I am not entirely sure what you are asking, so I will try to cover all bases.
Here is a list of the requirements for a undergrad degree in physics at MIT:
http://web.mit.edu/physics/current/undergrad/major.html
Here is the MIT course catalog: http://web.mit.edu/Physics/subjects/index.html
Here is just a list of physics subjects, if that is what you were looking for:
https://en.wikipedia.org/wiki/Branches_of_physics
This is a research website. Under the physics headline, you will see the name of most of the fields that are currently active research-wise:
http://arxiv.org/
Then, if you see a subject that seems interesting, you can just google "Book in <subject>". You can also try "physics stack exchange <subject> book", because someone has probably asked for recommendations before.
Also, I think if you look through
this other thread by ZapperZ (which I think is the basis of Greg Bernhardt's link), you will find several suggestions about courses to take, books, and what is generally expected of someone who has an undergrad in physics. I actually think that is covered on the first page when it says you should be able to do well on the physics gre. So, seeing what topics are tested on the subject test may also be beneficial, but again, I am not positive if any of this is what you were looking for.
