The data were analyzed to observe the year wise pattern of growth of output with citations per publication (CPP), most prolific countries, institutions, and authors. It also identified the distribution of citations with highly cited papers and further source titles were used to establish the linkage between research results. Analyzing authors, institutions and country of the publications, citations complete count methodology was followed. The United States, the United Kingdom, and Iran were found to be the leading contributors to the field, and the pattern of growth is undulating. The journal articles (228) were scattered among 80 source titles, and it connotes that on an average, approximately three articles were produced by each source title. Moreover, a detailed and comprehensive content analysis of all the publications of clusters formed in co-citation and bibliographic coupling networks was employed to get the in-depth knowledge of the trend in concerning literature.
