Information on Native American Languages
I stumbled into (or was led by the spirit to) the Native American Languages Online Resources website. The Native Languages of the Americas is a small non-profit organization dedicated to the preservation and survival of Native American Languages. This website is a growing online collection of information, history, linguistics and vocabulary for over 800 indigious languages of the Western Hemisphere. There is a ton of information currently on the site, more than can be browsed in a few minutes, so make sure that you have some time to spend if you click through to the site.
They also have a webpage dedicated to supporting Native American Flute Makers.
