The whole of the extensive 5-volume Finland-Swedish encyclopedia and reference work Uppslagsverket Finland is now available on the Web. Access is free of charge.
The official URL appears to be http://www.uvf.fi/, but this translates to Uppslag.kaapeli.fi/bin/view/Uppslagsverket/WebHome
Access was a bit patchy today, but hopefully these are just teething troubles. Hufvudstadsbladet has a feature on the project.
