It’s similar to the old Amplified Bible, which I like. But it uses, according to the preface, a modified text of the New Century Version. You may find some helpful resources in this one.
Somebody correct me here, but as I recall, the NCV was originally done by our brethren, and branched off after sold to a denominational publisher. Can’t remember if it’s a ERV or SEB branch.
Anyway, the strength of this will be the inline options. Rather than putting it in footnotes, most of it appears in brackets. Maybe a new format for a lazier generation? Dunno.
UPDATE (2010/July/30): The page for the version has changed, and the PDF has been removed and replaced with a nifty, but less navegable popup. If you’d like the PDF file, comment below with your email, and I’ll send it to you.
