Further to the recent entry on The web as dictionary, a Swiss site has a form for multilingual web searches for translators.
This will find sites with more than one language. You choose a combination of EN with DE, ES, FR, IT, NL, PT or SV, and you have further choices – for instance, in German you can choose sites in DE/CH/AT – but apparently not individual countries. Thus if I were translating from Swiss German, I might search for CH sites or UK sites (the UK option isn’t given).
