Sorry about this PS: I regrettably don't have "The Amazonian Languages", of which Dixon was coeditor, and where he wrote the chapter about the Arawá languages, and cowrote (with Alexandra Aikhenvald) the chapter about "Other Small Families and Isolates". But I do have his Australian languages. If you want it, all you have to is send a mail to arinbjornhersir@gmail.com. I'll then create a Dropbox folder for you. If you do want anything else, I'll perfectly willing to share. I have a good collection of books in the field of Indo-European linguistics. Just say yes or no, and If you have any wishes, I'll try to fulfill them. (History, linguistics, Physics, Mathematics, it's all there.) How's that for an olive branch? -)
