That answered the question all right:
Apart from the US dollar and, of course Pound Sterling, currencies for which LIBOR is a significant reference rate currently include the Swiss Franc, the Yen, the Canadian dollar and the Danish Krone...
It's a reference rate published once each day, so it's derived from the market activity between banks in each country and used as a benchmark for contracts and so forth.
Hooray! We're smarter now.
