With the recent developments of the Tyndale Commentaries and Zondervan NIVAC, there are only 6 titles left on the best list which are not on Logos: http://www.bestcommentaries.com/best.aspx I am not sure why the BST for the Old Testament by IVP hasn't made it to Logos yet, because we have the BST for the NT... this will perhaps come with time.
Still, this is amazing how much this list has been added to Logos even in two years.
