Nothing more than slavish copying
From what I understand, case law varies in different countries as to whether a copyright can even exist for this type of thing - in the US, it is not possible as it is deemed to lack originality, whereas in the UK (and possibly France?), it IS possible to copyright a copy.
So one possible solution would be to amend French law to align with US case law (Bridgeman Art Library v. Corel Corp.) on this aspect. So the French ensure that Google's scans are not copyrightable in France, and then agree some sort of partial exclusivity (maybe a right of first refusal for Google to scan books?). Result - the books are free for everyone to access as anyone can simply copy Google's version without issue, but Google still gets what they want
