oh, thanks I use the quotes on Google every day, but somehow that didn't cross my mind Well ok, that does indeed produce search results to my taste.

But you run into trouble with quotes if there is an initial from a middle name, or some different spelling like Leo Tolstoi / Lew Tolstoy / Lyof N. Tolstoi, or if first/last name are in reverse order like Tolstoy, Lew (which I have yet to see on the Kobo store, but nevertheless).
