" One thing you won’t find much in Australian second-hand bookshops are 1950s or earlier editions of lots of books – The Catcher in the Rye, A Farewell to Arms, Animal Farm, Peyton Place, Another Country, Brave New World and hundreds and hundreds of others. The reason for this is simple: they were banned. Altogether, at its peak, 5,000 titles were forbidden to be imported into the country. By the 1950s this had fallen to a couple of hundred, but it still featured some extraordinary exclusions – Childbirth Without Pain, for instance, whose unflinching candour in describing where babies come from was considered a little too rich for Australian sensibilities. This was just conventional titles, by the way. "
