When I started to listen to audiobooks, I used a portable cassette player. You could get cassette audiobooks at local libraries. Most libraries now have gone to all CD audiobooks. I don't like the CD ones as much because the portable CD players are cumbersome to wear, skip and with CD's if you miss an important word or two, you can't rewind that small an amount like you can with cassettes. I listen to the CD ones in the vehicle and can occasionally find cassette audiobooks at library sales and garage sales. The portable cassette players are getting scarce too. You can find them cheap at garage sales or beg one on Freecycle.
Recently I got an MP3 player that I can download library audiobooks onto. The MP3 player weighs nothing and getting the audiobooks from the library is free. I've only done one so far as first had to figure out the player and download software (OverDrive).
Which book did I download? Watership Down by Richard Adams. I've read this book several times but listening gives it another dimension. The narrator speaks in various voices for each rabbit and it is just wonderful to listen to. Plus the "rabbit language" that you couldn't pronounce in the book is read to you. If you've never read the book or even if you have, sign onto your local library's website. In Maine, sign onto your library's website using your library card number, then go thru Minerva, search the title and download it. Maybe you can even go directly to Minerva, I haven't tried that. Downloading certain books depends on availability just as it would be a real book to be checked out. Fortunately Watership Down is an always available book. What could be better than that?
It's a great book too for youth to listen to. I think it would be fun for a 4-H rabbit club group to "book club" it and then discuss it at their meetings. They may even be able to find the Watership Down movie video that pretty much follows the book. Though as in most cases, there is much more to the story in reading the book than simply watching the movie.
