What do you call a book on tape when it's an mp3?

I love free music. I love free anything really, but free music is really enjoyable. Free movies are also nice, though I try to take only those that are in the public domain, and therefore do not fall under copyright infringement.

What I love even more is the new awesomeness that I have discovered which is audiobooks. I first got the idea from the Fairfax County Public Library. They loan out electronic copies of their books on tape, though in a specific program which prohibits burning a CD from them or uploading them to your ipod or other portable media. This presented a problem, as I had hoped to listen to the books while at work, and taking my home computer back and forth with me to the office is a ludicrous, though comic, idea.

And so I looked further. There is a wide world of books on tape/mp3 that I had hitherto unexplored. Today was spent with a job I would normally have hated, but passed quickly and nicely with Douglas Adams’ “Hitchhiker’s Guide to the Galaxy”. While talking of this to a coworker at lunch, she told me of a website that has mp3s of public domain books, things like Jane Austen, and confessed to having spent much of last week listening to Pride and Prejudice and to Emma. Two of my all time favs! She hasn’t yet sent me the link, but will soon I hope so that I too may enjoy the public domain-y books and thereby avoid the feeling of guilt that I have when “stealing” mp3s. (Though really, I own every book I have so far “stolen” so the author or the author’s estate has already made their money from me, and what I am taking is simply a shorter version of reading the book myself into a tape recorder. So there.)
