banned
Regime-banned books are in school libraries and on indigo bookshelves at eye level for children.
REAL banned books are often decades out of print, going for hundreds of dollars used on eBay, they've been disappeared by publishers and distributors in spite of interest and demand. Others have authors who've died or been imprisoned for their ideas, yet more have been removed from city or university-wide library systems so that their "Misinformation" and "Lies" do not poison impressionable scholars.
Yet more are suppressed algorithmically, not appearing on the author's wikipedia page and not appearing in Google search if you type the author and "book" or "memoirs"... but only appearing when you already know the full title of the work (try this yourself: Type in "Pinochet Memoirs", and then type in "Pinochet: A journey through a life")
Yet others are explicitly banned, some to the point where a mere PDF on your hard drive can result in a decade-long sentence... IN THE UNITED KINGDOM, NEW ZEALAND, and AUSTRIA.
This has been a massive project. over 200 titles on the full list and 10,000 words in my "Cursory" survey.
Let me take you on a journey into the heart of the forbidden
