Abstract

This paper presents a Bibliometric analysis of the authorship pattern in the field of Hepatitis C covered in the Journal “Gastroenterology”. The literature covered for the period 2006-2010 in the Journal was considered. Citation Analysis was used for this study. Records covered in the citation from the year 1908 to 2010 were identified. This study was aimed to examine authorship pattern in the field of Hepatitis C. There were 137 articles from the source journal during the study period and these articles had a total of 5132 cited items. Hence, only authorship pattern in the field of Hepatitis C is discussed in this paper. 93.26% of the total contributions represent collaborative research. The degree of collaboration has been arrived at 0.93 during the study period. The value of Co-Authorship Index (CAI) for single author paper shows a declining trend from one block year period to another block. On the other hand, for multi authored papers, the Co-Authorship Index reveals an increasing trend.
