A Google post, Finding the laws that govern us, describes a new feature that enables users to read U.S. federal and state court opinions on line.
See: Google Scholar.
You now can use the feature to search by the name of a well-known case, such as Roe v. Wade or Miranda, or you can search by an interesting topic such as the "right to vote", or "freedom of the press".
My suggestion: Digitize legislation and court opinions from many countries in the world and also enable language translation.
This would allow users world-wide to search for topics such as "right to vote", or "freedom of religion" and see and learn how the myriad legal structures of the world compare.
Here is my original SETI research.
