Book-burning specifically, no, but the Nazis destroyed a lot of research from a German institute that studied gender issues. Knowledge of the place and some of its research still exists, but a lot of the research was simply gone once the Nazis rose to power. That seems like way less of a liability these days with the internet, but even that is prone to government meddling, and when the people that agree with book burnings run the government, well, there's a very famous prescient book on the topic.
