The more I learn about the Georgian language the more eager I am to compare it with nearby Caucasian languages, to which it is not related but shares a common Sprachbund with.

Although I'm also interested in Abkhaz and Chechen, I've become mostly interested in Avar because of the Caucasian languages spoken in Dagestan it has the most speakers, it's flourishing, it's taught in schools, and is used as a local lingua franca.

Yet despite this there is an amazing paucity of information about Avar available on the internet. At least in English.

I am seeking either a grammar of Avar or a pretty detailed description. A dictionary would also be OK. I can't really pay for one and I don't have access to journals for professional linguists. Where might I be able to find something?
