Which Book Is Best for Learning Relativistic Quantum Mechanics?

[ziad1985]

What would be a good Book to learn it?
I did liltle search On amazon ,https://www.amazon.com/s/ref=nb_ss_...Go.y=19&Go=GoGo.y=19&Go=Go"&tag=pfamazon01-20, I got ton of results.
Any advice on what would be a good one?

My impression is that modern textbooks focus on quantum field theory, having some introductory chapters about relativistic quantum mechanics that explain the problems and motivations that lead to quantum field theory, rather than treating only quantum mechanics of relativistic particles, as presented for example in Bjorken & Drell. I am by far no expert, but I could only mention Bjorken & Drell for pure relativistic quantum mechanics. On the other hand I could tell you lots of excelent references for quantum field theory such as Ryder's, Zee's "QFT in a Nutshell", Peskin & Schröder's, or the more advanced first volume by Weinberg.
