Det Norske Akademis ordbok
There's a new dictionary in town!
It seems to be more extensive, both in terms of words available and in terms of the usage examples and details you're presented with. This also means that some words present may not yet have entered the official dictionary or indeed general usage, so use it wisely.
They also seem to give more suggestions about what they deem to be standard usage in cases where there are several spelling variants and/or declension patterns available. This is a bit of a double-edged sword when dealing with a language so rich in variation and dialects as Norwegian, but I suppose it's helpful from a learner's perspective. It's sure to ruffle some native feathers, though.
For a bit of reading practice, you can read the review of it in Aftenposten, which is overwhelmingly positive, but also touches on the importance of securing future funding for the project.
Tusen takk, det ser bra ut! Jeg liker alle eksemplene og uttrykkene i den nye ordboken! =)
Interessant! Jeg skal bruke den på pc-en min, men det er ulykkelig at de har ikke en mobilapp som kan brukes frakoblet :/
