Librivox is a great project, it uses volunteers to read, edit, prooflisten and make available copyright-free audio books.

I've done several chapters in collaborative projects, and also several "solo" readings. My most popular (so far) have been:

• Stalky and Co. - Rudyard Kipling > 8,000 listeners
• A Man of Means - P. G. Wodehouse and C. H. Bovill > 1,500
  
• American Notes - Rudyard Kipling > 1,500

Compare that with just 750 downloads from Archive.org of my recording of the much better-known Just So Stories and you get a picture of the benefits of collaboration on a project like this!

I am just finishing Three Men and a Maid by PG Wodehouse and was really encouraged by the feedback on these recordings from Gustav evacuees (see Gustav, Librivox and Life).

In its way PodBible is another collaborative (over 300 volunteer readers and dozens of ongoing volunteer workers) reading the Bible first live over a long weekend, now podcasting the Bible a chapter a day or the whole Bible in a year, and soon to make individual books available in one hour chunks as an audio Bible you could download and put on CD or cassette for those with poor eyesight. The translation we used the CEV is designed for easy listening and is suitable for ESL listeners.

There is also a PodBible Facebook page where a different group of listeners can get a daily "fix" of the Bible.
