The Soviet Union today

On Thursday nights, I am teaching an informal class for my friends' kids. Currently, we are studying the countries of the world. The book I am using intersperses countries with representative tales from the country being studied. It is pretty good, but it was written in 1974. So obviously it has a lot of old information, esp when it comes to places like the Soviet Union, which no longer exists now.

Any ideas where I could go to find current information on whatever replaced the Soviet Union?
