Alright kiddo, let me explain what a bibliography of the post-Stalinist Soviet Union means.
A bibliography is a fancy word for a list of books and articles about a specific topic.
Post-Stalinist refers to the time after Joseph Stalin, the leader of the Soviet Union, who died in 1953. So, we are talking about the books and articles that were written about the Soviet Union after Stalin's death.
Now, the Soviet Union was a big country and a lot happened there during this time period. Some people wanted to write about their experiences, while others wanted to study the politics, economy, and culture of the country.
So, a bibliography of the post-Stalinist Soviet Union would be a list of all these books and articles written by different people about different topics related to the Soviet Union after Stalin's death. It's like having a big list of books and articles that tell us about what happened during this important time period.
