Not a book for the complete beginner, but if you want to progress in Norwegian (which is a diverse family of dialects), this is the most important dictionary you need. Use English-Norwegian/Norwegian-English dictionaries by all means, but there is nothing on the market which comes close to the Green Book. Indispensable: you won't be able to properly translate without it. The only Norwegian-English dictionary to include both Bokmål and Nynorsk, as well as dialect words. If you're serious about learning Norwegian, you can't go wrong with this. No praise high enough.
