If you are interested in information about rawls theory, I suggest you start with Credo, a database that is a great place to start your research. The search box is found on this page http://lib.sxu.edu/background
I read Rawls was a philosopher and political theorist. I then went to this page... http://lib.sxu.edu/philosophy
We have books about Rawls in our catalog and there are more in IShare. enter his name john rawls to get books about him. then narrow your search with his name and add the term justice for books that include the word justice in the title or somewhere in the book's record.
The next place I would look is the database, Academic Search Complete. To begin your search you could enter this in the box
rawls and "theory of justice" and then on the left you will see other ways to narrow your search. Plus you could add other terms.
Since you didn't provide me with more information, I don't know what you are doing. This is a good start. If you have any questions you can contact me.
