This article identifies the use of a variety of standard formats for storing video, text, multimedia and audio resources in the digital collections of 20 selected national libraries around the world. This study is applied, based on descriptive-analytical method. For data collection we used researcher-made questionnaire. After collecting data, a variety of descriptive statistical techniques such as frequency distribution and frequency percentage and Chi-square test were used to analysis the dat. Based on the results, it was found that image sources were used in all studied collections and cultural objects were less popular with a share of 41%, for TIFF image sources (94%); HTML and XML text sources (75%); WAV audio sources (65%) and AVI multimedia sources (65%) were the most common. The research community had the least amount of diversity of use in the field of multimedia resource storage research findings emphasis on the use of EPUB for ease of reading books on e-readers, GP3 was recommended to increase the usability of the mobile version of the digital library, WARC as a special format for web archiving, for long-term protection of digital content of national libraries, because these three The format had the lowest usage in the statistical community.

Awareness of users' perceptions and interpretations of the information labels of the user interface of digital library of the NLAI. The present study was an applied research with a mixed method. Data were collected through a researcher-made questionnaire, interview, and observation. Through a exploratory method, participants were asked to spend considerable time and in-depth to examine the categories, elements, and labels used in the digital library website and to determine their understanding of the website labels in the online questionnaire in the form of a Likert scale. Then, the semi-structured interview technique was used to study users' perceptions and interpretations of the labels assigned to the elements on the website. The study population included users of the digital library of the NLAI, which was selected in two groups of novice users (clients) and advanced users (librarians) of 20 people (10 novice users and 10 advanced users). In order to validate the research results, Methodological angulation was used to increase the reliability of the research data. During this method, the researcher used several methods to collect data (using interviews with observation, exploratory study, and questionnaire), as well as all research strategies and steps with the necessary documentation at the time of data collection were recorded. Finally, after collecting the data, the researcher used the Member checking method. During this quality control process, the researcher asked the 7 participants to read the notes and the results of the data and express their opinion on the accuracy of the findings. Cronbach's alpha test (0.85) was used to ensure the reliability of the data collection tool and the possible problems of the questionnaire. SPSS software was used to analyze the research data. Content analysis and Excel software were used to analyze the interview data. The results showed that the final average of comprehensibility of labels and terms used in the website is over 50% and indicates a good understanding of the terms and labels used in the website to represent information categories, but some labels need to be changed and updated. Some terms are not very understandable from the users' point of view and need to be revised, such as: "review", "quick look", "typical classification", "source registration", "legal considerations", "main site", "texts", "Periodical" and "Collection". The friendliness and user-friendliness of the words on the website, and the ban on the use of specialized, complex, and ambiguous words were among the demands of the users. New terms and labels were suggested by users. The use of specialized library terminology on the website, intangible and abstract words and lack of sufficient explanations about labels, lack of a comprehensive guide, going into more detail, complications on the website, and inconsistency in the use of words for similar concepts are some of the problems that cause the user does not have a good browsing experience.

The purpose of this study is systematic reviewing of organizing metadata standards to find the status of researches in digital libraries. The research attempted to categorize them in terms of the functional area and role that they play in digital libraries. By identifying the statue studded standards, it is possible to determine the functional place of other standards that expanded in the digital library area and are functionally similar to covered standards in this research. In this way, systematic review was used for study. By searching the databases, finally 42 research sources were selected for final review. Findings showed that the organizing standards, based on they role in digital library, could be categorized in seven sections (include Resource description, Resource structure determination, Resource management, Resource content organization, Local format definition in digital library database management system, Semantic context and interoperability). Then, a set of standards in each area were identified (50 standards in total). The results finally showed that MARC with 60.5%, DC with 44.7% and OAI and MODS with 42.1% were the most known standards. Audio-MD, VIDEO-MD with 5.3% also were the most unknown.

This descriptive survey evaluates the digital libraries of Allameh Tabataba’i University and Tebyan Cultural Institute based on the Xie and Joo (2013) digital library evaluation criteria. A checklist was made based on information from 10 structural dimensions of digital library evaluation criteria. It was then set up as a researcher-made questionnaire based on the Xie and Joo digital library evaluation criteria. To collect data, questionnaires were distributed among librarians and users of the two digital libraries. Sixty-three valid responses were collected and analysed with SPSS software .Findings showed that the two digital libraries were in a moderate condition in two dimensions (user engagement and context); and in good condition in the others. The findings of the inferential statistics show that there is no significant difference between users’ and employees’ viewpoints on the dimensions of the digital collection, interface design, context, preservation and administration (sustainability). However, regarding the information organization and services (level 0.01), the dimensions of technology and the effects on the user (level 0.02), there is a significant difference between the two systems in terms of the user engagement dimension with the relative superiority of Allameh Tabataba’i digital library.The results show that despite the differences in the type of these two libraries, there is not much difference between the studied dimensions (other than those mentioned in the findings), but in some dimensions, there is a slight difference between the respondents' opinions. It is seen with the relative and partial superiority of Allameh Tabataba’i digital library.

This study investigates the factors affecting users' understanding of digital libraries with emphasis on Allameh Tabataba'i University Digital Library.The method of this study is descriptive-analytical and it is a purposeful one. All students of Allameh Tabatabai University were the statistical population of this study(18000 students) out of which 378 students were selected using simple random sampling method. Due to the lack of a standard questionnaire, a researcher-made questionnaire was used. The questionnaire used for data collection consisted of three demographic questions (gender, digital library experience and educational level) and eight components with 25 closed questions including system quality, information quality, service quality, usefulness, ease of use, digital library Affinity, user satisfaction and user loyalty. Data were analyzed using t-test, independent t-test and ANOVA, at significance level α = 0.05.: The findings showed that considering the calculated significance level, all factors affected students' perception of digital library of Allameh Tabatabai University including system quality (-39.88), information quality (-57.425), service quality (571.721) -), usefulness (-66.320), ease of use (-49.558), digital library Affinity (-60.944), user satisfaction (-61.497), and user loyalty (-60.488).
