As you might know, Holla Forums has a very wide and deep library. Some time ago there was a guy who posted hundreds of Holla Forums related books (I have more than 300).
I'm reading through them, but I'd like an advice because there are too many to choose from. In exchange, I'll give my own opinion about the books I've read, so maybe some of you will find something to their tastes.
Up to now I've read:
About the genetic differences between the various human races (with an entire chapter dedicated to the merchants and to how they got their higher-than-average IQ). Very interesting.
The author uses a variety of genetic studies. All the scientists he quotes have of course publicly disavowed the book and its conclusions, but not a single one of them could explain why they're wrong.
Interesting. Doesn't deny that brown people have much lower IQ and tries to explore the connection between productivity/wealth and IQ. Also the Flynn effect, etc.
About the transformation of the UK into a caliphate larva. Interesting when the author talks about the ways the media and the institutions have handcuffed and gagged any critics of Islam. Very biased when she talks about the way poor Israel gets unfairly blamed even though it's an entirely innocent country (not surprising: the author is a jewess).
Mark Steyn is one of the most caustic and funny critics of Islam. Here he gathered lots of his articles and essays that have brought him in front of a so called "human rights" commission in Canadistan for "islamophobia".
Ibn Warraq is an ex-muslim that decided to become an apostate and to expose Islam's brutality and backwardness from the inside. Invaluable read if you want to know exactly what Islam is, what it really says and why it's such a toxic ideology.
Another by Ibn Warraq. The title says it all.
Another by Ibn Warraq that debunks the claims of "orientalists" with a boner for Islam and a tendency to slander the West while defending every muslim atrocity.
A gripping account of WWII where Hitler's merits are for once recognized and he doesn't end up looking like a Disney villain mindlessly bent on world domination.
David Irving has of course been accused of nazism, racism, etc., but his historical informations are accurate and nobody has been able to prove otherwise.
