I read Introduction to special relativity by Robert Resnick. It is a beautiful book as an introduction. I got insights and intuition in special relativity. I want to learn special relativity at a more deeper level. Please recommend some books/ research papers for special relativity?
"The Meaning of Relativity" - A.Einstein. This will help you make the connection between SR and GR - tensor notations, etc - since deeper then special relativity is general relativity, but I suppose you wanted to say "more general appliance", "arbitrary directions", etc.
Feynman lecture - volume 2 - Feynman Lectures (there is also volume 1 [and 3] - as good as 2nd)
Relativity - MIT Course 8.033 (very good course, treating more advanced topics too and cosmology/BigBang stuff)
Special Relativity - Video Lectures - L. Susskind (and if you want more you could always get to see his GR lectures; if that won't be enough you can get to see his String/M-theory lectures; if that won't be enough you can get his ER=EPR lectures)
Classical Electrodynamics - Robert G. Brown (Duke University Physics Department) - I found this useful on several occasions (ex: when dealing with electromagnetic tensor transformations)
Also when dealing with arbitrary directions this derivation is quite nice.
"Special Relativity: An Introduction with 200 Problems and Solutions" by Michael Tsamparlis covers a lot of stuff and goes in depth.
It can also be used as a "SR cookbook", because if you need some SR formula, you will probably find it there. If not, then you probably won't find it easily in some other SR textbook.
There is an old book by Max Born, called Einstein's Theory of Relativity which explains the Special Relativity in great detail without any advanced mathematics and a little bit of General Relativity.
It is suitable for those who has not yet started to physics degree or will not, but would like to understand the theory in a deeper and mathematical manner. Then one can go for a more advanced textbooks by learning real calculus and vector algebra/calculus and so forth.
My favourite books on special relativity, both advanced and with a strong geometric flavour, are:
É. Gourgoulhon, Special Relativity in General Frames: From Particles to Astrophysics, Springer, 2013.
G. L. Naber, The geometry of Minkowski spacetime, Springer, 2010.
They both require a non-basic knowledge of linear algebra.
