It can be read online for free (under a Creative Commons Attribution/Share-Alike license), and has also been published in French, Italian, and Portuguese.

And if you’re looking for a faster references dealing only with photographic copyright, be sure to check out the American Society of Media Photographer’s excellent copyright law FAQ, as well as this short and sweet post written by the Professional Photographers of America.
