Background and Aim: this study aimed to explore the impact of objective complexity and Product of work task on user's interactive information searching behavior.

Method: The research population consisted of MSc students of Ferdowsi university of Mashhad enrolled in 2012-13 academic year. In 3 stages of sampling (random stratified, quota, and voluntary sampling), 30 cases were selected. Each of these cases searched 6 different types of simulated work tasks. Students’ Interactive Information searching behavior was measured by “loud thinking reports” and “log files”. Also, reliable questionnaire (Cronbach's alpha= 0.88) was applied to measure subjective complexity. Validity of tools was verified through Faculties of KIS at Ferdowsi university of Mashhad.

Results: By increasing level of objective complexity, users view more databases, search engines and web OPACs. Also they use more queries and select resources, visit and analyze more results and spend more time during search process. Totally, they feel less satisfaction and success. It was also found that most participants spend more time to search IR systems related to tasks including intellectual product. Also, they iterate queries, use more search facilities, view, analyze and select more search results and resources. At the end, in spite of more interaction, satisfaction and perception of search success were reported not favorable.

Conclusion: It is necessary to pay attention to work task characteristics in designing interactive and personalized IR systems. So, recommendations raised from this study are appropriate to improve and develop Interactive IR systems.

Background and Aim: Since anyone can freely share any kinds of information in the cyberspace almost without authenticity, validation information seems important. This paper examines the concept of credibility and describes and analyzes some well-known models for the evaluation of the Web credibility.
Methods: This research is a review in terms of research methodology and theoretical in terms of the goal. Data collection was using documentary method.
Results: The assessment of known models of Web Credibility including prominence-interpretation theory of Fogg, Wathen and Burkell’s model for how users judge the credibility of on-line information, Hilligoss and Rieh’s unifying framework of credibility, Sundar’s MAIN model, Metzger’s dual processing model of credibility assessment, Lucassen et al.’s revised 3S-model of credibility, and Choi new framework for web credibility showed that the systematic concept of the connection between credit key dimensions and criteria that can be used to assess the credibility of the Web exists in none of these models other than Choi and thus the templates and the theories have limited explanatory power for a comprehensive interpretation of findings of experimental studies.
Conclusion: Due to lack of imperical testing of these theoretical frameworks through standard tools on a large scale, no one was empirically supported. Thus, it is necessary to examine these frameworks empirically to improve their validity with an experimental basis.

Background and Aim: The aim of this study was to measure the overlap of 4 local Persian search engines of Parsijoo, Yooz, Parseek, and Rismoun and to compare the capabilities of these engines in covering indexable web.
Methods: This was an applied and evaluative research. To collect data, a keyword-based method was used. First, the selected keywords were entered into the search engines and then a sample was extracted of the retrieved records. Finally, based on the existence or absence of these records in the search engines, the necessary data were gathered. Accordingly to analyze the data, inferential statistical methods were used.
Results: The relative overlap of the Parseek compared to that of Parsijoo and Parsijoo's one compared to Yooz was 26 percent on average and Parseek had the most recall. Rismoun had not any common records with the other investigated search engines. Three search engines (Parseekc, Parsijoo and Yooz retrieved 27 common records out of 225 recalled records; there was a significant difference between the relative overlap of the 4 search engines. Also, on average, Parseel, Parsigoo, Yooz and Rismoun covered respectively 38, 31, 26, and 6 percent of the indexable web. There was a significant difference between the coverage of the 4 search engines.
Conclusion: It seems that each search engine has a different indexing policy, and users need to search for more than one search engine to get comprehensive information about an issue. It can be predicted that by foraging in two search engines, Parseek and Parsijoo, one may access 70 percent of the indexable web.

Purpose: the aim was to identify users' search strategies and the rate of using search strategies on the web.

Method: It is a practical survey. The statistical population included all the postgraduate students in the first semester at Ferdowsi University of Mashhad. 95 students were selected by stratified random sampling method. To gather the data, log files were used.

Findings: 12 search strategies were identified which was divided into 5 general categories. Iterative evaluation strategy in another tab was a new form of evaluation strategy of results. Among all, starting search strategies were the most commonly used category which were repeated 397 times, and the search results evaluation strategies were ranked afterward, with 321 replications. The category of Simultaneous multiple resource access strategies, with 77 repetitions, were also the least used strategies, but in particular, the recurring exploration strategy, with 21 repetitions, was the least applicable strategy. Conducting correlation test between strategies showed that some of Pearson's correlation coefficients were significant. The strongest relationship was between the starting search strategies and the search result evaluation strategies with a 0.591 correlation coefficient.

Discussion: The results showed that the majority of students used traditional and simple strategies, such as the formulation of search terms strategy and the iterative result evaluation strategy, and they used more complex strategies in few cases. These results showed that the students need to be trained in using strategies.

Background and Aim: Under the influence of various factors, people use different methods and methods to obtain information and express different information behaviors. These behaviors have been introduced in the form of patterns and models of information retrieval by information science experts in recent decades, which can be used in various fields. One of these areas that almost all people are directly or indirectly involved in is the field of treatment and medicine.   
Methods: This paper whit quasi-experimental examines the Analysis of information behavior of psychotherapists in the process of diagnosing and treating mental disorders based on the Kuhlthau information search process model. The population of this study is psychologists and psychiatrists with more than two years of treatment history. The sample selected from this group also includes 30 therapists who entered the competition through a public call as a top therapist using a simple sampling method. 
Results: The findings show that the sequence of therapists' movements is in accordance with Kuhlthau's opinion and they perform a repetitive movement in the diagnosis and treatment process, but the level of presence of therapists (time spent) differs at different stages from the model considered by Kuhlthau. The findings also showed that variables such as treatment history, field of study, and gender could influence the behavior of therapists. On the other hand, the relationship between the information of the therapists' information behavior and variables such as information literacy, state anxiety and trait, specialized knowledge and self-assessment of therapists was significantly evaluated.    
Conclusion: The information behavior that a treatment specialist performs in his or her treatment process can be analyzed according to the Kuhlthau model.
