In 2005, Australian literary historian Nicole Moore discovered a nearly-forgotten archive of her country's banned books packed in nearly 800 boxes stored seven stories underground in a government repository. Moore ended up writing her own book, The Censor's Library, about the history of Australian's literary censorship. I think a great next step would be to open a public library stocked only with the once-banned books. From the Sydney Morning Herald:
As Moore shows, such secret collections have accumulated in many parts of the world, often carefully tended by censor-librarians. Private Case, Public Scandal, the book that revealed the contents of the British Library's secret collection, was itself banned in Australia in 1966. Not surprisingly, the 20th century's largest and most notorious repository of forbidden literature was in the Soviet Union, with more than 1 million items.
