Search the forums. A couple of us have recommended the motion mountain free online physics textbook.
motionmountain.org
While I haven't looked it over completely yet, it seems to be pretty good for any and all levels of physics.
Otherwise the most commonly used on is written by Serway, Physics for Scientists and Engineers (not sure what version they are on now.)
Check out half.com for used ones.
