Thanks to the researcher. This generally gives me a sense of what I
was dealing with, although it did not absolutely answer my question
(hence 4*s)

The last 4 Requests for Clarification that I put in were ignored. I want a refund.

Thanks for your thoughts.  I whole-heartedly disagree that "Google is
lawfully exempt from litigation unless they knowingly allow
copyrighted works to remain posted after they have been made aware
that an infringement is taking place."  If there's anything that can
be said about the state of litigation in this country, it is that no
person, company, organization, or anything else you can think of, is
exempt from litigation.  And once you're in litigation, anything goes.
 The law is not absolute, and any judge can, as the title implies,
make a judgement call.

Anyway, thanks for your comments, though you didn't really answer the
first question, that is: HOW DOES GOOGLE LIMIT ITS LIABILITY.  i.e.,
what steps does it put in place.  You say it puts the onus on the
researcher...how?

This is exactly what I was looking for!  Just enough depth to give me
something of an understanding, and plenty of links.  Arthur Robbins is
exactly what I wanted, particularly the Subway series.  Thanks.
