How was the Buddha Jayanti edition of the Tripitaka derived? I've read that the three Theravada countries Sri Lanka, Thailand and Myanmar all three have their own version of the Tripitaka.
I've also read that in 1956 they held the Sixth Buddhist convention with the goal of creating one standard edition of the Tripitaka, called the Buddha Jayanti-edition. The Dutch version of the Wikipedia page on the Pali canon claims that


  The Buddha Jayanti-Edition, however, was composed by the most distinguished monks of the three main Buddhist countries and is considered the most correct version 
  (original wiki page here, English translation here)


I was wondering if this is true. How do they know that the Buddha Jayanti-edition is the most correct version? What exactly are the differences between the 3 Tipitaka versions and how did the monks resolve them?
I have some experience comparing the BJT Pali with the Pali Text published by the Pali Text Society and the version found on the CSCD. I have read and proofed the BJT of numerous suttas throughout the Sutta Pitaka, the complete Anguttara Nikaya, and the first two volumes and many other suttas from the Samyutta Nikaya. On the whole the BJT and the PTS agree with some spelling differences and an occasional insignificant difference in text matter. Both have errors. The BJT has the advantage in that for the most part it has unabridged the text. (Trying to figure out which previous phrase was intended by '...pe...' is no easy matter!) The BJT has errors resulting from copy and paste where sections are repeated with a change but where the change was not made. The Pali Text Society text is, as far as I am concerned, the most authoritative simply because the compilers consulted numerous manuscripts for its compilation. The CSCD is also commendable for that reason, but it has not got the advantage of eliminating all the abridgments.

This does not cover the complete scope of your question, but hopefully it will chip away around the edges. To best see what I have done with the Pali texts and the PTS translations visit the 'What's New?' page at:

I cannot claim that this work is error free as it is being done with excessive haste, but it should provide a strong platform for a future completely unabridged pali and translation of the Sutta Pitaka. It should also be helpful to beginning translators as the text is broken up at the original line breaks which helps to overcome the despair inspired by a huge block of Pali. Translations are linked to the other available free translations.
