Will Ross has put together a superb bibliography for Septuagint research from a project for Currents in Biblical Research. He has organized it by categories and made it available on his website: LXX Bibliography (2012-).

I would highlight for our readers, here, several sections:

• 8: Wordlists, Lexicons & Grammars
• 14: The Language of the LXX
• 15: Translation Studies

You can also read about how, why, and where this project came from: An Absolutely Gigantic Septuagint Bibliography.

Many thanks to Will for sharing these efforts with the rest of us.
