For about 18 months now I have been working on a revision of The Great Chronicles of the Buddhas by Mingun Sayādaw, which tells nearly all that is known about the Buddhas and their disciples in the Theravāda tradition.
Mingun Sayādaw was the vissajjana who answered the questions at the 6th council, and was chosen for that work as he had memorised the whole Tipiṭaka, and the commentarial system that accompanies it.
The Great Chronicles of the Buddhas is truly a massive work, in my edition totalling nearly 3,000 pages, and has besides the stories, a lot of expository material as well. As Mingun Sayādaw combined the stories from different commentaries, as well as from the Mūla text, this is about as comprehensive a picture you could hope to get of the subject.
At present I am still working on getting the text ready, but the first section which tells the story of the Bodhisatta from his life as Sumedha, through all his meetings with the 24 Buddhas, up and till he himself attained Awakening. (The other lives, collected in the book called the Jātakas, are referred to throughout, but are not told in full here, of course. They can be found in a separate revised edition here.)
As this is an ongoing publication it is available only in html online at present. Eventually, when the whole document is ready, it will be published as PDF and EPUB as well. I have prepared a publication schedule, which can be found in the Preface to my Revised Edition, which also explains the changes that have been made in the present edition.
