Sekar publications of madras has come out with 2 volume publication of Thiru.Kudanthai N.Sethuraman's archaeological research papers. This author is well known for his path breaking research on cholas and pandiyas.
In one of the volumes, they talk about a number of research papers written by Sethuraman. Probably if we approach them, we can get more details.
I have also read many other books on tamilnadu history / archaeology by the same publishers
May I request one of you guys (Krupa ?) to call these publications and ask about their books on archaeology and research papers of sethuraman (unpublished) ? We can also enquire about Mylai and see if they have some papers...
(That reminds me - did any of you guys could get in touch with Mr.B.Venkatraman?)
