No, the NLS does its own in-house recordings with a stable of professional narrators who have some crossover with the commercial audiobook world. They're generally good quality productions. (It drives me a little nuts to see the NLS spending all this money and resources to duplicate books already recorded commercially, just because that's what they have to do to take advantage of the alternate formats copyright loophole.) The Jennings is the commercial audio production. Random House, I think. It's what I turned to when the NLS narrator just couldn't cut it anymore for The Dark Is Rising. The Jennings is quite good, I think -- he does a good Cornwall, and a very muddy-mouthed Buckinghamshire. And his Merriman is gruff and remote and a little frightening, but wonderful all the same. As he should be.
