The paper presents the characteristics of the literature archieved in NASA ADS consortia on a topic ‘Geophysics’. The study shows that the highest (570) number of articles was published in the year 2009 which constitute 17.32% followed by lowest (311 articles) which is 9.45% was published in the year 2005. Highest number of articles contributed by single author followed by two authors. With regard to Degree of Collaboration (DC) was 0.73 during the period 2005–2012 which clearly depicts collaborative research trend. The Collaborative Index (CI = number of authors per paper: Lawani) was 0.26 whereas Collaborative Co-efficient (CC) was 0.48. USA contributed highest number of articles followed by UK and France; it may be due to infrasture available for basic and applied research among these countries which lead to highest number of research output.
