Background and Objectives: The user interface of libraries' websites has a decisive role in optimal performance, and libraries can, when they can, have a good performance so that users can communicate with them. In this research, from the viewpoint of Library and information professionals, and from the point of view of compliance with the Nielsen ratings, it has been examined whether these criteria have been addressed in the design of the UI web site. The purpose of the present study was to evaluate the interface of the National Book Web site of the Islamic Republic of Iran and the level of compatibility of this website with Nielsen's components in a revealing approach. Methodology: The present study was a survey based on revelation evaluation. Nielsen's Revelation Assessment was first described in 1990 at the Human-Computer Interaction Conference, which included the use of a small set of evaluators to check the user interface environment and to judge that the user interface features are matched with pre-defined check log criteria. Simple random sampling has been used to choose, but considering that in the user interface studies with an opposite approach, it is better to use expert data. In this research, two main criteria were the criterion for selecting the evaluators. Therefore, 37 individuals were selected randomly, which had two conditions: 1. having a minimum undergraduate degree in librarianship and apprenticeship; 2. Understanding the concept of the user interface. Cranach’ s alpha coefficient was used to assess the validity of the check list. The results obtained with 77 questions on the 37 users showed that its alpha coefficient is equal to 0. 96, which is a high coefficient. In order to assess the validity of the check list, Content validity method was used in this study. Findings: In this research, the pattern of revelation that has been identified by numerous studies as a valid universal model for measuring the user-environment utilization has been used to evaluate the user interface environment. The results of the study showed that the degree of compliance of the interface with the " The clarity and feasibility of the system", " the correspondence between the system with the real world", " stability and consistency", " aesthetic aspects and simple design", " recognition instead of reminding messages ", the components of "user control and release", "helping the user to prevent and correct errors", "flexible and system efficiency", "guidance and documentation" are modest, and the level of compliance with the "error prevention" component is very low. Also, the results of the evaluation indicate that on the website of the National Library of Iran, the criterion of control and freedom of action of the user of the website, with 37. 84 percent of the criteria, is more consistent with the criteria than the other components and the criterion of error prevention with a minimum of 19. 5 percent compliance is the least consistency. The Nielsen component has ten components. To further benefit from the website of the National Library of Iran, the problems in the web interface that interfere with the users' perception should be identified so that designers of the environment try to resolve their work problems. Considering that in this research, it has been attempted to review the problems of the system by observing all the problems of revelation, it is still possible that there would be problems that the evaluators have left behind. One of the problems found on this site is the bustle and confusion of the UI page. It is not possible to define a different user interface for specific user groups. Data analysis showed that the interface of the website interface of the National Library of Iran with 10 components of Nielsen is generally higher than the average. This website did not have a desirable standard on some of the Nielsen model. Discussion: The review of the findings of the study on the degree of compliance with the criterion of visibility of the status of the system suggests that users believed that the website of the National Library of the Islamic Republic of Iran will alert them to a great deal about what is happening through appropriate feedback. Also, regarding the compatibility measure between the system and the real world, the result showed that the user interface of the National Library website is largely consistent with this criterion. It seems that the user-interface designers of the National Library of the Islamic Republic of Iran website has been working more towards alignment between the system and the real world. The goal of each site is to help users to interact more with the system; therefore, compliance with this criterion is the focus of attention on the user and his needs. Web site control and users’ freedom of action has a special place in the user's minds, which attracts them and creates interest in them, increases user interaction and facilitates user interaction. The status of this benchmark is modest on the website of the National Library. Considering the importance of the flexibility and system efficiency, it seems that the designers of the website of the National Library of the Islamic Republic of Iran should place more emphasis on the components of the "possibility of color change", in specific cases by the user and "the possibility of personalization of the way information is displayed" in order to reach the desired level in terms of the "flexibility and system efficiency" criterion. Given the importance of benchmarking user assistance in identifying and correcting errors, the National Library website designers need to focus more on the components of helping users identify errors and fix them, informing users of possible errors and applied issues, so that this criterion lead to the expected and desirable situation for users. In the "user control and freedom" criterion, it is not possible to define a different user interface for specific user groups, as well as non-personalization of displaying existing information.

Background and purpose: The Library website acts as a scientific gateway to communicate with researchers and students, and these websites can meet their information needs if they have the desired information architecture. The purpose of the current research is to evaluate the website of Astan Quds Razavi Digital Library based on information architecture indicators. The research method is applied and descriptive, and the checklist was used to analyze the organization system, tagging system, navigation system, and search system of the website according to the three layers of the information architecture (content, user, and context). The results of the inspection lists showed that the Astan Quds Razavi Digital Library website scored 23 out of 37 points in the organization section, 44 out of 57 points in tagging, 55 out of 78 points in navigation, 26 out of 46 searches; To increase the level of user satisfaction and the efficiency of websites, it is necessary to fully implement the principles of information architecture in their design; By identifying the weak and strong points of the website, this research can be a suitable source for planning regarding the optimization of the website architecture. This research tries to express the weaknesses and strengths of this website and its effectiveness by providing a systematic evaluation of a case study for the Astan Quds Razavi Digital Library website. According to the findings of the research, the website is in good condition with 62%, 77%, and 70% points respectively in the components of organization, labeling, and navigation systems; The weaknesses of the organization plan were more than the type of organization structure. The lack of geographic, audience-oriented, and organizational chart-based plans and the lack of support for social classification are among the most important weaknesses of the website organization system. Not using sequential labels was one of the most important weaknesses of the labeling system; Failure to implement the local navigation system and site map is one of the weaknesses of the navigation system. With 56% points, the search system is in an average condition and cannot correct typos in the input query, remove stop words, find words with the same pronunciation as the input query, find words with the same string as the input query, and rank the search results. The identification of the results based on the relevance of the ranking is one of the weaknesses of the search system.

The purpose of this study was to explore the users’ experience of web content of the National Library and Archive of Iran. To investigate the user experience, a contextual inquiry was conducted to gain an in-depth understanding of users and the context of their real work. Data analysis was also used to complete the results. Contextual inquiry is an interpretive and qualitative approach in the form of semistructured interview which is based on conversation with users. “ Sentence completion” is a kind of UX method in which users completed some statements about the website of the national Library and archive of Iran. The results revealed eight general categories about the user expectations and experiences on the web content of National Library and archive of Iran, including search, research utilities and knowledge development, personalization and customization, Library space and in-site location, interaction, events, information architecture, and design and appearance. The results provide proper basis for the development of the website of national Library and archive of Iran and similar libraries as well as digital Library software. These results, along with suggestions for improving the user experience of the National Library Web site, provide valuable ideas for entrepreneurs and business startups and app designers about real needs and expectations of users.

The present study carries out a quality assessment of the Library websites in Iranian State Universities in order to rank them accordingly. The evaluation tool used is the normalized Web Quality Evaluation Tools (WQET). 41 Active Library websites were studied and assessed qualitatively over two time periods (Feb 2006 and May 2006) using WQET. Data were collected by direct observation of the website.

Introduction: Computer-based systems have become integral to every aspect of daily life, with the successful performance of such systems heavily reliant on error-free software. Given the significance of these systems, tools are essential for evaluating their usability. One such tool is the Post-Study System Usability Questionnaire (PSSUQ). The present study aimed to localize and psychometrically evaluate the Persian version of the third edition of the PSSUQ and assess the usability of the Library website at Mazandaran University of Medical Sciences. Material and Methods: This descriptive cross-sectional study employed the Backward-Forward method for translating the questionnaire. The study population included 314 participants for cultural adaptation of the scale and 147 postgraduate students for evaluating the Library website, all from Mazandaran University of Medical Sciences. Content validity was assessed using the Content Validity Index (CVI) and Content Validity Ratio (CVR). Reliability was determined via Cronbach’s alpha, and exploratory factor analysis was performed. Data analysis was conducted using SPSS version 16, adhering to ethical guidelines at all stages of the study. Results: The overall content validity index (CVI) of the questionnaire was 0.96, while the overall content validity ratio (CVR) was satisfactory, with clarity and simplicity both scoring 0.91 and necessity at 0.75. Cronbach’s alpha coefficient was 0.95, with correlations between items exceeding 0.30. No significant differences in the usability of the Library website were observed based on age, gender, field of study, educational level, or year of admission. Conclusion: The Persian version of the third edition of the PSSUQ is a valid and reliable tool for evaluating system usability and user satisfaction with digital systems. It holds substantial potential for identifying system weaknesses and areas requiring improvement.
