Very very interesting bibliography doc. From Thyagarajaswamy Satavarshikotsava Sanchika, 1947. There are quite a few interesting articles in that magazine, including Bengaluru Nagaratnamma's etc etc...
Any one knows if another effort has been made after 1947 to record the bibliography on Sri Tyagaraja (after 1947) till date? Any one? If yes, pls send an email to contact at maganti dot org
Thanks in advance
Oh - here is the link for the bibliography
