Purpose: This article aims to investigate library users' satisfaction in the areas of resources, building and equipment, librarians and services within the public libraries of Yazd city.
Methodology: This is a Survey research project that uses a researcher- made questionnaire. Data was collected by a supervised and paper-based questionnaire. The research population includes active users of public libraries in Yazd city (more than 1000 users). The sample size is calculated using the Koukran formula and a total of 226 questionnaires were released.
Findings: Public libraries have satisfied users to an average degree which is promising. Librarians achieved the highest level of user satisfaction as a result of their own knowledge and behavior. Moreover, the lowest level of user satisfaction of public libraries was related to the lack of space for group study, inadequate library environments, insufficient welfare facilities, etc.

 Methodology: We used scientometric tools and methods and some of the most important social network indexes such as Collaborative Index, degree of Collaboration, Collaboration Coefficient, Degree Centrality, Between Centrality, and Eigenvector Centrality for the fulfilment of this research. Nodexl software was used to analyse data.
Findings: The results show that the most important Collaboration Index is related to Processing and Information management journal and the highest Degree of Collaboration belonged to journal of Information Science and Public Libraries and Processing and Information management journal. Moreover, the most important authors with the highest degree are included Gholamreza Fadaei, Mohammad Hasanzade and Fariborz Doroudi.

Purpose: Information and information sources can be divided into three broad categories according to their nature or type: textual information (book, journal article, conference paper, dissertation, newspaper, etc.), visual information (infographic, photo, Cartoons, films, etc.) and audiovisual information. The purpose of this study is to determine the effect of reading textual information in comparison with visual information (infographics) on the health information perception of high school girl students in Tehran.
Method: The current study was carried out by applying a semi-experimental method in which a pretest/posttest design was used on two groups. The research population included 30 high-school girl students of Boshra High School in Tehran. Two groups of 15 students were randomly selected and invited to participate in groups. In fact, 15 participants in one group read textual health information and 15 participants in another group read infographic health information. An acquaintance pre-test was performed on both groups and two post-tests of learning and retention were used to evaluate whether the participants learnt and retained textual and visual health information, which was presented to them during the period under study using a 27-item self-report questionnaire based on textual and visual information. Finally, the results of the two groups were analyzed by descriptive statistics and dependent and independent t-test.
Findings: The findings of the study showed that the mean scores of the two groups of participants were the same as in the pre-test, the difference between the observed mean scores for the pre-test scores was not statistically significant. Furthermore, the mean scores of the two groups of participants for both textual information and visual information (infographics) were equal in the post-test of learning, and the difference in mean scores for post-test scores was not statistically significant. This means that both textual information and visual information (infographics) have increased the participants' learning to the same degree and do not differ significantly in terms of learning. Additionally, the mean scores of both groups for textual information and visual information (infographics) in the post-test were also equal and the difference in observed mean for post-test scores was not statistically significant. The latter finding means that textual information and visual (infographic) information were remembered equally and were not significantly different.
Originality/value: The findings of the present study indicates that textual information and visual information (infographics) have increased the learning and retention of participants to the same extent and are not different in terms of learning and retention. It can also be concluded that despite the appearance of the formats and the media, the text still has an important place in the learning and retention of students.

Abstract
Purpose: The purpose of this study is to identify platform-based services and their priorities in order to apply them in Iran’s public libraries.
Method: This research is an applied study in terms of purpose, including a mixed approach in terms of the research framework. First, the platform-based services were identified through using the meta-synthesis method. Then, after searching through the literature and selecting the appropriate sources by meta-synthesis, 9 articles were eventually investigated as the final selected resources. Then, after the key codes were extracted from the sources and the concepts were categorized, platform-based services were identified. In the second stage of the research, a researcher-made questionnaire was used in order to determine the importance of the services extracted by 38 experts and professionals of public libraries. In order to identify the most important services based on the professionals’ views, data was analyzed by SPSS using the Binomial test.
Findings: Through the meta-synthesis applied, 28 services were extracted under 3 categories: education-oriented services (11 services), accessibility and information services (9 services), cultural and leisure services (8 services). According to the experts, the most important services to be applied in the Iranian public libraries include: three education-oriented services (teaching children how to interact, lifelong learning education, and health literacy education), five services related to accessibility and information (establishing a digital library, information consultation for entrepreneurs, access to local information, access to health information, and interlibrary loan) and seven cultural and leisure services (allocating space to groups and associations, creating space for public gatherings, providing equipment and facilities for studying or doing homework, setting up an attendance program for entrepreneurs and producers, creating space for public participation, creating space for scientific conferences, and interaction between suppliers and demanders).
Originality/value: From a platform perspective, Iran’s public libraries, should be not only a conduit for access to information and information resources, but also an interface between users and local organizations. In the area of education, public libraries should be a platform for providing education by various organizations to people; In the area of ​​accessibility, they should provide access to government, local and commercial information; In the field of cultural services and leisure, which was more important for the experts under study, in addition to being a place of communication for people, they should also use the physical space of the library as a venue for providing services. Iran’s public libraries should provide a platform for local users, organizations, companies or any other type of body to use the physical space of public libraries for official ceremonies, festivals, traditional markets and exhibitions.
