Hello,
I find llm-guide really useful. But you could add more titles regarding the llm fields such as "it law, ip law etc" You could search specific law fields without looking in to country titles.

There's actually already a way to do this.

Go to a region (eg http://www.llm-guide.com/usa ) an click on "concentrations" under the tag cloud.
