, not a research method. The goal is to make an argument that usability studies can be a valid form of scholarly research if certain limitations inherent in usability studies are addressed in the research design.

Through evaluating literature in the social sciences, this paper makes an argument for usability as a research method if certain limitations inherent within usability testing are addressed.

Usability is not only an evaluation method, but when limitations are addressed; it can be considered an important research tool within libraries.

No other article in the library and information sciences literature talks about methodologies for usability. Most usability articles do not address methodologies utilized in a way that would be considered research in a broader social sciences context. This article bridges the gap from when usability is considered evaluation to when it is considered research within library science.

The present study aims to review the literature concerning Digital Libraries (DLs) and user interfaces in order to identify, determine, and suggest evaluation criteria for a DLs user interface. Accordingly, this study's objectives are threefold: explore which criteria exert a significant relationship with the DLs user interface; identify a set of criteria that appears to be useful for evaluating DLs user interface; and determine evaluation criteria that have more frequency and occurrence in the related texts reviewed.

To do it, first, identifying related texts was necessary. Consequently, keywords such as “DLs user interface evaluation”,” DLs user interfaces”, “DLs evaluation”, “DLs usability”, “user interface evaluation”, “DLs research”, “web sites user interface evaluation”, “user interface standards”, and the like have been searched in the web as well as in some leading databases including Emerald, Proquest, SagePub, ScienceDirect, LISA, ERIC, ACM, and Springer. After identifying and accessing more than 100 evaluative works and some related articles, theoretical and empirical, nearly 50 sources were chosen for final examination.

After reviewing related texts, three major categories are identified: user interface and DLs; DLs and usability; and other studies related to user interface; each one of three identified categories has its own subcategories. Additionally, 22 evaluation criteria for assessing DLs interface have been identified.

The review does not claim to be comprehensive.

Hopefully, criteria such as feedback, ease of use, match between system and the real world, customization, user support, user workload, interaction, compatibility, visibility of system status, user experience, flexibility, and accessibility which have been less considered should be applied more in future, particularly user‐oriented, studies. Furthermore, it is expected that criteria mentioned here could help related bodies pay more attention to the evaluation of EISs, especially DLs interface.

It can be said that this study has contributed to the research into the evaluation of DL interface.

This study aims to explore whether the usability of user experience for mobile library application plays a mediating role in the relation between the success factors of information systems and net benefit.

The theoretical model of “information system success factor–user experience usability–net benefit” was constructed. A questionnaire was conducted at the Nankai University. The mediating effects of the usability of the mobile library application on information system success factors and net benefit were examined using hierarchical linear regression and structural equations.

First, the usability of user experiences is positively correlated to information quality, system quality and service quality. Second, user experience usability has a significant mediating effect on the relation between information system success factors and net benefit.

This study improves upon the DeLone and McLean model, connects the usability of user experience with the model and constructs the success factor mechanism of the mobile library application. It provides a theoretical basis for interpreting the relation between the mobile library application and users.

The main objective of this paper is to review work on the usability and impact of digital libraries.

Work on the usability and impact of digital libraries is reviewed. Specific studies on the usability and impact of digital libraries in specific domains are also discussed in order to identify general and specific usability and impact measures.

The usability studies reviewed in this paper show that a number of approaches have been used to assess usability. In addition to the technical aspects of digital library design (e.g. architecture, interfaces and search tools), there are a number of usability issues such as globalisation, localisation, language, culture issues, content and human information behaviour. Digital libraries should, however, be evaluated primarily with respect to their target users, applications and contexts.

Although a digital library evaluation study may have several objectives, ranging from the evaluation of its design and architecture to the evaluation of its usability and its impact on the target users, this paper focuses on usability and impact.

This paper provides insights into the state‐of‐the art in relation to the usability and impact of digital libraries.

The purpose of this paper is to provide an integrated list of heuristics and an information architecture (IA) framework for the heuristic evaluation of the IA of academic library websites as well as an evaluation framework with practical steps on how to conduct the evaluation.

A set of 14 heuristics resulted from an integration of existing usability principles from authorities in the field of usability. A review of IA literature resulted in a framework for dividing academic library websites into six dialogue elements. The resulting heuristics were made applicable to academic library websites through the addition of recommendations based on a review of 20 related studies.

This study provides heuristics, a framework and workflow guidelines that can be used by the various evaluators of academic library websites, i.e. library staff, web developers and usability experts, to provide recommendations for improving its usability.

The focus of the usability principles is the evaluation of the IA aspects of websites and therefore does not provide insights into accessibility or visual design aspects.

The main problem that is addressed by this study is that there are no clear guidelines on how to apply existing usability principles for the evaluation of the IA of academic library websites.

The purpose of this study was to evaluate the usability effectiveness of a webware for electronic theses and dissertations (ETDs) in Nigerian repositories. The webware (etdsearch.com.ng) is a web application system that curates ETDs from three sampled Federal government-owned universities. The system also links users to the repositories where the theses and dissertations are hosted.

The case study research strategy was adopted for the study. Sixty postgraduate students from three universities were randomly selected. A usability evaluation questionnaire based on the ISO 9241-11 framework was used to collect data after performing pre-defined queries/tasks based on the informational and transactional query models. The research questions were analysed using the median of the performance score (f_x) of the three universities for each item evaluated, while the Kruskall–Wallis test by ranks was used to test the null hypothesis at a 5% level of significance.

The study answered two research questions and tested two null hypotheses on the usability effectiveness of the webware based on the informational and transactional queries. The participants found the ETD search system effectively useable. In addition, there was no significant difference in the opinions of the participants.

The webware used simulated repositories as a feed bed for the ETDs in order to have control over the workability of the repositories. Thus, the results may differ slightly when “live” repositories are used.

The effectiveness of a webware that aggregates ETDs in Nigerian repositories will present libraries in Nigeria with evidence on how these systems work and can be improved upon.

There is a dearth of literature on practical usability studies of digital information systems in Nigerian libraries.

To address the key problem of lack of use in the advancement of open government data (OGD) portals from the aspect of good usability, which is an essential prerequisite to the acceptance and usage of a portal, this paper aims to develop a usability framework including design principles and criteria for OGD portals and to discover problems in the present usability design.

This study builds the usability framework by extending usability principles for general websites to address the specific needs of OGD portals. Criteria for each principle are developed accordingly based on the literature. A comparative heuristic evaluation involving five expert evaluators and 13 Chinese province-level OGD portals has been carried out to test the capability of the usability framework.

A usability framework with 24 principles and 63 criteria has been built. The heuristic evaluation shows OGD portals performed better in meeting general principles than the OGD portals specific ones. Insufficient help functions weakened OGD portals' usability. Similarities and differences were found of Chinese OGD portals compared with similar studies in the United States.

This paper proposed a usability framework for OGD portals and proved its capability in recognizing usability problems and its causes by carrying out a comparative heuristic evaluation in China. By comparing the evaluation results with other studies in the United States, the findings and lessons learnt in this study can thus be shared across international borders.
