Designing green websites using green user interface components improves their energy expenditure efficiency. This research aim to identify the strengths and weaknesses of the Iranian digital libraries’ websites according to the UI Green metric criteria. This applied study adopted a webometrics approach. Our research population was 59 digital libraries’ websites. Our tool was a researcher-made checklist. Experts certified its validity. Its reliability was confirmed using Cronbach’s Alpha test (alpha=0.758). Websites were evaluated both by two online tool and by website advisors and designers. We analyzed data using descriptive and inferential statistics (binomial and chi-squared tests). Our results showed a significant difference in user interface design between the studied websites (P=0.030). Most websites(28.8%) are middle-level. Academic (25.8%) and non-academic digital libraries (28.6%) are at a good level. Ranking the Iranian digital libraries showed that the digital libraries of Payame Noor University(by Ertebatat Payme Mashregh Engineering Co.), Fatemeh Masumah Holy Shrine (by Pars Azarakhsh), Astan Quds Razavi (by Astan Quds Razavi Holy Shrine) are in the excellent level by scoring the total 25 points. Two digital libraries, the digital library of Iran University of Medical Sciences (by Yekta Web Afzar Shargh Co.) and Mashhad University of Medical Sciences (by Pars Azarakhsh Co.), are in the last place in complying with the intended components by scoring 7. Iranian digital libraries have an above-average status in using the green user interface. Furthermore, the green user interface components of academic and non-academic digital library websites were in good level.

The purpose of this study is to use ontologies in the information retrieval of digital collections with an emphasis on images. The present research is of applied type and has been done by library method and systematic review of resources with an analytical approach. Using this method, the sources were collected around the research axis and selected for a more detailed review, and finally, the sources were reviewed according to specific and systematic instructions. In this method, all research in the field of ontology and its effect on image retrieval has been reviewed. The research findings show that image retrieval techniques, considering the backgrounds, include: text-based image retrieval, content-based image retrieval, composite model image retrieval, and semantic (conceptual) retrieval that used related feedback schemes to improve performance as well as the accuracy of the image retrieval process.Most of the researched studies have emphasized the necessity of using ontologies in digital collections. Therefore, in the current situation, we are moving towards the Semantic Web in order to organize digital images that deal with various structural and linguistic problems such as ambiguities, doubts, and human metaphors for the machine, and the use of ontologies. It is very effective in improving accessibility and retrieval accuracy.

The present study offers a comparative analysis with exploration approach among university library websites in Iran and United States from standpoint user engagement via social medias. Descriptive survey method was used in this study. Websites composed of 21 academic university library websites in Iran and 16 academic university library websites in United states (37 websites) were investigated by direct observation using analytical database “similarweb“ during 3 months (February up to April 2019). Findings showed that in United States, 100% of the total university library websites attracted users through social media, compared to 19% in Iran. The number of users clicking or visiting the website of the university library via social media in Iran was 3% of the total number of users visiting the library's website. This figure in United States was up to 1% (Except for the MIT University libraries that the number was 11%). Facebook, YouTube, Twitter, Reddit, Researchgate and Pinterest were the top media that university library websites in United States had user engagement through them.

The purpose of the study is to orient the Digiqual model with the 5S theoretical framework in digital library concepts. The research type is practical and it was conducted using the analysis of qualitative content method. The validity of the research is a logical one which is based on personal subjective judgment. The reliability of the study is a type of credibility based on counseling the specialists in the field of digital libraries. In the digiqual model, content (information) and community (user) as two processes in digital libraries are related to technical environment and human/system interaction. Societies (actors) as a factor in dimensions of some ‘S’ concepts in digital libraries, including accessibility and pertinence of the digital object and also availability, effectiveness, extensibility, reusability and reliability of services, is appreciable with digiqual model. Scenario as a factor in dimensions of ‘S’ concepts in digital libraries including pertinence, and conservation of the digital object; availability, effectiveness, extensibility, reusability and reliability of services, is appreciable with digiqual model. Streams and structures as factors in dimensions of some ‘S’ concepts in digital libraries including accessibility, conservation, relevance, similarity, significance and timeliness of the digital objects; accuracy, completeness and conformance of metadata specification; completeness as a collection; completeness and consistency of the catalog; completeness and consistency in the repository; efficiency and effectiveness of services, is appreciable with digiqual model. Space as a factor doesn’t exist in any of the ‘S’ concept dimensions in digital libraries and it is not appreciable with digiqual model. Finally, the development of ‘S’ concepts in digiqual dimensions in order to integrate the quality of services is proposed.

This study aimed to assess the technical aspects of user-system interaction quality in digital library of Pasteur Institute using DJ Qual. It is a survey-based, descriptive and applied study. The statistical population consisted of 177 faculty members of the Pasteur Institute. Using Cochran sampling formula, 118 members were selected as sample population. In order to collect primary data for the research, field study (questionnaires) has been implemented. The questionnaire used has been drawn from the DJ Qual standards and localized to evaluate the quality of the library services of Pasteur Institute. Results showed that users in status and in the optimum level of availability, reliability, accuracy, coverage, active links, browsing and organizing digital library of the Institute Pasteur technical aspects of consent The largest mean difference between the current and desired status was 1.83, assigned to the variable ‘active links’ and the smallest difference was 0.34, assigned to the variable ‘accuracy’. According to the findings of the research, comparative studies are needed at the level of academic and research centers in order to obtain more knowledge about the facilities and infrastructure of these libraries.

This study aims to conceptually analyze the Delos reference model and the 5S Framework and to identify key relations between the concepts and indicators of the model and the framework in the organization and evaluation of digital libraries. The research method is conceptual analysis of Delos reference model and 5S Framework in the organization and evaluation of digital libraries. The Delos reference model focuses on the identification of core concepts and relations that encompass a digital library, while the 5S Framework focuses on the concepts of information and knowledge organization. The six areas of Delos reference model include content, user, functionality, quality, policy, and architecture that explain the core concepts and relations of digital libraries in a transparent and structured manner and are used as a foundation for evaluation of digital libraries. However, the 5S Framework mostly focuses on explaining key concepts and information organization in digital libraries such as digital objects, metadata, sets, and services. The organization of the three separate systems (digital library, digital library system, and digital library management system) in the same framework has made the Delos reference model complicated. However, the 5S Framework simply depicts all activities and services of a digital library in five processes. The Delos reference model, compared with the 5S Framework, lacks a strong emphasis on the social aspects of digital libraries. The Delos reference model and the 5s Framework can assist digital library designers in organizing, designing and evaluating digital libraries for coordination of practices, solutions, and development and integration of digital library systems. The Delos model and the 5S Framework have common relationships with digital libraries in the areas such as streams, content, communities, and users.
