What I haven’t seen mentioned in these discussions is where the mental association of “banned books” comes from.
In America, at least, the school curriculum spends a lot of time talking about dictators. It mentions, numerous times over many years of a child’s life, that something dictators often do is to ban books that could make people question them or that could make people support people the dictator doesn’t like, etc. In all such cases covered in the school curriculum, dictators’ “banned books” are not allowed to be sold in the country at all, and are often destroyed, sometimes even in mass burnings.
So, this is the psychological association people typically have with the phrase “banned books”.
The news articles over the past X years declaring something like “Government Y bans books!” seem to be leveraging this mental association to give people the emotional impression that Government Y is doing dictatorships things. I think this is why people get annoyed, since not allowing whatever books in the school library is not a dictator thing (okay dictators do it but it’s like drinking milk or being against animal cruelty, it’s not something that is primarily done by dictators).
So, when people say that not allowing a book in a school library is a type of ban, they are correct, but they ignore this association which most people have from school.
That’s how we got to Dua Lipa doing a promotional photo op holding up books that can be purchased on Amazon and delivered to your Kindle to read immediately. Attaching the “banned” word to a book turns the purchase into an act of rebellion and a reason to talk about it, and the marketers are not going to waste that opportunity.
That’s why the “banned books” category has been expanded so much to include not only books that governments or corporations have tried to suppress, but also books that some school board in Kansas decided shouldn’t be included in the elementary school library.
Unfortunately once a term becomes this overloaded it loses meaning. The original topics of government censorship and oppression get less attention because it’s drowned out by pop stars holding up Margaret Atwood books for photo ops and people buying books on Amazon as a form of slacktivism.

Everywhere throughout all time is obviously not authoritarian, so the definition fails. Sorry, you are wrong.
Dua Lipa wasn't doing a photo op with Maus. In the photos she's posing with modern books that are still being promoted by their publishers. I'm not familiar with all of them, but a quick search shows one of them is not appropriate for elementary schools because it includes essays debating which sexual acts are appropriate for feminists to perform and other adult topics. Why is it "authoritarianism" to say that a book like that doesn't belong in my kids' school library?
This is a promotional stunt, and I'm surprised more people aren't seeing through it.
And no one really pretended that these cases were cases of "banned books".
The problem is when authority bodies (school, government, ...) start to include, in these "normal non-appropriate" books other books not because they have bad societal consequences when the reader is not mature enough, but because they don't like the content for ideological reasons.
I think it would be a very bad faith argument to argue that reading Maus will lead to people less socially adjusted.
And, sure, some "banned" books may be inappropriate. But as soon as these authorities have open the doors to arbitrary banning books, they poisoned their own well: maybe under "normal" evaluation this book should be removed from the list, but they removed it "the bad way", they failed the process, and therefore the ban itself is illegitimate.
It's a bit like the procedural miscarriage of justice: if you mess up when arresting someone, they can be freed even if it turns out they were guilty. Or in a more topical subject: the Fifa can reverse some decision, but if they do it in the context where they received phone calls from the US president, then it's a big failure in the process, even if a "normal" re-evaluation should indeed have concluded to reversing the decision.
Two things can be true at the same time: a book can be both banned in one place, and used to promote someone's brand in another. Somebody in a deeply repressive and abusive home will not have a better or worse life if Dua Lipa did not exist.
If I'm prevented from bringing my dog into a restaurant, that doesn't mean that dogs are banned. It means I have to go to the restaurant on the other side of the street.
If McDonald's doesn't serve any hard liquor it doesn't mean that alcohol has been banned in the country.
However, Catcher in the Rye is banned not primarily for these nuanced misreadings, but instead primarily for its profanity. Meaning if we stripped the profanity out, this dangerous book would likely never have been banned in the first place. When you allow these bureaucratic institutions to ban books, they are not going to Socraticly reason through what should and should not be banned in a rigorous manner. They are going to ban books that vibe against their “sensibilities”.
Given that we do not have philosopher kings making these ban decisions, the least bad option is to not have any ban. Encourage kids to read broadly and get many different perspectives. More importantly, teach them to act as a scouts who should be proud/excited when they find a new opinion other than their own — and even more excited to find an opinion better than their own to adopt — rather than a warrior who is proud that their previous opinion was “right the whole time”. Sometimes your old opinion was proven right by new information, but that should not make you excited/proud. I’m confident that if all children are taught this scout-mindset that solving the intractable problem of banning books “correctly” would be completely unnecessary. Matter of fact, having children build immunity to bad ideas through learning how to be a “good scout” would be strictly better than making little bubble-boys who are safe from bad ideas only because the thin bubble the “philosopher kings” set up for them. The latter bubble makes children’s immune system unprepared for the real world while the scout mindset helps build hyper-capable, curious, and civically engaged adults.
They bought some books for their kids from a banned books list thinking they were "banned" for thought-control reasons, but opened one up to find an illustrated guide to using mobile phone apps to find partners for anonymous hook-ups and a guide to following through with it.
The book clearly wasn't appropriate for their young children, so they hid it away. Now we joke that they've also banned the book.
Demystify such nonsense
Except it's not, or it couldn't have continued to radicalize people to this very day.
Like the bible people mostly know the parts of it that fit their own agenda.
And don’t underestimate the effect it has if you are forced to read a book in school from front to back and write essays about it.
There may be books which radicalise people. But I'm fairly sure Mein Kampf is not one of them.
The book can still be printed, bought, and read. It can be brought into that same school, and read there. It’s not banned.
Sun Tzu did say "appear weak when you are strong".
It is not clear to me from the reporting if Manifesto Library is a translation error or if it really is a library within a bookshop.
I suspect it's neither and more like an art installation.
And barely a bookshop at that, more of a tourist attraction. You need tickets to enter, and the main selection of books are classics, mainly public domain iirc. They have more recent/interesting books but only as decoration (I asked to buy a Naomi Klein book, they refused to sell it). Most people are just there to take pictures because the stairs inspired Harry Potter.
Considering the length of the line to get into that place, I'd wager you're correct.
So I think they are aware of the “false friends” words.
With that said, I don’t think it’s an actual library, more like, as you said, an art installation, an exhibition, a space for highlighting books.
I've been to lots of bookstores with sections or displays for famously banned books. I'm pretty sure my local Indigo (basically a Canadian Barnes & Noble) has one. If that's all this is then it doesn't sound especially newsworthy outside of the celebrity involvement and maybe the renown of this particular shop.
OTOH the article describes it as a "permanent" installation, which does sound a little different from what I'm picturing.
Even discussing a taboo topic may cost someone their freedom, if not their life.
If you have book that are actually banned in these countries, I don't think many people will call it awesome.
Books are typically banned for:
- copyright: not really a ban, but the copyright holder simply doesn't want it to be published the way you want it to be, doing it anyway is just piracy. It can be seen as "brave" if the copyright owner is an asshole, but doing that to authors you support is not great.
- hate speech: Germany for instance bans most Nazi stuff, whether or not it is a good thing is debatable, but in any case, what do you think the political message would be if you opened a Nazi library. Most other European countries have similar laws to some degree.
- porn: Need I say more? Special mention to child porn, which is super-banned, and definitely not awesome.
- libel: some people hide behind defamation laws to avoid criticism, but in most cases, these are actual lies and you don't want that.
I don't know of any banned book in Europe that anyone "woke" (for a lack of a better term) would want to put forward.
>The main source for the events of the battle is Herodotus. According to his account, the Spartans held Thermopylae for three days, and although ultimately defeated, they inflicted serious damage on the Persian army. Most importantly, this delayed the Persians' progress to Athens, providing sufficient time for the city's evacuation to the island of Salamis.
>Though a tactical defeat, Thermopylae served as a strategic and moral victory, inspiring the Greek forces to defeat the Persians at the Battle of Salamis later the same year and the Battle of Plataea one year later.
I've actually really been a fan of her, and her music before I heard about her Service95 endeavour. So seeing that video led me to looking into her Service95 work, and yeah, I have to say, she's the real deal.
Two of my favorite examples of grammatical importance:
Seriously though, good on her.
If they were banned in Portugal it would run afoul of the legal system, and probably be closed down, obviously.
But if the criteria of being in the library - that the book be banned somewhere in the world; that's a reason to visit the library in of itself.
Though I think there's going to be a lot of garbage, one need only remember that Life of Brian (the Monty Python movie) is banned in the Vatican. (along with a bunch more).
Sometimes just seeing what is banned and where is a sort of art in of itself.
I can find no confirmation of this, or of any ban since 1966 (and that is assuming that the index of forbidden books had legal force in the Vatican).
> But if the criteria of being in the library - that the book be banned somewhere in the world; that's a reason to visit the library in of itself.
Is it worth a visit to a physical location? A lot of those books are ones I could see on a list and order online. Its not really that interesting if a book as been banned somewhere very authoritarian, nor am I that interested if schools in one area somewhere were not allowed to have a book in their libraries. On the other hand reading down this list is very illuminating, and often astonishing:
https://en.wikipedia.org/wiki/List_of_books_banned_by_govern... I am still scrolling down it, but Austria, Australia and China are all fascinating.
(Some but not all country grids do list unbanned dates.)
Some historical bans and the reasons for them are very interesting too.
https://www.thewoodword.org/entertainment/2023/04/03/reeling...
"Banned" feels like a slightly clumsy word to use to describe restrictions such as these.
The museum is in Portugal. It is not specified where those books are banned.
People on this site have some really bizarre ideas about what constitutes "clickbait".
I think though the library is supposed to be a general, worldwide collection of books that were censored/banned anywhere in the world, the physical location of the library just happens to be in Portugal. That's how I understood the article at least.
¹ literally banned, i.e. it was illegal to buy, sell or distribute such publications in the state: https://www.irishstatutebook.ie/eli/1929/act/21/enacted/en/h...
Unsubsidized is the more accurate word here. Some governments have chosen not to pay public money to stock these books in libraries, but no government has created criminal penalties for ownership.
It may be the case that her library includes some books that genuinely carry criminal penalties, but the article does not provide enough info to assess that.
People who are canceled are not literally thrown in prison and executed.
Right, that's the problem
> but last century produced wittgenstein;
I don't think a philosopher who died 80 years ago is driving the change in how words are used in the last 20 years. It has more to do with the Internet and the cultural forces driving people to use hyperbole or make things up to make money in the attention market. This article wouldn't be on HN if it was just about Dua Lipa starting a bookstore, they added "banned" so it would catch peoples attention even if that's basically a lie.
> perfectly clear communication was always a polite fiction.
The comment I replied to is trying to argue that it's ok to call books "banned" even if they're not banned, because it's like the term "cancelled" which at one point meant someone whose content was actually cancelled but I guess they're suggesting it doesn't mean that anymore either.
I'm not arguing that words should have perfect meanings, that is obviously a strawman, but this article and comment thread are using words to mean the complete opposite of their common meaning.
The phenomenon is not restricted to this century. Orwell's book published in 1949 includes many prescient examples. Witgenstein's contribution, at a minimum, is that he named the paradigm, thus raising awareness, and perhaps leading to an increase in intentional engagement with these practices.
Is it a problem? I think it allows greater flexibility for humor and subtext than ever. It's the people who insist on contextualess interpretation that rain on the parade.
> it's ok to call books "banned" even if they're not
First of all, of course it's ok. Nobody is getting hurt. Second, the books are banned—just not where the bookstore is. I'm not sure how anyone could struggle to understand this. Anyway, what book is banned everywhere? Has any book in history really been banned to such an extent? Or do you really think Dua Lipa would be investing in a bookstore that would immediately be shut down? Being upset at this just seems like a waste of energy.
In fact, I would go so far as to say that for the most part it's the people who do believe in canonical definitions that get hurt by thinking they communicate clearly, by allowing others who do have a more flexible understanding of semantics undermine and fool them. We should teach words as polysemous by default so as to ensure they're able to function in the modern world. Hell, a great deal of wordplay can only be enjoyed if you're able to hold multiple definitions in your head at once.
For instance, "literally" notoriously connotes "figuratively".... sometimes. This is actually quite an old phenomenon that well predates the internet. But it allows ironic commentary on the speaker's perspectives that forces the audience to interpret the phrase in a broader context.
There is certainly a role for formal, unambiguous speech—in technical communication, in legal briefs, in analysis more generally—but it's not hard to see why people enjoy straying far beyond that in service of fluid, natural, and concise communication.
It has more ambiguity because we had many similar words for similar things that are differential in some minor way.
Now everything can mean anything, it is leaning more expressive with less precision, English's best quality is that it balances the precise and the expressive, the craft is gone and if you misunderstand what I've written because I've used the wrong words that's your fault.
I don't think you're this unable to discern meaning. I have faith in you.
> if you misunderstand what I've written because I've used the wrong words that's your fault.
You could say the same thing about how you're reacting right now.
A more accurate term might be "politically unfavorable", but that doesn't get people riled up. And, I'm just going to take a wild guess here, but this library is probably zeroing in on books that are politically unfavorable to conservative governments. I doubt we'll find the likes of Mein Kampf in there.
Language is mutable and alive and ever-changing. That's just how it goes.
+Used to mean 'inspiring awe'

For example, North Korea has banned most western books so my local Barnes and Nobles is pretty much a banned book store.
Whether books by e.g. Jared Taylor are also "banned" in this manner in the UK is left wonderfully vague - the only way to find out is to be found possessing one, and then see if the government prosecutes you. You get chilling effects for free, and avoid the bad PR of a "banned books" list!

Are there examples of these?
The few examples mentioned in the article are easy to buy, at least in the US. Is there a full manifest somewhere?
https://www.service95.com/manifesto-library-launch looking here, it seems the best case would be Navalny, although he wasn't really killed for his book per se, but rather his political opposition.
Here in Poland we had "Mein Kampf" by certain Austrian painter in my primary school library for example.
According to that list, in Germany unannotated editions of Mein Kampf are still banned.
It's a brick! And poorly written at that. The man had no talent for the arts.
A quick check here in the States showed all of them available on Amazon for under $25 each.
The term “banned books” has become a pop culture meme. In this context it doesn’t literally mean banned, it means the book wasn’t allowed somewhere. In extreme cases a government in a controlling country may have forbidden the book.
However in a lot of cases the “banned books” were just not allowed in some school’s library for kids somewhere.
That’s why all of the books aren’t actually banned in the US and are readily available, unless maybe you’re a 3rd grader looking for them at some school library that probably wasn’t going to order the book for kids anyway before it became “banned”
and what is a good word to use when something isn't allowed somewhere? perhaps... "banned"?
i dont understand why people think something needs be unavailable globally to be considered "banned".
there's a million examples of the word "banned" being used when X isn't allowed in Y context. people only get touchy about it when it comes to books for some reason.
dang bans people from HN, no one gets upset about the use of the word "ban" there, despite it being a context-specific ban.
We don’t call R-rated movies “banned” because we’ve decided not to show it at schools to kids. That’s why it’s confusing when we switch to books and the word “banned” means somebody, somewhere, decided it wasn’t appropriate for kids in their school or something like that.
dang bans someone from HN? no confusion. alcohol banned in public? no confusion. weapons banned from schools? no confusion.
books? oh my god, they aren't banned they just aren't allowed
Notice how all of those bans include a specific context? From HN, in schools, in public.
No confusion.
Notice how the only context in the headline is “in Portugal” but the books are not banned in Portugal?
Confusion.
It’s really not hard.
the word "banned", specifically and only in the context of books, is one of the fucking strangest quirks of HN.
Banning books for example has a very different context than banning cocaine. Cocaine use in the United States is banned, Hustler magazine is not. I can swing by the store tomorrow and pick one up legally, I can't get cocaine legally.
Restricting Hustler from a school full of kids is not banning it. Thus the quirk.
If I don't allow Green Eggs and Ham in my house does it belong in a museam of banned books?
no, its not.
>Restricting Hustler from a school full of kids is not banning it.
only if you are making up your own definition of "ban".
by any dictionary definition, it is completely appropriate to say hustler is banned from the school.
Something actually inaccessible? imgur.com in UK, and soon many others
US book banning is mainly schools and parent groups strong arming libraries and educators to forgo specific books.
In the name of literacy, we need to use words properly.
[1] https://pen.org/book-bans/book-bans-frequently-asked-questio...
> "any action taken against a book based on its content and as a result of parent or community challenges, administrative decisions, or in response to direct or threatened action by lawmakers or other governmental officials, that leads to a book being either completely removed from availability to students, or where access to a book is restricted or diminished."
Though this is a fascinating definition.. anytime, anywhere says "no thanks" to carrying a book outside of purely budgetary or physical space limits, it is now a "ban".
The more fascinating question would be discovering the boundary of what PEN, et al consider a "good ban" because I bet we could come up with a few.
That's not what the definition you just quoted says. In fact, the definition you quoted is very close to the common definition of "ban": a refusal to allow something, usually by an official entity.
It matters a lot who does it.
I feel like if they'd still let the person read the book by themselves, and freely share it with others, then indeed it's merely a curation choice. But, if I'd expect, they try to prevent this person from reading their own brought book or sharing it with others, then I think it's fair to say that book been banned and/or censored, at least in that particular location.
Is a specific institution or library are banned by their decision makers to have a book - that book is banned in that context. If you don't buy this that fair, but don't come at me with your pedantry when I just answered your question.
By that reasoning, all PG-13 and R rated movies are "banned" just because your elementary school library doesn't carry them. Absurd, huh?
"10000s of people" can create new definitions of words as they choose, just don't be surprised when educated people think they're fools.
“We aren’t including this book in the library because we don’t have space for every book.” <—— not censorship
“We aren’t including this book because we don’t think it’s appropriate for kids to learn about trans people.” <—- censorship
Removing books from public libraries (not just schools) because we find criticism of certain ideas around gender to be offensive <-- definitely censorship
Isn't this basic curation and child protection, not censorship?
When people ban books because they don't want others to learn about trans people, they're usually pretty vocal about their motivations.
Because that’s the standard you’re using for ”censored in the US”.
Further, when people talk about banned books, they usually mean at some sub-country level, even down to a school board. Like if you look at -
https://pen.org/banned-books-list-2025/
- these books weren't banned from the United States, but they're controversial enough that individual school boards or library systems removed them.
Either way, I agree with your comment that there is nothing dangerous about Atwood unless you are a fan of authoritarian religious governments.
1. Regime change doesn't happen instantaneously. The Francoist line of thinking was still pervasive after Franco died, and through the 70s there was a waxing and waning of censorship.
2. The book was still restricted in multiple states, the spirit of my comment still stands.
- Books that are simply bad books and in addition to being bad take an aggressive, political bent. (eg: the handmaid's tale)
- Books that seem relatively anodyne, and it's not clear why they were banned. (eg: the perks of being a wallflower)
- Books that governments might have feared in the old days, but are now much less threatening than other more readily-available material. (eg: 1984)
I still think, even in these crazy, censorious times, that people who love banned books list are (intentionally or not) hearkening back to an older time when a centralized body could actually prevent access to information. Instead, modern book-banning feels much more symbolic. ie, "we do not approve of this book!" rather than effective. Anyone can buy the book on Amazon, or pirate it for free, or find countless video reviews which contain its ideas. And importantly, find many, many more extreme, subvesrive, rebellious, etc. ideas for free online.
Of course I do not support the banning of the books, but I think sometimes once a book is banned this act gives the book power -- in more senses than one. Less discussed is that the fans of the book often believe it to be better than it actually is, merely for being banned.
Popping in to point out that novels are not "information" in the sense of being lists of facts or ideas. The medium is part of the message. That's why novels can be banned but a list of the facts/ideas are often not.
Reading an AI summary of a novel is not even roughly equivalent to reading the book. (Before AI, there were handwritten summaries like Cliff's Notes that served the same purpose of allowing a person to gain a superficial understanding of a book.)
For example: one could list the key facts of _Roots_ (banned in school libraries in the author's home state of Tennessee in 2026) and not convey the points of the book, which is embodied in the totality of the work. Incidentally, _Roots_ was banned for integral parts of the message of the book.
I'd still hold that you can just get ahold of books these days if you want to, but your point stands that the mere spread of ideas is not equivalent to really reading the whole book.
Handmaid's Tale is actually a pretty decently written book for a dystopia. You just need to like dystopias.
"Atwood was also inspired by the Islamic revolution in Iran in 1978–79 that saw a theocracy established that drastically reduced the rights of women and imposed a strict dress code on Iranian women, very much like that of Gilead." - https://en.wikipedia.org/wiki/The_Handmaid%27s_Tale#Composit...
From Atwood herself (https://lithub.com/margaret-atwood-on-how-she-came-to-write-...)
"The deep foundation of the United States—so went my thinking—was not the comparatively recent 18th-century Enlightenment structures of the Republic, with their talk of equality and their separation of Church and State, but the heavy-handed theocracy of 17th-century Puritan New England—with its marked bias against women—which would need only the opportunity of a period of social chaos to reassert itself."
https://www.patreon.com/DarvishIntelligence/posts/handmaids-...
From Atwood herself:
"The deep foundation of the United States—so went my thinking—was not the comparatively recent 18th-century Enlightenment structures of the Republic, with their talk of equality and their separation of Church and State, but the heavy-handed theocracy of 17th-century Puritan New England—with its marked bias against women—which would need only the opportunity of a period of social chaos to reassert itself.""
"Like the original theocracy, this one would select a few passages from the Bible to justify its actions, and it would lean heavily towards the Old Testament, not towards the New.
[...]
Surely the Gilead command would have moved to eliminate the Quakers, as their 17th-century Puritan forebears had done."
"I made a rule for myself: I would not include anything that human beings had not already done in some other place or time, or for which the technology did not already exist. I did not wish to be accused of dark, twisted inventions, or of misrepresenting the human potential for deplorable behavior. The group-activated hangings, the tearing apart of human beings, the clothing specific to castes and classes, the forced childbearing and the appropriation of the results, the children stolen by regimes and placed for upbringing with high-ranking officials, the forbidding of literacy, the denial of property rights—all had precedents, and many of these were to be found, not in other cultures and religions, but within Western society, and within the “Christian” tradition itself. (I enclose “Christian” in quotation marks, since I believe that much of the Church’s behavior and doctrine during its two-millennia-long existence as a social and political organization would have been abhorrent to the person after whom it is named.)"
Weird example. The Handmaid's Tale is quite good.
Edit: wow, downvotes for stating a book is quite good. HN at its worst.
Edit 2: in fact it's so bizarre, also seeing other commenters here downvoted for saying Handmaid is a good book, that I struggled to see the reason for the ire. I'm not from the US, mind you, so it took me a while to add 2 and 2 and remember Atwood and Handmaid are in the current political climate of the US an anti-Trump stance. So that has to be the reason. Saying Handmaid is a good book implies you're anti-Trump and therefore invites downvotes (but also upvotes from the other camp, I'd guess). Wow.
The book and show have little in common, and holy hell the show got up its own ass more often than not.
> It was a thinly veiled world-building exercise on the subjection of women in Islam… then it ends. Nothing really happens.
The Handmaid's Tale wasn't about Islam but about religious Christian fundamentalism and, by Atwood's own words, an extrapolation of trends she saw in the US.
It's a good book, it seems contentious to list it as a "bad book" as a given, and expect people to agree with you. It's an acclaimed book and well received by other authors.
> Nothing really happens.
Bizarre take.
In structure it has a lot of parallels to 1984, the protagonist is trapped in an oppressive regime seemingly without escape, some authority figures are ambiguous, there's some hope but it can turn into a trap, and finally a sort of open end (both Winston's and Offred's fates are implied but unresolved, though Offred's is more ambiguous) and a an epilogue explaining the regime and its implied downfall.
Do you also find 1984 as a novel where nothing happens?
This is exactly my point you people are trying to make warnings and hysteria about fundamentalist religions… while bending over backwards to defend a fundamentalist religion that today subjugates women, and is the last remaining source of slavery in the world.
“I still think, even in these crazy, censorious times, that people who love banned books list are (intentionally or not) hearkening back to an older time when a centralized body could actually prevent access to information.”
You don’t think a school library can prevent access to information? Poor people exist.
I just don't think you can prevent access to information the same way, though. There will be at least one smart phone in the house. There will be friends and relatives with smartphones, with computers, etc.
A poor person who lacks the resources to query on youtube for videos or wikipedia for research will also not be able to sit through a full-length novel.
[edit]
In the 1960s it may yet have been true (despite radio and shortwave) that if your local libraries and shops did not contain a book -- if your friends had never heard of its ideas -- that you would truly remain ignorant of some of the subversive ideas out there. Things just do not work that way these days. Ideas spread faster and farther than ever. You really cannot prevent the spread of information the same way.
At best, you can create a culture of censorship around certain information, which is what I believe modern book-banning does. My quibble here is that people seem to treat book-banning as if it's 1890, and the ideas are being killed due to lack of spread. In the modern world, book banning is symbolic and helps to identify ideas as subversive and unwanted -- but they are NOT out of reach.
Again, I do not support book banning whatsoever.
