Muisca resourses

For one of my projects I'm interested in getting information on Muisca
language, the Chibcha language spoken in the Bogota region of Colombia
when Spaniards came to America.  I will probably making a bibliografical
research on printed books but I would like to know if someone on the
list knows about titles of books describing this or another Chibcha
languages or know about web resources on this theme.

I would like descriptions of phonetics, grammar, words, and related
stuff.

Thank you!
