Due to the diligent work of Ven Khinabija at Bodhinyana, we now have the reference numbers for the widely-used Wisdom Publications editions of the Digha and Majjhima Nikayas embedded in our Pali text files. The DN numbers are in fact the same at the section numbers of the old PTS edition, and are widely found in our DN translations; and many of the MN translations also use these numbers, which were introduced by Bhikkhu Bodhi.
So now if you are reading one of these editions you can easily refer to the relevant section of the Pali text.
To see the numbers, as with all reference details on SC, open the sidebar and click “Textual Information”.
