The present study was conducted with the aim of understanding the online information-Seeking Process(ISP) among M.L.S students of libiary and information sciences at the state universities of Tehran. 36 students’ demographic features, preliminary knowledge and field of interests in web searching were identified using a questionnaire. Based on obtained results, 4 search scenarios in scientific, news and entertainment areas were designed and submitted to students. At the end of their search process, the participants were interviewed and asked 4 questions (3 close-ended and one open-ended). Using Track4Win Software Package, all search actions of the participants were recorded in Access Microsoft databases. Using Log Analysis method, and basing Marchionini’s ISP model, it was revealed that the participants go through the following stages during their information seeking process:35.63 percent in examin results, 27.42 percent in formulating and executing query. 17.33 percent in selecting source, 14.99 percent in extracting information, 2.82 percent in defining problem and 1.78 percent in reflecting/stopping.

The present study is to evaluate cataloguing consistency in Tehran’s academic and research libraries compared to that in the National Library of Iran. In order to limit the library collections, the subject category of “Iran logy” has been selected out of 12 relevant academic and research libraries. Using content analysis and survey methods, the data of the library catalogs from 1983 up to 1997 were noted down on specil sheets and then they calculated and analysed based on their main entries, subject headings, and classification codes. Data was analysed using statistical tables as well as Hooper formula. The findings of the preset study indicate that in 66.6% of libraries there is less than 50% inconsistency in main entries, whereas in 33.3% of them the inconsistency rate is between 65.5% and 87/5% In terms of subject headings, in 75% of libraries the inconsistency rate is between 60% and 85%. In 91.5% of libraries there is more than 50% inconsistency in classification. The most inconsistency rate of main entry belongs to the library of Danesh Pajouh and the least one belongs to the library of Humanties Research Center. The most inconsistency rate of subject headings belongs to the Art Faculty library and the least one belongs to the Humanities Research Center; whereas the most inconsistency rate in classification belongs to the International Study Center library and the least one is for the Parliament Library. The findings also indicate that, in terms of DDC Classification, the most inconsistency rate of main entries belong to the class of literature, the most one in subject headings and classification belong to the class of Philosophy. Summing up the findings, we can find that the total inconsistency rate in classification(73.37%) is more than the rate of subject headings(71 %) which, in turn, is more than the rate of main entry(50.8%).

The Creation of full-text retrieval databases, especially electronic journals, has been of great advantage for scientific communities. However, there are different factors, such as limited bandwidth and crowded networks, which affect the optimum usage of the systems. Verifying the relationship between requests and successful downloads, the present study tries to investigate the accessibility of the Science Direct’s (Elsevier) electronic papers at Tehran University and to highlight the impact of undesired factors on optimum usage.

In this study, the impact factor of the cited dissertations have been measured in the US dissertations, being defended during 1978-2001 in Tehran public universities. To achieve the objectives of the study, citation analysis method was applied. The findings indicate that the citations of 473 dissertations were mostly book-based (59.8%). Dissertations also were cited about 9.96%(i,293 citations) from total cited materials. The average number of citations was 28. As regards the impact factor of dissertations, the study showed that those of Iran Medical Science University had the highest impact factor in 1993, followed by Tarbiat Modarress University in 1993, and Then University of Tehran in 1999. Concerning the half life of cited dissertations, those belonging to University of Tehran had the highest half life(9 Years) in 2001, and those of Tarbiat Modarress University had the lowest half life(2 months) in 1992.

Though it has been essential to compile such a book for the library students, yet there are some points about it which can not be left unseen. Unfortunately most of our writers are used to rely on western references when compiling books on the history of civilization and other relevant subjects. While western writers, on the other hand, try to place themselves in the focus of all attention when writing about these subjects. Thus, they put non-western pepole, specially Muslems, on the outskirts. This very way of viewing the past and presednt history, has influenced the works of those writers who rely on western references. The present article trys to look for such influences in the fore-mentiond book.
