The aim off this research was to investigate user's query expansion in Google search Engine based on the "Cognitive Load Theory" and the extent and types of cognitive loads resulted from suggested keywords/queries presented in Google search engine. In this article, data were collected from 60 postgraduate students in Humanities/Social Sciences and Basic and Applied Sciences - at Ferdowsi University of Mashhad, Iran. Non- probability sampling - especially purposive sampling- was used as the sampling method. Also, individual sessions were administered with each of the students. Findings show that suggested keywords/queries and the retrieved pages do not make any significant problem (or negative cognitive load) for users. Also, there is no significant difference between students of the two fields of study regarding cognitive load in the query expansion process in Google. Approximately most of the suggested keywords/queries and the retrieved pages matched with users' needs and had direct relationship with their initial keywords. On the whole, the suggested keywords and queries have taken an appropriate approach regading more relevant results in this search engine.

The Survey, based on content analysis method, was done to analyze the application of information architecture of open access full text journals covered by SID. The number of journals covered was 88 and data were gathered through a checklist. This Survey was done in two categories: architecture of organization of information and document architecture. Results showed that in most journals, Website content to Topical method and structure of Website to network method was organized and in navigation system, use of textual bars were more than interactive ones. The use of supplemental navigation elements, specially in indexes was not in a good state. Search Formulation was mostly flat and basic and labeling of the contents of the websites were approximately acceptable. Elements related to the hypertext environment were rarely applicable in the article level. The status of the use of abstracts, keywords and figures was fairly acceptable. At the Table of contents level, page of 77 journals (87.5 %) and at article level, page of 49 journals (55.7 %) consistency in layout was applied. Failure to use the Dublin Core metadata and weaknesses in the information content of meta-metadata elements shows little attention by journals to the capabilities of these elements. At the start page level, websites of all journals and at the table of content page level of 82 journals, the HTML was used as storage format. Results indicate that the states of the application of information organization architecture elements were acceptable in contrast to the elements of document structure which were not hopeful.

This research aims to study the information security in Iranian digital libraries. The research method was survey, and the data were collected using a questionnaire based on ISO I IEC 27002 information security standard, which includes 11 indicators and 79 sub-indicators. Evaluation indicators were Security policy; Organization of information security; Asset management; Human resources security; Physical and environmental security; Communication and operations management; Access control; Information systems acquisition, development and maintenance; Information security incident management; Business continuity management; and Compliance. 45 libraries out of 58 active Iranian digital libraries answered the questionnaires.The results showed that the mean value of information security of Iranian digital libraries is 79% (from total mean of 1) and libraries are at strong level in terms of information security. Security Policy and human resources security were the most vulnerable areas of security both with the mean value of 63%. The highest security with the mean value of 1 belongs to Imam Khomeini's Portal, Niroo Research Institute Digital Library, Digital Library of Academy of Arts, Human Science Digital Library of Tehran, Digital Library of Khorasan Regional Electric Co, and Tabriz University Digital Library. In terms of information security 75/55% of the total Iranian digital libraries were at strong level, and 24/46% were at moderate level. There was significant difference between Iranian digital libraries in terms of information security, but the difference between information security in academic digital libraries and non academic ones was not significant.

The aim of this study was to find the relation between social capital and the practice of knowledge management (KM) in university libraries of Mashhad. Two questionnaires were used in this survey for collecting data. The first questionnaire was adopted from Nahapiet and Goshal's organizational social capital assessment instrument. Its aim was to assess the status of social capital in university libraries. The second one was designed by the researchers in order to investigate the opinions of librarians of university libraries with regard to the extent to which they implement KM activities in their libraries. The results showed that there is a significance relationship between social capital, cognitive social capital, structural social capital, relational social capital and the implementation of knowledge management. Among the dimensions of social capital, the relational dimension is most associated with the implementation of knowledge management.

The aim of this study is to find out the role of effective factors in accepting and applying information communication technology (K'T) according to Roger'S theory of the Publication of innovation among the rural youth of Oramanat region. The theoretical framework applied here is based on previous internal and foreign researches and a combination of sociological theories and information society. The experimental model inferred includes individual, cultural, economical, social and population factors, information sources, factors or characteristics related to innovation were studied as independent variable and accepting and applying lCT is as dependent variable. The research is carried out in a descriptive-measurement method and the population studied here,is formed of 45635 rural young people of 15 to 35 from the four towns of Oramanat (Paveh, Jawanrood, Rawansar, and Salas-e-Babajani) among those who have used lCT and are known as users. A sample of 170 youth were seleted through accidental, categorical and proportional sampling method. Questionnaire developed by. Mostafa Azkia and colleagues was used for data collection. After taking hypothesis test, the results indicate that variables of usefulness, the ease of use and type of occupation have had influence on the rate of accepting ICT, and compatibility of "ICT" and education rate have no influence on accepting it. Also, there is a meaningful relationship between the variables training rate, enjoyment from communicational channels, and applying "ICT", and no meaningful relationship was found between individuals economical basis and applying "ICT".

Purpose: Back of the book index are known as a way to find information easier and faster way than referring to the table of contents and even browse the text under study, So in this study we have paid attention to evaluate back of the Persian book index in the field of library and information science in the years 1385-1389 with regard to the criteria of ISO 999-1996 standard.Methodology: This is a Quantitative survey study, and type of research is descriptive- applied project. We have made use of case study because of the nature of the subject as well as the aim of the study. In order to analyze data we used descriptive- inferential statistics. Also statistical test including Chi- square (c2), Pearson correlation and analysis of variance (ANOV A) were applied to test the research questions.Findings: Result of present study showed that, regarding 169 books investigated in LIS field only 37.27% have back of the book index. Although the performance of back of the book index with regard to ISO standard criteria in LIS field is better than other subject areas but the potential user's expectations are more much more.Originality/ Value: In this study, researcher explored the different or significant index with regard to ISO standard criteria assessment. This study can attract the attention of authors and publishers in this field to provide more efficient back of the book index.

The aim of this study was to review the role and place of the audio-visual archives of Boushehr IRIB Center in supporting production process of radio and television programs. Research method is metrical and collection tool is a questionnaire. The study population includes 100 employees of radio and television program makers (Producers and Directors) of Boushehr center. Based on research findings, 92.8 percent of program makers believe that they can name the audio-visual archive of Boushehr IRIB as one of the main factors in the production process of radio and television programs and considered it as the anchor of program makers. 96.9 percent of the archive developers consider the center as of a database and programming supporter. 95.9 percent of program makers believe that the audio-visual archive of the center is not only a place for maintaining the resources, but also it is one of the most important parts to preserve the content and message in the media. From the viewpoint of planners, the richness of archival resources of the center has a significant role in providing and supporting, in the quantitative and qualitative promotion of production, and in time and cost reduction of programs. Most program makers consider the provision of services by the center's archivists as desired in fulfilling the information needs of program makers. The most important expectations by the center's archivists include the digitizing and richening of archival resources, developing an archive database, producing visual effects with high quality, keyword extraction of thematic resources, creating alteration and multiplying resources. Their problems include lack of access to archival resources of others broadcasting centers, lack of technical facilities in the archive, staffing shortages and closing of the archive center on official holidays.

The aim of this paper is to investigate the necessity of developiong an emergency plan in libraries/archives. Emergency situation is an unpredictable situation that can cause damages to the staff, buildings, collections and archives. It can be natural or man-made. Emergency response is the action to minimize The future damages. Emergency plan is the action that guarantee the security of staff, collections and buildings in emergency situations. The most important problem is security and prevention of disaster in the library/archive. Alhough the safety and security of people are the first priority, but particular care must he taken to The protection of collections. Facing severe disasters the impact of external factors can be within control with an emergency plan.

Objective: The present research aims to assess knowledge sharing infrastructures in library and information science departments which, in this context, include 1. To determine effective platforms based on LIS educators' attitude, 2. To find out the platforms provided by universities that they work, and 3. To identify the most common methods used for sharing knowledge among LIS educators. Methods: The methodology of this study is based on survey research. The instrument for collecting data was questionnaire and the research population consisted of 120 faculty members working fulltime in the universities affiliated to the Ministry of Science, Research & Technology and to Azad universities. Out of this number, 93 questionnaires were returned, giving a response rate of 77.5%. Findings: Based on the educators' attitude "emails, workshops, conferences and journals" are the most effective platforms for sharing knowledge. The research showed that providing knowledge sharing platforms by universities is under the average level. In fact there is a gap between what LIS educators considered as effective platforms (such as conferences, workshops and scientific journals) & what w, sharing knowledge through "formal meetings, participation in conferences, email and discussion groups & publishing articles in journals" are the most common methods used by LIS educators. Finally there is a relationship between platforms and methods used for sharing knowledge by LIS educators. Originality/ Value: This study contributes to the promotion of knowledge sharing. Additionally it helps university administrators to develop knowledge sharing platforms based on their faculty needs.

Objective: In this study we tried to measure the impact of information literacy of public librarians on library performance indicators including loan, membership, and visit activities.Method: For this purposeT we planned a survey. A questionnaire of Information Literacy was distributed among librarians in 32 public libraries in Tehran who were selected randomly. The aim was to measure the score of information literacy among them. Then the number of loan, members, and visits in the year 1389 were extracted from each library and were matched with the librarian's information literacy scores. The Pearson correlation coefficient was used to show the effect of information literacy on these performance indicators.Results: According to the research findings, information literacy of public librarians in Tehran is higher than the average. But information literacy of librarians has no significant correlation with the performance indicators.Originality / value: We showed that there is a fundamental problem in organizing public libraries in line with the conditions and needs of our society. This problem causes the information literacy of librarians to be ineffective on the library performance.

Introduction: Information retrieval (IR) systems play an important role in the collecting and availability of information and knowledge. Uses of the web and search engines as a daily life activity are associated with these systems. Because of their importance, performance and impact on the information behavior process, this combination requires a quality review and evaluation.Methods: This article is a review and analytical/critical approach.Results: This paper first looked at the evolution of IR systems and has separated the types of IR systems evaluation. Then in a more detailed account, the performance evaluation of existing approaches to IR systems is discussed. After a review and criticism of these approaches, the paper has introduced a comprehensive and integrated multiple criteria decision- theoretic approach for the evaluation of IR systems provided by Wang and Forgionne.Conclusion: Researches on the evaluation in the field of IR have mainly focused on one of the aspects, and different approaches have been separated. The main challenge in trying to evaluate IR systems is is how to apply a variety of scales, in an integrated and comprehensive approach. This shows the direction of future researches in this field. The research presented in this paper which is based on above approach can advise researchers in this field.

Today more information resources are published in electronic and digital formats and they are available on the web. The production, distribution and storage of information are easily possible on the Web but theie retrieval is a challenge to the user. Researchers in various fields, including library and Web designer's communities, are thinking about the solutions to solve these problems. Developing the Resource Description and Access (RDA) by the Joint Steering Committee as a successor of the Anglo-American Cataloguing Rules, Second Edition, base on conceptual models and International cataloging rules developed by the IFLA and the emergence of the Semantic Web and its models, including Resource Description Framework (RDF) by The World Wide Web Consortium are examples of solutions to provide efficient description of information resources and present the conceptual relationship between them on the web environment.This study attempts to make librarians and catalogers familiar with RDA, Semantic web and RDF, one of the standards of semantic web. It also attempts to adapt entities and vocabularies of RDA in RDF that was based on cooperation between the Joint Steering Committee and the Dublin Core Metadata Initiative. In the end the eXtensible Catalog which has been designed based on RDA, FRBR and RDF is introduced.Also, the basic attention to the underlying structure and models of RDA and similarities that this standard has with RDF in information storage and retrieva for increasing functionality of information retrieval systems have been analyzed.
