The Soviets under Lenin and Stalin also burned books. Many more of them in fact.

And they burned for example literally everything written in Chechen language before 1944 when they tried to annihilate the Chechens so they would leave no trace at all and it was like they never existed. Even every reference to them was removed form the Great Soviet Encyclopedia. They also killed or removed every single Chechen from Chechnya replacing them with Slavs (the last ones were hunted down in the mountains years later), uprooted their cemetaries, destroyed their pre-colonial architecture, and so on. Anyway, they did it with a huge bonfire in Grozny, they just didn't make a show out if it.

The Maoists in China, especially the Red Guards, burned possibly even more books.
