There's also an O'Reilly book available for preorder, authored by Mozilla's Jim Blandy: http://www.oreilly.com/pub/e/3291?reminder

Packt also has a book on Rust which should be available soon, though I've never heard of the author and so I can't speak as to the quality: https://www.packtpub.com/application-development/rust-essent...

There's also this draft of a Kickstarter for a book on Rust, though again I've not heard of the author before: https://www.kickstarter.com/projects/1712125778/1409335994?t...

Oh, and there's at least one more book in the pipe, and this one in particular is being developed by members of the Rust community... expect an announcement soon. :)
