The Theory of Quantum Information

This is an amazing book...if you are interested in quantum computing and information and have some quantum mechanics under your belt you will want this book. Rigorous proofs of the most important results and a solid introduction to linear algebra...

I am not commenting on book contents which are obviously great. I just don't see the point why this kind of physical condition could be considered "new". The damage at bottom left cover-spine interface is really conspicuous.
