Darwin's "Origin of Species" free audio download

Darwin's "On the Origin of Species by Means of Natural Selection" is now available free to download, copy, and share. It's unabridged and over twenty-four hours long! It can be found at Librivox. via BoingBoing

I just took a look at Librivox's web page and although they are rather light on science, did find a few gems for the science-minded:

• For the environmentalist: Walden by Henry David Thoreau (also Nature, Smoke, On the Duty of Civil Disobedience, and Woof of the Sun)
• For the chemist: Familiar Letters on Chemistry by Justus Liebig (don't miss Letter 14 - Nature and Effects of Manures) (in progress)
  
• For the physicist: Relativity: The Special and General Theory by Albert Einstein (Check out the understated Part III: Considerations on the Universe as a Whole) (in progress)
  
• For the child in all of us: The Fairy-Land of Science by Arabella B. Buckley (Arabella Buckley worked as secretary to Charles Lyell -- Darwin's mentor -- and in later years lectured and wrote about science and evolution. Although written for children, it has solid foundations in scientific thought. I haven't read it but it looks awesome. There are even two chapters on bees, my second favorite social insect!) (in progress)
  
• For the conservationist (with a sense of humor): A Modest Proposal by Jonathan Swift
• For the philosopher: Has a Frog a Soul? by Thomas H. Huxley (also known as Darwin's bulldog)
