Logos is publishing a digital version of the Göttingen Septuagint: HERE.

The Septuagint is essential for studying and understanding both the Old and New Testaments and this is a very, very exciting development.

You can read more about this critical edition at Logos’ page as well as at the The International Organization for Septuagint and Cognate Studies website.
