hello everyone

[A. G. Maisey]

Naploeon, you say :-

"--- study of the keris---"

this is an enormous field that needs several lifetimes to achieve anything like a comprehensive base of knowledge --- thus most of us settle for something a little less than comprehensive.

All the recommendations of the people who have already responded to you, I agree with, however, I would suggest that you might like to consider what it is that you find most interesting about the keris at this point in time, and then perhaps we could tailor our recommendations to help satisfy your quest for knowledge.
