Information on Kazakhstan is somewhat scarce and you won't be finding many tourist guide books on the country. (Lonely's Planet's Central Asia does, however, contain the best information that we were able to find and it's worth the purchase). It's a bit challenging, but the best source of information is certainly the internet.
In particular, take at look at the following webistes:
There are also some yahoo.groups that are worth signing up to, in particular: email@example.com (a group devoted to canadian families adopting from Kazakhstan)
We also have to mention the documentary "Long Way Round" by Ewan McGregor and Charley Boorman. They travel from Great Britain to New York on their motorbikes...taking the long way round... and travelling 3 weeks in Kazakhstan. It's amazing and really gives you a sense of the country and its people. We couldn't stop watching it. We would highly recommend it.
