This change seems to be heavily oriented towards the travel sector (which Google apparently seeks to dominate both on its own account and in coordination with TripAdvisor). I see high quality sites with exact matches going down on the first page and disappearing completely in a few cases. In contrast, in our other sector, rare books and maps, none of our sites nor those of our competitors have changed position.
