OK, here's is where it gets wierd.
I checked out a Barnes & Noble, for completeness' sake. They hardly had a bible section, though the store was at least as big as the Books-a-Million I visited. (To be fair, a large section was taken up by a coffee shop.) The only Catholic bible they had was an RSV Catholic Edition (how ironic), and they had a spread of NIV and NLT and KJV and NKJV. That was about it. Clearly their heart was not in their religion section.
Before that, however, I visited the Potomac Adventist Book & Health Food Store. This is a "big box" store for SDAs, complete with a bronze statue of Jesus washing Peter's feet on the sidewalk out front. As you might guess, they have a HUGE bible section. They have LOTS of KJV editions, and NKJV, and all the other big commercial versions (though they don't push the NIV as much). But they also have all the traditional modern "liberal" translations (except maybe the NAB, now that I think about it). JB, NJB, Goodspeed, Moffatt, NRSV, REB (disguised as the Oxford Annotated Bible). They had the KJV apocrypha; they had the NASB; they had Lamsa's Peshitta; they had the JPS Tanakh; and they had a slew of parallel and bog-literal versions I'd never heard of.
So here we are at a conservative Christian bookstore, and it's the only place (other than a trip downtown to the shrine or the National Cathedral) to get the translations favored by liberals. THe irony is thundering.
