While browsing on jw.org, I suddenly spotted a new section under Digital Publications: Bible! As of today, the English edition of the softcover regular New World Translation of the Holy Scriptures (bi12-E) is available in one full 15 MB genuine PDF file, converted from the original MEPS-composed PostScript files! Take a look at it here: http://www.jw.org/index.html?option=QrYQCsVrGlVlYR
More languages coming soon (hopefully!)
