Main Article Content
The aim of the present study is to analyze the authorship pattern and collaboration trends in the Nature Nanotechnology during the first ten years period. Bibliographic records of the source journal are obtained from the Web of Science core collection. A total of 2060 articles published in the first ten years and those are analyzed in terms of authorship pattern. Various bibliometric tools such as collaborative co-efficient, degree of collaboration and co-authorship index are employed. Further, applicability of Lotka’s law is tested. The results show that 73% of total publications were collaborative in nature. The collaboration
co-efficient has been arrived at 0.58 and collaboration index is calculated to 6.76 for the first ten years. The value of Co-Authorship Index (CAI) for co-authored publications with more than three authors shows an increasing trend from first five year block period to another while for publications with few authors (<3), it
reveals a declining trend.
