Belated thanks and Mohawk question, was Re: Head-marking languages and adpositions?

A month and a half ago Dirk Elzinga and Jesse Bangs gave me some useful
pointers on finding out more about head-marking languages.

In particular, Jesse wrote in response to my question about languages
that exemplify different features:

> Turkish as agglutinating, nom-acc, dependent-marking
> Mohawk (or related langs) as polysynthetic, active
> Tagalog as trigger, head-initial, head-marking
...as a result of which I ordered the Kanyen'keha Tewatati (Let's Speak
Mohawk) book and tapes and am enjoying the language.

The book is better than many NA language guides - it's more than just
a phrasebook, and does have some grammar - but I need to know more.  There
have got to be more processes than just the ones they provide.  Does anyone
know some good references for Mohawk, maybe a comprehensive grammar?

Thanks!
Amanda
