Septuagint LXX Project

http://septuaginta.net/

From the homepage:

Septuaginta LXX Project aims to produce an online edition of the Septuagint with a comprehensive critical apparatus, and a new English translation. We seek to collate all extant ancient manuscripts of the Septuagint and make them available at this website.

Septuaginta’s Goals:

1. A new critical text of the Septuagint that is as close as possible to the original text.
2. A comprehensive critical apparatus.
3. A new English translation for the Septuagint, Aquila, Symmachus, and Theodotion.
4. A PDF version of the Septuagint that will be made available for download.
