The Indian International Journal of Buddhist Studies (IIJBS) is a peer-reviewed, scholarly journal dedicated to supporting the academic study of Buddhism in all its varieties. The Journal is published by the Bhikkhu Jagdish Kashyap Institute of Buddhist and Asian Studies and sponsored by the Aditya Shyam Trust, both of which were founded by Dr. A. K. Narain, late emeritus professor of Buddhist Studies at the University of Wisconsin, Madison, and Banaras Hindu University. Dr. Narain was the founding editor-in-chief of this Journal, its predecessor, the Indian Journal of Buddhist Studies, as well as the founding editor-in-chief of the Journal of the International Association of Buddhist Studies (JIABS) (1976-1986).
IIJBS is a New Series, starting in 1999-2000, in continuation of the Institute's earlier periodical, the Indian Journal of Buddhist Studies (IJBS, Vols. I to X, 1989-1998). It is published annually around Vaiśākha Purnimā (May-June).
