I am too young to remember the seventies
, but I went to 'Ultra-Orthodox' Jewish aka 'Hasidic' High schools. I read many banned books, but you probably wouldn't believe many of them were banned. I had a book about aquarium fish confiscated because it supported evolution, Harry Potter books confiscated either because they had poor morals or supported 'kishuf' aka magic, and have hidden many others well. Most of the bans where just there because someone made a blanket ban 40 years ago and it lingers, but it is still funny.
