A recent announcement posted by Jim Anderson to the Yahoo Pali grammar list:
I'd like to recommend the following website for those who do not already know about it:
Ancient Buddhist Texts
Anandajoti Bhikkhu seeems to be the main one behind it or at least the main contributor. You'll find, for example, a comparative edition of the Dhammapada which shows side by side 4 different versions (Paa.li, Patna, Gandhaarii, Udaanavarga). There is also a revised edition (with a translation) in progress of a grammar based on the Padama~njarii by Ven. Devamitta of Molligoda (first published in 1922). The new work is entitled Navapadama~njarii. The website has a lot of material that will be of interest to students and scholars of Pali texts and translations.
