Surprised me too, but most listed books are from traditional publishers, like Elsevier, Springer, O'Reilly, etc. I expected that they'd just ignored books from No Starch, but then there is Randall Hyde's "The Art of Assembly Language".

I think (/ hope) that the later was picked up by being homed on GitHub - https://github.com/rust-lang/book

I’m sure Steve Klabnik will eat me alive, but having read both I think it’s the better book!
