I had previously looked at Netlibrary - in relation to ebook subscriptions, and had also heard of Overdrive.
Checking out Project Gutenberg's audio ebook collection, I had a listen to Sherlock Holmes (with an English voice thankfully). I feel they need the old fashioned chapters etc to let you know where you are, found this with talking books onMP3 where the whole disc is one long track with no breaks.
I'm 'watching' Bolinda's download developments.
Like the digital downloads from the view - no scratched discs and chewed tapes!
