Talk:List of best-selling books/Archive 6

Political and religious books
We should remove the statement:

All books of a religious, ideological, philosophical or political nature have thus been excluded from the below lists of best-selling books for these reasons.

There are three problems with this statement, the first two are less relevant given the power of the third, but I will lay out all three.

Firstly it is hard to define what it would and wouldn't cover.

Secondly we have political and religious works in the list, for example Animal Farm and The Gospel According to Peanuts. (As the IP noted above, the Narnia books also fall into the religious category.)

Thirdly it does not follow from issues surrounding the Bible, the Quran and the Little Red Book, that other political and religious books will have the same issues (though certainly some will, Mein Kampf and to a lesser extent the Communist Manifesto are good examples, as is the Book of Common Prayer). These issues relate to the multitudinous editions published, the global reach of the books, and the fact that a significant proportion was published in places and at time where no sales tracking existed, and that a significant number were given away. The gifting aspect is really the only thing that distinguishes these books from, say, The Mabinogion' in terms of understanding sales volume.

The following religious and political works from my shelf, for example, are all likely to have as good a record of sales figures as any contemporary novel.


 * The Gospel of St. Luke G. B. Caird, Penguin, 1963
 * Theory and Methods of Political Science, Marsh and Stoker, 1995
 * The Road to Serfdom, Hayek, 1944
 * Religion and the Racist Right, Barkun, 1997
 * Lenin, Weber and Weber, 1980
 * Decentering the Center, Narayan and Harding (eds), 2000
 * Feminism/Postmodernism, Nicholson (ed), 1990
 * Lukacs and Heidegger, Goldman, 1960 (Fr original Lukacs et Heidegger)

All the best: Rich Farmbrough 13:25, 16 December 2020 (UTC).


 * Religious and political books are (or claim to be) non-fiction books: Narnia, Animal Farm, LotR, ... all don't fit that category. They may be influenced by religion or even consciously or not try to promote one religion or political view (as do countless books of course), but they are not books laying out the fundaments of a religion or political system. More importantly, they are not books aggressively pushed by a religion or political party or regime: not books that get handed out for free to convert people or to strengthen their belief, or books that people were obliged to own or risk severe punishment (like some political books). The list is for sales, not for number of books printed, and with these two categories this gives problems. Not the sole problems, as the figures for these books vary extremely from one source to another and lead to heated debates between adherents of oneor the other (even more so than e.g. the LotR debate here). Finally, especially for the Bible: there is no "The Bible", there are many variations, including some extra books, excluding others... so we're not even talking about one book here, but about a variety of books commonly given the same title.
 * Oh, and you have good sources indicating that e.g. a biography of Lenin sold more than 10 million copies, then of course add it to the list. It's not a political book, it's a biographical book about a politician. Basically, manifests produced by churches, political parties, governments, or people wanting to start a church or political movement, are the ones covered by "religious or political books". Books about and even less novels inspired by religion or politics are not included. This seemed rather clear for most people over the past 10 years or so. Fram (talk) 14:17, 16 December 2020 (UTC)

Sorry for not replying on this sooner, my mum has been poorly. I agree with Rich.

Fram I would disagree on the point that religious and political books claim to be non fiction. In both religion and philosophy allegory has always been an important tool. "Objectivists" draw all their interpretations of Rand's thinking primarily from her novels Fountainhead and Atlas Shrugged.

I agree on the point that it should be on sales not printed. However if a source to support a sales figure I think that should surfice for inclusion.

I'm not sure how you could argue a biography of a political figure isn't inherently political as it will be written with a view by the author on the individual's views.

Essentially all non fiction books unless technical like a dictionary, will be putting forward an argument, or a viewpoint, it maybe Dr Spock on the best way to raise a child or Donald Trump on how to make to a deal, it will likely fall on one side or another in a debate, even if it is between experts in the field.

I would argue that we have to accept some estimates. If a source says best selling, or has sold I don't we can second guess the quality of that source. — Preceding unsigned comment added by 92.11.89.15 (talk) 03:19, 4 January 2021 (UTC)

LOTR again
An IP has removed LOTR (and possibly the Hobbit) from the list. They have been inserted in the lead along with Monte Christo, Two Cities and Don Quixote as books whose sales numbers are unknowable, and ascribed to the same source. That source says:

There is no suggestion here that the LOTR figures are unknown, let alone unknowable.

I have attempted to be accommodating, by tagging the un-supported statements rather than removing them, but this has been reverted, I can see no way forward at the moment other than requesting semi-protection, or as a last resort, AfD, which would be better than allowing the article, which has inherent problems, to slip into absolute chaos.

All the best: Rich Farmbrough 22:26, 9 December 2020 (UTC).

Rich the article you cite, isn't a privileged source, and it is also problematic as the writer is referencing your opinion so it is a form of its own citogenesis based on your views. The source only presumes the independent lifted it is material from wikipedia there is no evidence it did.

Also I think suggesting the article be deleted because you don't like it or your favourite book isn't the top of the list is a bit extreme.

I have some sympathy for your position as wikipedia isn't an independent observer it is used by millions including journalists.

Essential though you seem focused on removing any book that might be above LOTR as novels like the little prince you remove because the author's estate you claim has inflated them, yet couldn't the tolkien estate or warner bros do the same? you claim public domain works are unknowable yet the list below where LOTR appears is full of them for example War and Peace figures cite a source only in Russian yet you have never raised issue with that. You only problem with Little Red Book or Communist Manifesto is they are above LOTR as books like Mein Kampf you were happy to leave in. You criticise sources but only if they put a book above LOTR for example the telegraph article.

I think everyone has tried to be accomodating Rich but you don't own the article. I think you have to accept two things some sources will be based on estimations, and that we can't write off every source based on the fact it was published after this article was created and the circumstantial cases you build to delete sourced material are original research at best.

Also you never raised an explicit discussion to specifically dispute the source on a Tale of Two Cities and Communist Manifesto. — Preceding unsigned comment added by 84.13.85.156 (talk) 10:50, 10 December 2020 (UTC)
 * Can you try and use proper capitalisation? Can you also stop making allegations as to my motive?
 * Lets address the two you guess at - I like this article, but it's not clear that it is sustainable, I like Tolkien's work but I also like Rowling's, and the Bible, and many other books.
 * I am very disappointed that we have had to make the article semi-protected, as I am against protection in principle, but recognise that we need it in practice.
 * We have established consensus on many of these items in the past. Please read the archives on each item before you challenge it.
 * As far as Tale of Two Cities is concerned, I put considerable effort into checking the references, including contacting the authors or publishers of references who did not cite their source. All those who replied confirmed that they had taken the figures from Wikipedia.
 * You need to do research, not just argue for the sake of it, if you want to change people's minds. Also try addressing a single issue at a time, rather than jumping between random subjects

"As far as Tale of Two Cities is concerned, I put considerable effort into checking the references, including contacting the authors or publishers of references who did not cite their source. All those who replied confirmed that they had taken the figures from Wikipedia."

But that would be original research.

I think more generally you are trying to solve a problem that is impossible to solve at this point just because you and a particularly journalist think Tale of Two Cities sales figures are unknowable doesn't invalidate all other sources.

The only hard data source we have found for LOTR shows sales of less than a 1 million in the UK and doesn't show the Hobbit at all which make the figures unlikely given how much those books popularity depended on their movie franchises. So your special treatment and focus on any book placed higher than those seem inconsistent.

For example someone recently added a source for catcher in the Rye I check the date of the article (July 2011) and the version of this article that appeared at the time which already had Catcher with 65 million listed. Is that likely to be citogenesis?

And again speaking to your focus solely being on whatever was above LOTR, Jane Austen is on the list and she predates Dickens were are her numbers reliable? similarly War and Peace is on the list with a somewhat dubious russian source, yet any dickens that appears irrelevant of the number or quality of sources you delete because it might mean another author was ranked over Tolkien.

You can't just deleted sourced material be it tale of two cities or the communist manifesto (which can't of been citogenesis) because it means LOTR won't be top of the list. — Preceding unsigned comment added by 79.66.34.195 (talk) 14:43, 19 January 2021 (UTC)

Leaving out the best selling books from the best selling books list is wrong
The logic of this statement: "All books of a religious, ideological, philosophical or political nature have thus been excluded from the below lists of best-selling books for these reasons." is plain wrong. "...that lack comprehensive sales figures..." The sales count of these books are also obviously higher than that of most entries present on the lists. The correct way is to give the estimation range for all these uncertain volume books, either within the existing blocks or in a separate category. The fact that the numbers are uncertain can also be explicitly stated. Readers come to this page to see the best selling books in history, and the best selling books in history are actually not listed here. This list is then missing its point. --Csdani84 (talk) 09:26, 6 October 2021 (UTC)

--- UPDATE: Outrageous to erase books. The religious book "Alcoholics Anonymous" that has sold 40 million copies is missing.

This is a violation of the most basic of truth principles.

Someone is IMPOSING with oppression one religious denomination -- atheism -- onto millions of others, a violation of First Amendment Rights.

CONCLUSION: The list of best selling books should be the list of best selling books.

Wikipedia outrageously is allowing oppression of one denomination -- atheism -- onto the millions of people not of that denomination.

How many of these books are sold as opposed to given away? Communists during the 20th century gave away more copies of the Communist Manifesto and the Little Red Book just so they could say they were the best selling books/most popular books of all time. I've never know anyone buy Alcoholics Anonymous, or the Bible. As such they aren't best selling as so few are actually sold. They might be the most published or most in existence. — Preceding unsigned comment added by 82.33.24.203 (talk) 21:12, 12 January 2022 (UTC)

I was looking for updated numbers, and found an estimate for The Hobbit of 140 million. However, it doesn't cite where the estimate came from. Anyone have any thoughts on updated figures?

 * I do not recommend using this source. This list is exactly the same as the best-selling books list on Wikipedia at the time of publication: September 2021. This leads me to believe that Newsweek lifted the list and the sales figures directly from Wikipedia itself. As per WP:CIRCULAR, sources that rely on Wikipedia for its information should not be used in Wikipedia itself because Wikipedia is user-generated. As for the 140 million sales figure for the Hobbit, that is close to what the sales figure for the book was at the time: 140.6 million. However, it was cited to the Statistic Brain Research Institute; a website of unknown reliability with no article on Wikipedia. The statistic was tagged as dubious on December 2021, and I ultimately replaced it with a statistic from sources of significantly higher reliability with this edit on March 2022.

 * Not sure where in the world you are, but as someone who has taught most of his career in several different high schools and colleges, the book is used as an example of one of the first modern novels in translation in upper level English classes as well as in the expected Spanish classroom. It ties in well with European history courses, courses on medieval literature, the development of early modern Romance languages, connections to French tales of Roland, etc.
 * On a somewhat separate note, there are many editions of Don Quixote, just as there are of the Christian Bible. It is likely that these are grouped together (including modernized translations, etc.).
 * Since the high numbers seem to cause concern, I do find the explanation for not including religious texts in the tables followed by the claim that the Harry Potter books are the best-selling of all time to be lacking in NPOV character—better to create a separate chart for those than throw the count under the bus... especially since modern publishing records are easily reviewable and are quite high). If Don Quixote, printed over several hundred years can be included, why not other texts? eleuthero (talk) 04:26, 8 February 2023 (UTC)

Don Quixote with 500 million copies : no reliable, independent sources.
This statement in this article is repeated many times on the internet, but where are the sources?

The claim is supported by a single Wikipédia source, an article by FOXBusiness which states that “The Cervantes Institute, a Spanish public institution created in 1991 to support teaching Spanish and Spain's vernacular languages, have said it is the most translated book after the Bible."

But google searches likes “site:cervantes.es most translated book after the Bible” finds no results.

Extensive research on google and in particular google scholar did not allow me to find reliable sources on the hypothesis of Don Quixote as the best-selling individual book.

I think it would be wise to follow the introduction to the Wikipedia article which states "This list is incomplete because there are many books, such as The Count of Monte Cristo by Alexandre Dumas,[1] Don Quixote by Miguel de Cervantes ,[2] and The Lord of the Rings[3] [...] that lack comprehensive sales figures”.

And therefore to remove the statement of Don Quixote with 500 million approximate sales. Bernhard Brigge (talk) 15:48, 18 March 2023 (UTC)

 * Don Quixote is a 500 year old book. We can know the sales of its most recent editions, but its total sales is a incredible claim.

This page title is inaccurate
This page should be titled: List of best-selling books since 1990. Or should otherwise something that makes it clearer as to the real data contained on the page. As per the presage the requirement of verifiable sales figures means that really only sales since 1990 in western countries are well documented. By default unless one can find a good source, the overwhelming majority of popular novels from before this period are essentially excluded from consideration. Note this causes frequent and constant confusion by people citing this page! 89.2.143.30 (talk) 16:34, 31 December 2023 (UTC)


 * And yet only one of the 6 first books is from post-1990... While most of the sources are recent, many of the books are much older, and the best sources don't restrict themselves to recent sales figures only. The list is far from perfect, but represents a global and timeless perspective as good as reasonably possible for a summary source. While you are free to formally propose a rename, I doubt it will succeed. Fram (talk) 08:48, 2 January 2024 (UTC)


 * You are mostly correct. Figures were centrally collected in the US from the 50s at the latest.  However the numbers of copies of some other books, or at least a lower or upper bound is sometimes known to within a few thousand.  Generally publishers figures are reasonably reliable.  The other huge factor though is the modern mass book market.  Even early twentieth century books tend to report thousands or, exceptionally, tens of thousands of copies printed.  These are dwarfed by modern print runs of best-selling authors, The Silmarillion, back in the 80s had a print run of one million hardback copies, for example.  All the best: Rich Farmbrough 17:13, 4 January 2024 (UTC).

Bible
The opening correctly references that the Bible is the best-selling book of all-time, but then it is not listed in the categories of best-selling books. It should be listed. Keystone18 (talk) 23:00, 22 June 2023 (UTC)

"ideological, philosophical or political nature have thus been excluded" What qualifies as those three things? isn't the anonymous programme at least philosophical in its approach to quitting alcohol, narcotics etc? any autobiography of a political or religious figure is likely to push ideas of some kind, even books on scientific topics like psychological, economics or child rearing has multiple schools of thought so will promote a ideology of a sort. I think that statement essentially removes most non fiction that isn't a dictionary or some other catalogue. — Preceding unsigned comment added by 84.71.80.38 (talk) 22:42, 14 October 2023 (UTC)
 * This sentence is an attempt to provide a figleaf for our uncertainty over these figures, and to avoid having to deal with boosterism, particularly with respect to the Bible vs the Q'ran. Excluding the Bible is also (IIRC) an echo of the Guinness Book of Records entry for this category for decades.  It certainly needs revisiting, but carefully.

Frank Herbert's Dune series
I am not a Wikipedia author, so I leave that to the experts. However, the Dune series should probably be included within the "book series" category. The first book in the 7 book series by Herbert is listed on the page with a sales total of 20,000,000. The others are likely less, but would definitely bump this series much higher as a whole. There have also been maybe another twenty books published within the same universe since the author's death by his son, Brian Herbert and Kevin J Anderson. 184.152.35.170 (talk) 17:26, 25 June 2023 (UTC)

The main page for LOTR states that it has sold over 150 million. If Don Quixotes estimate is included in the list of over 100 million, I don’t see why we can’t also include the LOTR estimate. 2603:6010:11F0:3C0:D80E:D3BA:EFAE:8CD1 (talk) 03:10, 25 March 2023 (UTC)
 * That's explained in the first paragraph of the lead. CodeTalker (talk) 15:23, 25 March 2023 (UTC)
 * There is a dilemma: Don Quixote is quoted in this paragraph as a book that lack comprehensive sales figures and cannot be in the list. But it is still included in the list with a unreliable source...
 * I decide to remove it to be consistent. Let's discuss here if that's a problem. Bernhard Brigge (talk) 12:55, 27 March 2023 (UTC)
 * Thank you. Part of the reason Don Quixote  is mentioned in the lead is that people keep re-adding it.  It is a very substantial book, and the widely spread estimates of 500m copies (present in our article for some time, before the more "modest" 100m) would be equivalent, for example of 150 years of sales at the level of the US bestseller for 1961 (Return to Peyton Place which siled 3.3 million copies that year).
