Citation analysis is one of the popular techniques of bibliometric study that aids scholars in the identification of core journals in their respective domains. The present study is based on
1399 citations used in the 10 doctoral theses of the library and information science department of the University of Calcutta, Mangalore University, Manipur University, Mizoram University, and Gauhati University that are deposited to Shodhganga from 2020. The purpose of this study is to determine the most favored information source, and year-wise distribution of citations as well
as to prepare a ranking list of core Journals in the library and information science based on the citation frequency of that journal. Data were gathered and analyzed based on pre-determined criteria.
Finally, the conclusion has been drawn from the data analyzed.
