I'm with Josh and Andrew. _If_ the audio is made from the same edition as ours, it's just a new format of that number. In some previous cases, the producer of the computer-read file claimed copyright, and that's why Greg gave them new numbers, because we couldn't post both copyrighted and PD content under the same number, even though it was made from the same source text. We also said we'd replace them when the technology improved.
If we don't know that the audio is from the same edition, then it should get a new number.
Sounds very sensible. In the case of all the Librivox projects I've been involved with, they've definitely been based on specific PG texts -- see http://librivox.org/forum/viewtopic.php?t=376 for an example. Librivox also explicity releases all the material it records back into the public domain, rather than retaining any rights over it. -- Jon Ingram
