The purpose of this study is to identify the compatibility of the inborn leadership style of the librarians to their situational leadership style using Fiedler’s Contingency Theory of Leadership; to find how the changes in situational variables affect one another; to investigate the degree of correlation between situational variables and LPC score obtained by the librarians. The head of the libraries of Dr. V. S. Krishna Library of Andhra University, Knowledge Resource Center of GITAM University, Osmania University Library and Ramesh Mohan Library of The English and Foreign Language University have been selected using purposive sampling technique. In order to investigate the leadership style of the library officials, survey and interview method was adopted. The result of the study shows that all the librarians are identically inherited relationship-oriented leaders but they are task oriented leaders in the regular situations of the library. The evidence of both positive and negative covariance has been found where power position seems to be playing the pessimistic role. It can also be found that the relationship between task structure and leader member relationship is the strongest whereas that of LPC scale and task structure is lowest. The originality of the study lies in the determination of leadership style and situational favourableness in the practical situation.
