Reif's the shit P. Everyone hated that book back then, but it's the only thing that rescued me from the horrible teacher we had back then. And by horrible, I really do mean horrible. Stuff like you had to argue that ln(0) was not equal to 0, and that ln(1) was not equal to 1, and then when she couldn't argue anymore, she hand-waved it away "Well it's just conventions anyway" or "Well those are approximations". ln(0)=0 an approximation... Yeah...  

 Anyway Reif is an awesome book, by far the best I've seen on statistical and classical thermodynamics. Very thorough in its treatment of concepts, and never falls back on abhorrent "obtaining this formula is trivial so it is left as an exercise to the reader"-s or the "it can be demonstrated that..."-s.
