I have never given audio books much thought, but the posts in this thread ignited an interest. I tend to get migraines when I strain my eyes too much; audio books seem to be a possible solution. I am not quite sure what themes are available, meaning story books, scientific books, magazines, latest news... Where does a rookie start in this new 'unfamiliar frontier' to find out what types of audio books are available? Is a set of headphones all that is needed to access an audio book?
