It wasn't very long ago that in order to learn a new language, you would have to either take a course at a school, buy a learning cd or cassette, or get a book from a bookstore or your local library. Most of those options required money, or at least some effort in tracking down a book. With the advent of podcasts though, learning a new language has never been as convenient and free as it is now.

Below, I've listed several websites where you can download podcasts in mp3 format for use on your mp3 player or to burn to a CD. Some of them also offer reading material to go along with the episodes. All of these podcasts are also available through iTunes. I recommend using whatever is easiest for you, but do consider when you might have free time to listen everyday. If you go running in the morning, or have a long commute, those are excellent times to fire up a lesson. Many of them are short, so even if you only have 10 minutes, you can get through most of an episode.

Obviously, there are many many more languages than what I have listed here. Do a search in iTunes podcast directory, or on Google or Yahoo, to find the language you are looking for.
