The following is an email message I sent on July 12, 2005 to Professor Jane Ginsburg at Columbia University Law School. Professor Ginsburg's area of speciality is copyright law. Say, for example, you write a book full of quotations and you need to know if you will need permission from the copyright holders to reprint the quotes, you would consult someone like Professor Ginsburg.
Could you ask your mother to send my regards to Bob Strauss? Justice Ginsburg is a great lady -- and not least of all, she has great taste in opera.
