Yesterday I happened on a good Septuagint blog, LXXI (“Just another guy trying to track with ‘the Seventy'”). There are helpful and enjoyable Septuagint posts throughout. Most helpful to me so far has been LXXI’s reviews of three of the best-known Septuagint introductions, which you can read here.
Words on the Word 
Thanks for the shout-out, Abram. I look forward to clicking through your blog in the coming days. Speaking of Septuagint blogs, be sure to check out John Meade’s LXX Studies: http://septuagintstudies.wordpress.com/
You are welcome, Brian, and thanks for the link!
