SR and GR material

jainabhs

Hi
I have a great inerest in SR and GR.As I am in quite learning stage I have started reading docs regarding this from internet.
Presently I am reading a book 'Introduction to special relativity' by Robert Resnik.
Is there any FREE book available on net on this subject or
tell me the way I should approach these theories in order to grasp them better

Any little help will be greatly appreciated as this forum is the only source of it
