Copyright authorization request

First of all I would like to congratulate you on this forum. It's a great tool.

I am a student at the University of Arizona College of Law. I am getting a Master's degree in International Trade Law.
I am writing a paper on "The Amendment of the Letter of Credit", under
the supervision of Professor Boris Kozolchyk. I have found your
discussions on this subject to be quite interesting, since they cover
issues that are real in everyday ussage of letters of credit. I would
like to refer to these issues in my paper.

I would like to
get permission to use your discussions on amendments of letters of
credit. How could I get your authorization? Who could I talk to?

Thank you!
