2. Authorship trend and collaborative research are important facets of Informetrics / Bibliometrics / Scientometric Studies.
The authorship pattern, one of prime aspects of citation analysis mainly deals with the kinds of authors, nature, degree of collaborations, bibliographic coupling, co-occurrence, co-citation among them and collaborative trends of authors.
Twentieth century has seen collaborative research trend among scientists working in groups within and across the geographic boundaries of a country, which enhanced the ability of scientists to put in their intellect in their respective domain of specialization.
Collaboration is inevitable in natural sciences and multidisciplinary areas to making significant advances and breakthroughs.

3. OBJECTIVES OF THE STUDY
The main objectives framed for the purpose of the study are
To identify the most productive authors based on Publications from Bharathidasan University.
To identify the most productive authors based on Citations

To identify the co-authorship pattern.
To identify the bibliographic coupling of authors.
To examines impact of Individual publications citations on University publications productivity, citations and H-index, Average Citation per Article.
To know the strength of cited references.
To identify the co-occurrence of authors.

4. METHODOLOGY
The study entitled "Authorship and Citation pattern of Faculty in Bharathidasan University” is a case study encompassing records output from Science Citation Index (SCI) available online (Web of Science).
The growth rate of output in terms of both at absolute level and relative level are analysed from 1989 to 2016.
The authorship pattern and author productivity are examined to identify the pattern of research contribution of Bharathidasan University.
Further, an attempt is made to measure the performance of researchers and citations pattern The study is mainly exploratory in nature in identifying research output of Bharathidasan University and it is also analytical in nature in strengthening the empirical validity due to application of suitable statistical calculations.

5. Citation
A "citation" is the way you tell your readers that certain material in your work came from another source.
It also gives your readers the information necessary to find that source again, including: information about the author. the title of the work.
An author is likely to be most aware of the work of Other scientists’ work may come to the author’s attention as a result of their discoveries, their leadership in the scientific community, Citation Analysis or their activities in the world of the world of politics control verse.

7. H-index
This field displays the h-index count and is based on a list of publications ranked in descending order by the Times Cited count.
The h-index is indicated by an orange horizontal line going through the Year / Total Year columns.
The number of items above this line, which is "h" have at least "h" citations. For example, an h-index of 20 means there are 20 items that have 20 citations or more.
This metric is useful because it discounts the disproportionate weight of highly cited papers or papers that have not yet been cited.

9. Co-authorship
Co-authorship networks are an important class of social networks and have been used extensively to determine the structure of scientific collaborations and the status of individual researchers.
Although some-what similar to the much studied citation networks in the scientific literature (Garfield, 1979), co-authorship implies a much stronger social bond than citation.
Citations can occur without the authors knowing each other and can span across time.
Co-authorship implies a temporal and collegial relationship that places it more squarely in the realm of social network analysis.

11. Bibliographic coupling
Bibliographic coupling, like Co-citation, is a similarity measure that uses citation analysis to establish a similarity relationship between documents.
Bibliographic coupling occurs when two works reference a common third work in their bibliographies.
Bibliographic coupling links to papers that cite the same articles, so that if papers A and B both cite paper C, they may be said to be related, even though they don't  directly cite each other.
The more papers they been citing, the stronger their relationship is Bibliographic coupling occurs when two works reference a common third work in their bibliographies.

13. Co-citation
Co-citation and co-occurrence are an alternative to traditional link building for SEO.
While definitions vary, co-citation happens when website A links to websites B and C.
In this scenario, websites B and C are said to be related through co-citation because they both are linked from website A. Co-occurrence refers to the text before and after a hyperlink.

15. CONCLUSION
The study found that one third of publication published out of 3442 publication by top ten authors from Bharathidasan university.
The study found that the top ten authors received 50% of total citation score out of 4020 authors .
The study found that the minimum number of publications contributed by Associate professor level people. Due to the associate professors are promoted as professors and assistant professor not promoted as Associate Professor level.
Faculty should be publish the paper in Open Access Journals publications and should be encouraged by the university authority and University Grant Commission.
Scientometric data provide precise and accurate observations.
During 36 years period global contributions in terms of number of publications is significant and average citations per article is not enough and should be strength the citations and h-index.
The records available in Web of Science database reveal a large number, it is important that the Web of Science covers only the peer-reviewed journals.
