There is an electronic (PDF, HTML, ePub) version of the older (Some & Kheminda Theras) translation available at Visuddhimagga — digital (at the very bottom of the page; has some limitations, as it is OCR’d; the Pali footnotes might contain some mistakes, but the English text is good). Sadly, the Nyanatusita’s translation does not seem to be available electronically.
Hi there everyone! I just looked for a PDF of the “new” Vimuttimagga by Nyanatusita myself and I am very happy to report that there is now a free PDF version you can download on the official website here:
It seems that only the first book is available right now, but you will get almost 70% of the main text because the PDF ends at page 512 and at page 752 the appendices start.
