Sukumar Ranjan Das is an Indian author and scholar. Publicly available information about him is limited, and neither his dates of birth and death nor a detailed biographical record has been clearly documented. One work by him is held in the collection, namely Chitta Ranjan. Judging from the title and the author's research background, the book likely deals with Indian history and culture and may be connected with the modern Indian political figure Chitta Ranjan Das. Das's writing tends toward the study of historical figures and national culture, addressing readers interested in modern Indian history and intellectual life. Because relevant sources are scarce, his academic lineage, institutional affiliations and wider influence cannot yet be confirmed. On the evidence available, he is a scholar-author whose writing centres on Indian history and culture; his output is small, but his choice of subjects shows a sustained interest in his country's historical figures and cultural traditions.
