2005 Thai edition |
But now by coincidence I stumbled on the original 1969 doctoral thesis, which was the basis for the book. The University of Oxford, where Tej Bunnag studied and graduated, had made the original version an open access item, so it can now be downloaded and read easily by everyone. Not sure whether I'll find the time to actually check what changes were done between the thesis and the book version, in fact more interesting would be any changes which were done for the Thai edition.
