Abstract
Background and Aim: One of the main criteria in scientometric evaluation of the medical sciences universities is the number of published articles in the journals that have high Impact Factor (IF). The IF is an indicator to evaluate the journals. Many shortcomings of IF were revealed. This review aims to bring out the challenges of IF and the related solutions of them.
Materials and Methods: Required literatures for this review were collected by searching in related databases such as Web of Science (WOS), Scopus, Google Scholar, and also Google search engine as well as SIGMetrics Discussion Group. Determined search strategy limits search to exact phrase and synonyms. Results selected considering relevancy. The review covers the literatures published between 1972- 2007.
Results: We found at least 18 shortcomings of IF which reduce the efficacy of this indicator. In addition, they stated some solutions versus the shortcomings however, there is no suggested resolution for some of the shortcomings.
Conclusions: Considering the shortcoming of IF, however it could not be ignored because of its accessibility and ease of use. Solely, IF cannot solve the researchers' problem of qualified journal selection. Such solution needs awareness about IF challenges. Readers' judgments and journal clubs are valuable qualitative ways, which can help IF in the evaluation of journals.

Abstract
Background and Aim: Citation could be considered as basis of scientific researches. Each researcher will use citation to prove his scientific findings either to be in correspondence with truth or to familiarize readers with more references. Maintenance and continuation of informational link by citation is essential. Theses are not exceptional for this subject. This study was done to review the accuracy of cited articles of specialized theses (Tehran University of Medical Sciences in 1386) and the rate of correspondence with Vancouver style.
Materials and Methods: Citation analysis is used as study approach. By systematic sampling and Morgan table 357 cited articles were selected to review for accuracy of citation and their correspondence with Vancouver style. Six studied factors are as following: Name of author(s), title of article, title of journal, year of Publishing, volume number, number of pages. Citation errors are divided in to two main groups: 1-Minor errors 2-Major errors. Method of sampling is direct observation. Data was entered in a check list, based on Taylor division. SPSS(11.0) software was used to analysis.
Results: Out of all 357 reviewed cited articles, totally 111.4% citation errors were observed and only 136 (38.09%) of citations had no error and 221(62%) citations had errors. 9.8% of citations fully corresponded with Vancouver style.
Discussion and Conclusions: Main reasons of dissatisfying results of citation errors and rate of correspondence with Vancouver style are as follows: Student's unawareness of importance of scientific researches consistence Laxity of students about citification produce, inaccessibility to original references and copy of other sources. Teacher's less emphasis on accuracy of citation, carelessness of educational universities about accuracy of citation in thesis, not use of experts and specialized librarians for consultation, being not familiar with reference management software.

Abstract
Background and Aim: Using Hirsch index as an important tool to describe the scientific outputs of researchers has caused some authors to increase their self-imposed parameters, increase, citing themselves. Therefore it is necessary to consider the effect of self-citation on Hirsch index for every author to have better measuring on the quality of researchers scientific production.
Materials and Methods: This research is descriptive method of citation analysis in general and specifically self-citation analysis. The study, are Iranian prolific authors in the field of medicine that have at least 30 documents indexed in Web of Science database between 2004 to 2006. Citations following up was studied till December 2010 Results was analysis using Excel software version 2007.
Results: The average self-citation observed between prolific authors in medical field was 25/89 percent. Hirsch index for 30/77 percent of authors had changed considerably. The authors rating scheme based on Hirsch index was done after removing self - citation so that 38/46 percent of authors decreased to lower level.
Conclusion: Considering that 10 to 30 percent of self-citation can be normal and justified, the status of self-citatin of Iranian prolific authors in medical field is desirable. Also, lower rates of self - citation of these authors doesnot affect Hirsch index.

Abstract
Background and Aim: Self-citation, as one of the limitations of citation analysis, unusually affects the ranking of journals. This study aims to evaluate the degree of relationship between self-citation and immediacy index correlation of Iranian medical journals indexed in Scopus Citation Index between 2005 and 2009.
Materials and Methods: The method of the study is survey-descriptive in which citation analysis is used. The study included all Iran-based English medical journals indexed in Scopus database up to May 2009. The control list was prepared and its validity was confirmed. Data were collected by referring to Scopus website and publication review resources, and analyzed by statistical software and appropriate methods.
Results: The findings showed that self-citation rate of journals was 29.64 percent, which comprised 14.43 percent of the total number of citations. There was a significant relationship (at the level of 0.01) between self-citation rate and immediacy index of journals (p = 0.591). Besides, Pearson correlation coefficient showed a significant relationship between the number of journals' articles and the journals' immediacy indexes excluding self-citation during the years of study.
Conclusion: Self-citation has a direct effect on journals' immediacy index that is, an increase in the rate of self-citation causes an artificial increase in the journals' immediacy index. On the other hand, immediacy index is affected by the number of journal articles. Therefore, the reduction or elimination of self-citation seems to be necessary for the journals and can put them in their right place.

Abstract
Background and Aim: Citation is one of the journals ranking factors. Self-Citation rates regarding journals `performance, especially in international databases, is important. The aim of this study is to examine the effect of Journal self-Citation on Impact Factor of Iranian English medical journals indexed in the Web of Science and Islamic World Science Citation Center.
Materials and Methods: The Impact Factor of 12 journals in WoS and 26 in ISC were studied during years 2006-2009 using citation analysis and Journal self-Citation. Self-Citation rate were calculated using cited journals and citing journals tables in ISC. Wilcoxon test and Mann-whiteny test were used for comparison of self-citation rate between two databases. In order to determine any correlation between journal self-citation and IF in WoS, Pearson test was used. In ISC, Spearman test was performed. For comparison of two correlations test, Covariance test was used.
Results: No significant difference between Journal self-citation rates in two databases was noted(p>0.05).There was a significant correlation between Journal self-citation and Impact Factor in WoS(p=0.007, r=0.64). The correlation was not statistically significant in ISC(p>0.05, rsp =0.23). There was not any significant difference between the relations of Journal self-citation and impact factor in two databases(p=0.526).
Conclusion: Attention to the Journal self-citation rates for comparison of Journal Impact Factor in WoS is more important than attention to the comparison of these journals between two Databases.

Abstract
Background
and Aim: Scientific journals are the most
major tools in disseminating research findings. With the increasing number and price of scientific journals, libraries
need to select journals. Citation analysis is a practical method in identifying
the best titles to be subscribed. This study was to identify core journals in
the field of dentistry using citation analysis.
Materials
and Methods: Two hundered and seventy six
documents including dentistry theses (241 titles) and faculty papers (35
titles) indexed in Science Citation Index (SCIE) were selected and their
references were extracted and evaluated using citation analysis methods. The
distribution frequency of journals confirmed the Bradford’s Law of Scattering
representing core dentistry journals.
Results:
Eleven thousand
twenty three references were totally extracted. Average reference per theses
and papers was 39/25 and 44/74, respectively. English journals and books were
the most frequent referred documents having 95% of total references approximately.
The most updated references were in English dated during 2001-2005 and
2006-2010. Using the Bradford’s Law, five journals were introduced as core
dentistry journals.
Conclusion: Selecting and subscribing core
journals leads into cost-effectiveness in libraries and plays an important role
in meeting user’s needs. While having
many challenges in accessing scientific resources, core journals selection and
subscription is an intelligent action
resulting in effective use of financial resources.

Abstract
Background and Aim: Indexing a country's scientific journals in international citation databases can lead to the promotion of its academic status and its participation in global knowledge production. This study aimed to assess the conformity of Iranian English-language medical journals’ citations with the objective criteria of journals in the selected databases.
Materials and Methods: This was a descriptive, evaluative research. The study population included 52 Iranian English-language medical journals that are not indexed in Web of Science, PubMed and Scopus databases and 465 articles in these issues, and about 11235 citations to the articles. The data have been collected by a checklist. For data analysis, Excel software was used.
Results: Some 88.5 percent of journals had a style for writing references; a style that has been observed by most of them. The rate of self-citation was low. Only 2.9 percent of citations were done in the year this study was performed. Journals with 87.2 percent had received the highest number of citations. The old citation time and the imbalance in the types of cited resources were the most important reasons of the weakness of the studied journals and of their not being indexed in the mentioned databases.
Conclusion: Providing valid styles for writing references and controlling the citations accurately should be put on the agenda of journals. The time of references must be newer, and there should be a relative balance in the types of referenced sources.

Abstract
Background and Aim: Scientific journals are known as one of the basic tools in knowledge development in today's world and have a special place in publication of the newest achievements of human knowledge and science. This study aimed to evaluate Iranian journals of medical sciences in Scopus database and determine their level in the world.
Materials and Methods: This is an analytical-descriptive study with Scientometrics approach. The research population includes all Iranian journals in the field of medicine which are indexed in Scopus database until 2016. We used SPSS and Excel software to analyze data and NodeXL to draw shapes and pictures.
Results: The findings show that the number of Iranian journals increased from 2 in 1999 to 78 in 2015. Also, 15 cities and 29 centers and universities have played a role in publishing those journals. Meanwhile, the findings show that Iranian indexed journals are at a lower level compared with those of the developed and industrial countries.
Conclusion: The most important reasons for Iranian journals' growth were "the policy of Scopus to increase scientific journals", "observance of standards and compliance with international fashion and standards of medical journals”, and the like. We concluded that Iranian journals compared with those of other countries are not at a good quality position and that it is essential to have an appropriate policy by the Ministry of Health and its subordinate Universities.

Abstract
Background and Aim: In this study, in order to increase the visibility of articles in Scopus journals of Tehran University of Medical Sciences (TUMS), selective dissemination of information (SDI) service was presented and its impact on some citation indices was investigated.
Materials and Methods: This is a semi-experimental study of two groups (pretest-posttest design with a control group). In this study, TUMS Scopus indexed journals (20 titles) were randomly divided into test and control groups and their citation indices were assessed. Then, the SDI services for test group journals were designed based on PubMed's Alert system and presented to the university's top researchers for one year. Finally, the citation indices of the journals of test and control groups were reassessed and compared. For data analysis, independent t-test, paired t-test and, covariance analysis were used.
Results: Comparison of mean citations as well as SJR, SNIP and CiteScore indices before and after the intervention showed no significant difference between the test and control groups. But the average CiteScore in both groups after the intervention was significantly higher than the average before the intervention.
Conclusion: The results showed that the provision of the aformentioned services in the time period defined in this study had no significant effect on the citation indices. However, the valuable experiences gained in this study will undoubtedly be applicable to future research as well as services to researchers, librarians, and journal managers.

Abstract
Background and aim: This study aimed to determine the position of Iran in terms of scientific publications in Immunology and Microbiology, and also to identify the general status of science production and the patterns of publishing in the world, the Middle East, and Iran, analyze Iran scientific collaboration with the Middle East and the world, and explore the relationship between these indicators.
Materials and Methods: The study population contained 30622 Middle Eastern publications in Immunology and Microbiology from 2009 to 2018. Positioning the countries and exploring the relations of indicators, the exploratory factor analysis, and the correlation matrix were conducted using Scival.
Results: According to the findings Iran, Turkey, and Saudi Arabia were among the most powerful countries in the region in terms of publication, citation, regional, international, and overall scientific collaboration. As for regional positioning, the citations had the highest weight comparing to other indicators. Iran have the first rank in the indices of scientific production and citations with 43.63% and 33.76% respectively, third rank in the regional cooperation index with 43.63%, second rank in the extra-regional cooperation index with 23.56%, and also second rank in the total cooperation index with 22.12%.
Conclusion: The indicators were strongly connected togather; however, the citations and international scientific collaborations displayed the strongest amongst others. Despite Iran’s prominent position in both fields, the quality of the publication was lower than the regional and global average. This identified the most powerful and weak countries in the region in regards to scientific capacities in Immunology and Microbiology. Moreover, it reckoned that there was a strong relation between citations and scientific production in contrast with others.
