As you already have; for which, thanks.

The problem isn't so much copyright restrictions in countries outside the USA as Googles's apparent inability, or unwillingness, to do a few simple checks. In effect, they are making available in America (and presumably other, selected countries) UK material which is out of copyright in the UK, while deliberately withholding it from people in the UK; even when they have obtained that material from UK institutions.

The same problem applies to books cited in the Scottish and Irish threads. So far we don't know whether or not Irish out-of-copyright material is being withheld from users based in the Irish Republic, but it seems likely if Google are consistent in their imposition of restrictions based upon wilful ignorance.
