Mod — this post is on World Biblical Commentary offer at Koorong, and is not a place for religion debates.
59 Volumes of the WBC series in Libronix format.
Integrates into your Logos library if you have one.
Normally $350. I bought for $280 when it was 20% off.
It's currently 30% off.
It costs USD $690 direct from Logos. http://www.logos.com/product/8006/word-biblical-commentary
Edit:
These are high quality, academic, critical commentaries. Pick one up and have a read. If the best available evidence says "this part of the bible was made up and inserted after that section", that's how the text is treated and engaged. They're written by hardcore nerds (Christian and non-Christian) who have an insane grasp of their subject matter. Sure, "Koowrong" stocks a lot of rubbish, but these are well worth it.
Free Biblical Commentary is available in many places:

Not a bargain if it's free elsewhere
