Arya (2) studied authorship pattern and collaborative research trends in the field of veterinary medicine based on the data collected from 'Indian Journal of Veterinary Medicine' published during the period 1999-2007. Thavamani & Velmurugan (3), studied the publication trends of scholarly papers in Annals of Library and Information Studies, through a bibliometric analysis of 310 contributions in the journal during the year 2002-2012. Thavamani (4), identified the growth and authorship pattern of productivity of articles of source journal "DESIDOC Journal of Library & Information Technology". It was observed from the study that the year 2008 was most participating year during the study period 2007-2011. Thavamani (5), analyzed the Malaysian Journal of Library and Information Science. A total of 279 research articles and 575 authors were examined by growth of contributions by year and volume, authorship patterns by year and volume, authorship patterns, author productivity, single and multi authored papers by year, authorship patterns by global, most prolific contributors and degree of collaboration.
Thavamani (6), studied of Collaborative Librarianship (CL) during the period of 2009-2014. A total of 223 research contributions and 343 authors were examined by growth of contributions by year and volume, authorship patterns by year and volume, growth of authors by year, authorship patterns, author productivity, authorship patterns by global, most prolific contributors and degree of collaboration. Thavamani (7), studied the authorship trend in the "Chinese Librarianship: an International Electronic Journal (CLIEJ)" during the period of 1996-2013. A total of 133 articles and 221 authors in the Journal were examined by year and volume to ascertain authorship patterns, author productivity, and degree of collaboration. Velmurugan & Radhakrishnan (8), conducted with 448 contributions published in the journal selected six years for a period between 2007 and 2012. Ta[section]kin & Aydinoglu (9), studied the bibliometric investigation of the NASA Astrobiology Institute (NAI) funded research that was published between 2008 and 2012.
The objectives of the present study are as follows:
* To identify the Contributions by Type of Documents, to trace Research Contributions by Year.
* To study Authorship Patterns, to trace Author's Productivity and to identify Most Prolific Authors and to trace Authorship patterns by Country.
* To identify affiliated Institution by authors and to identify degree of author collaboration.
The data was collected from the website (LiebertOpenAccess.com) of the Astrobiology. Seventy Two (72) issues from six (6) volumes from 2012 to 2017 have been selected for the study. All articles are source article published in the last six years (2012-2017) were recorded in a separate white sheet and results were entered in Microsoft Excel. Statistical Package for Social Sciences (SPSS) was used for the analysis. These data were organized, calculated, tabulated, analyzed, and presented by using simple arithmetic and statistical methods in order to provide analysis.
