Regarding the increasing growth of the social web and its tools as a new ground to distribute research findings and scholar communications, there is a necessity for evaluation of the quality of scientific research, which was distributed through this media. This study aims to introduce altmetrics as a new solution for evaluation of the research impact in the social Web.
This study has been done based on an analytical and critical literature review. In the first part of the paper, altmetrics has been defined and then the related literature has been explored to identify the limitations and weaknesses of the traditional methods of research evaluation. In the next stage the indicators and tools of altmetrics have been explained. Moreover, the benefits, implications and limits of this method have been explained in more details. The final part of the paper includes a roadmap for further altmetrics research.
Findings: Altmetrics’ indicators which are based on the social web are being used as new alternative methods of evaluating the usefulness and the impact of articles and other types of research findings. These methods, which are becoming more popular, are useful to assess the impact of academic and nonacademic studies. The speed, simplicity and clarity of these indexes are among the reasons of the accreditation of this new approach. Finally, it will lead to the development and flourishing of these new scholar communications.
Altmetrics is a new method of assessing the impact and the distribution of academic and nonacademic studies and can be considered as an easy, appropriate and relevant way of research evaluation. This approach is still in its beginning stages and its development requires more detailed studies to examine the efficiency of alternative methods.

The aim of this study was citation and co-authorship analysis of Islam and Quran sciences researcher between years of 1993–2012.
The research method is survey. scientometrics rules such as Lutka’s and Bradford rules were used. Data were gathered from WOS database. HistCite™ software was utilized to build histography maps. “ UCINet” and “NetDraw” were used to draw co-authorships maps.
Findings: in general, 4535 records were published in this period. The distribution of the collaboration frequency of the authors follows the Lutka’s law, but distribution of Subject frequency of the core documents was not confirmed by Bradford’s rule. The average growth rate was 6.4%. The scientific structure of this domain on the base on of local citations and also global citations frequency showed that these maps consist of 9 clusters, also co-authorship maps consist of 2 main components.
The results showed that the collaboration between the authors is weak. Citation analysis showed that there is a significance correlation between the number of authors and the number of citations, also the collaboration rate of an author has a significant correlation with the number of documents published by that author.

The purpose of this study was to test Lotka’s law base on scientific publication productivity of Iranian scholars in the field of Library and Information Science (LIS).
The data were collected from the Iranian journals (2002-2013) and were sorted in Excel. Totally, 1994 articles published by 1470 authors during the above period. The authors’ frequencies were calculated based on the number of articles and regression was calculated using Excel.
Findings: Lotka’s Law was tested using the formula, the values of the exponent n and the constant c were computed.The values of n were calculated to be 2.12. Findings show that %63.26 authors published one work only.
The results show that Lotka's law did not confirm among Iranian LIS scholars.

The purpose the present is the citation and co-authorship analysis of the Islam and Quranic science researchers in “web of science” database and mapping the scientific structure of this domain between years of 1993–2012.
This research is applying and we use scientometric methods and some rules and procedures related to this domain,. HistCite™ software was utilized to mapping the structure of science, and considering of “Ucinet” software and its supplement package “NetDraw” the results showed that in this time interval,
The researchers of this field succeeded to produce 4535 records. Frequency distribution of the participation of the authors of this domain follows from Lotka rule, but objective frequency distribution of the core documents produced by the authors of this field was not confirmed by Bradford’s rule. Also, this domain had the average growth rate of 6.4% and at the end. The scientific structure of this domain on the base of the rate of local citations and also global citations was considered and mapped by using of HistCite™ software.
The results suggest that this domain composed of 9 clusters on the base of local and global citations,. The results show that the co-authorship of this field is weak. Citation analysis of the documents under consideration show that there is a positive Co-relation between the number of authors and the number of received citations and also the collaboration rate of an author have a positive relation with the number of documents published by that author.

This study uses ESI indicators and statistics database for comparative evaluation of scientific production of Iran, Turkey, Egypt and Pakistan during 2002- 2012. This study is a survey and is done scientometrics approaches. SPSS software used For analysis of findings. Toky and Pearson correlation test was performed. Study population was leader Islamic countries who indexed base of ESI information. Our findings show that the ranking of scientific production and citations of countries, respectively, was Turkey, Iran, Egypt and Pakistan. But the in the ranking based on the average citation rate per paper Iran after Turkey, Egypt and Pakistan was located. The average citation rate per paper of turkey in 11 fields of 22 fields was in the highest position and in the 2 fields was the lowest position among others. Iran in 1 field was in highest ranking and in 10 fields in lowest position. Turkey and Iran had the best and the worst performance, respectively. Hot papers in Iran (9), Turkey (7), Pakistan (5), Egypt (4), respectively. The subject areas cited for each of the countries, Turkey (22), Iran (20), Pakistan (19) and Egypt (16), respectively. In all countries between the number of scientific publications and citation rates significant positive correlation were observed. Survey showed among leader Islamic countries Iran’s growth of scientific production, was impressive, but no in growth rate of citations.

The aim of this research is to determine citation behavior of writers of M.Sc. theses in agriculture field, and to specify behavioral patterns,(informational language, and temporal) that are used by them.
This is a bibliometrics research (by use of citation analysis technique) that uses content analysis method. Statistical population of this research includes all of the present citations at reference section of Bu-Ali Sina University M.Sc. theses in agriculture field during years of 2001-2011(3370 citations). The required information was compiled by use of special cards, Citation analysis and library studies and defects were eliminated by visiting different websites and union catalogue of libraries of Bu-Ali Sina University. Afterwards, data was analyzed by descriptive statistics, and using SPSS19, Excel 2007.
Findings: Citation to native sources is more than foreign ones. Citations to Latin journals (69.15%) are more than Persian Journals (30.85%).
the study revealed that books and other print materials are prior in use. Hence, use of Internet is increasing.
