Some portions of the Koehler article make it very clear that he is
well aware that 'snippets' are not the issue:
"Yet many of us are uncomfortable with the Google plan. It looks
like an unfair taking of intellectual property. Google tells us
that it will only serve up snippets. But we need to remember that
Google is serving up snippets from the whole thing copied from
the original. That "whole thing" may well be a copy of a work
still in copyright." (from the penultimate section of his piece
"I am not a lawyer")
Perhaps the most troubling aspect of the 'opt out' solution
proposed by Google is that it has operated as though it has the
sole right to determine the 'opt out' procedure. That cannot be a
fair and reasonable solution; its a nightmarish prospect for
rights owners since there could be any number of different
methods of secondary digitisation which involve a myriad of
different 'opt out' protocols. At least the robots.txt (which was
designed for web sites not for printed materials) is a
convention which is general and accepted by the industry.
I have no doubt that there will be scores of different ways of
digitizing texts in 20 years time and lots of digital formats.
When digital copies are easily and trivially made from physical
copies an 'opt in' permission has no chance of prevailing (see
the fate of 'opt in' for recorded music in the last 30 years). In
such circumstances an opt out procedure is going to be preferable
for publishers and authors to an 'anything goes' principle. But
the opt out procedure must be principled, fair and balanced.
