Is there a way to study formal systems in general?

I was reading Gödel Escher Bach, and the author explains that mathematics is just an example of something broader: formal systems. So I wonder wether there exists a theory to study formal systems in general, not just applied to mathematics, formal logic or computation, but a general theory which encompasses all formal systems and when applied to those areas give known results. Some book recommendations would be nice.
