If one site for audio books is good, two must be better.
Like Loudlit, PodioBooks is a site with books in MP3 format. Between the two sites, there’s a pretty extensive collection of titles that are in the public domain. Unfortunately, not everything’s there yet. I just tried to find the Scarlet Letter for our English teacher, but had no luck.
Still, the price is right and more books are being added on a regular basis. It’s worth taking a look.
