The SBLGNT is edited by Michael W. Holmes, who utilized a wide range of printed editions, all the major critical apparatuses, and the latest technical resources and manuscript discoveries as he established the text. The result is a critically edited text that differs from the Nestle-Aland/United Bible Societies text in more than 540 variation units.
Students, teachers, pastors, and interested laypersons can use the SBLGNT right now for research, writing, and study—at no cost.This Kindle file has great formatting, and the Greek letters look perfect. Now I have one less book that I have to physically bring with me to a debate. Many thanks to Michael W. Holmes for the work he put into this.
I got this picture from Denny Burk's webpage. It nicely shows the sort of formatting and text you can expect from this GNT. However, I did load this onto my Kindle app for the iPhone, and it has some formatting problems in that version. Once again, you can download it for Kindle by clicking here.
