Laeticia,
I'm also not new to the list, having subscribed about a year
ago. I've started studying Old Norse a few times, but get
distracted by other projects. I do read French and to a lesser extent
German.
I
understand that modern Icelandic is not extremely different from Old Norse.
So I have also looked for some English books on modern Icelandic. Found a
book in French that introduces modern Icelandic. To me at
least, it is more
"user-friendly" than the English books. So if by chance you speak
some French, you might find it helpful.
The book is called
Parlons islandais and is available at the French Amazon
site.
