Is there an eBook reader compatible Tripitaka?

You can find here some selected sutta translations from the Pali Canon, as translated by Thanissaro Bhikku to English, in the azw3, mobi, epub and pdf formats. With Kindle, please use the mobi format for best results.

The Full set of the scans of the PTS translations of the 4 Nikāyas and the Vinaya are available in zipped PDF files at: http://buddhadust.net/backmatter/indexes/idx_downloads.htm#pts_pdfs

This is the same collection as mentioned above as located at obo.genaud.net. That site has become obsolete due to our inability to update the site and has been replaced by buddhadust.net. This site also has the full set of PTS translations in html format. The new site has been completely converted to Unicode which makes use of the source files much easier.

If these files are wanted strictly for personal reading, the PDFs will just make it: they are not of the best quality scans. They were originally put together to assist in proofreading the html files. If what is wanted is a clear rendering for further distribution it would probably be better to take the source files of the html version and convert them directly with a tool like Calibre.

The site also contains all the Bhk. Bodhi translations made available to the public gratis; the translations of Bhk. Thanissaro; the Sister Upalavanna translations, the translations of the Majjhima of Lord Chalmers, the manuscript of Bhk. Nanamoli's translation of the Majjhima, and the individual sutta translations of a variety of lesser-known translators and the Pali text. All in html format. Translations are linked to each other and to the Pali. See the Sutta Index Page: http://buddhadust.net/backmatter/indexes/sutta/sutta_toc.htm which lists every single sutta with a short description. The PTS suttas have also mostly been unabridged in the html version.

As well as the suttas which are listed in this answer:

• There are translations from the Vinaya linked here on Access to Insight (many of the PDFs are commentaries rather than translations).

• This page (from 2005) of Access to Insight implies (though I don't know if that's true) that many of the Abhidhamma books haven't even been translated at all, let alone made available in eBook format. Still, there is at least A Manual of Abhidhamma, a commentary in PDF format. There are also translations of the Visuddhimagga (not sure whether that counts as tipitaka).

• Also:

  • There are many PDFs at http://static.sirimangalo.org/pdf/ including suttas, Pali grammars, texts from the vinaya, dhammapada, jataka, etc.

  • There's an eBook library at http://www.buddhistelibrary.org/en/index.php?lang=english (which may have some books not found elsewhere, in its Theravada Texts category).

  • These Pali Text Society Publications are suttas in PDF format (actually they're ZIP files with a PDF inside, I don't know whether you can unzip on the Kindle, or need to download and then unzip before copying to Kindle).

I am presuming you are looking for translations. There is the Buddha Jayanthi edition which has both Sinhala and Pali.
