Little contemporary scholarly attention has been directed towards the religious history of the early dge lugs school of Tibetan Buddhism. Most accounts of that period are derived from Tibetan sources dating from the post-1642 era of dge lugs dominance, notably the histories and biographies written by the Fifth Dalai Lama ngag dbang blo bzang rgya mtsho (1617-1682) and his regent sde srid sangs rgyas rgya mtsho (1679-1703). Derek F. Maher discusses the preliminary results of research he is currently conducting into one of the key Tibetan historical accounts that predates this period, the History of the Old and New bka’ gdams pa School by Paṇ chen bsod nams grags pa (1478-1554).
