No Eu wide bans, but quite a few in some EU countries: https://en.wikipedia.org/wiki/List_of_books_banned_by_govern...

According to that list, in Germany unannotated editions of Mein Kampf are still banned.

Seeing it in the flesh is the reason why I don't believe too many people actually read the original (and not the abridged version).

It's a brick! And poorly written at that. The man had no talent for the arts.

Wouldn't something like a book of child pornography be banned in the EU?

That's not true at all, for example in Belgium, any book that discredits genocide, incites to racial hatred, or shows sex with minors is banned from sale and/or possession. Then there's also moral rights infringement, such as obscene parodies of Tintin, books explaining suicide methods, etc, etc.
