Below is a slideshow I created awhile ago and published here before. It basically features some of the best audio books available for teachers and students. I have done some updating to its content and republish it in this post. So if you are looking for some trusted websites where you can search for, find and even download audio books , the websites mentioned below will be of great help to you.
I have attached a review of almost every tool I included in this slideshow, clicking on any title will take you directly to the review page and from there you can access the tool page itself. You are free to download and use this slideshow for no commercial purposes. Just keep in mind that when using it elsewhere, you do have to pay credit back to Educational Technology and Mobile Learning.
