A very interesting overview of censoring books from the 1300s to today. The reasons for the bans are most commonly sex or religion, which wasn't surprising, but it's depressing that it still happens to this day. What is really sad to me is also that several of these books are memoirs, so they're not fictional, but the very experiences of the authors being banned. 

A lot of the authors are also exiled from their countries and cannot return, either officially or because they fear violence. And yet we cannot blame whatever religion or geography for these bans when they happen even in the country of free speech, as well as in my own country.

The Hungarian edition I read actually has an essay at the end which talks about book censorship in Hungary's history, as well as the new, currently in force regulation that requires books with LGBT topics to be sold wrapped in foil, and bans them from being solved within a certain distance of schools or churches.
