Old Norse Text Linguistics?

Well, i have already posted this about a week ago (if more or less
i'm sorry - i'm lousy when it comes to this...) but i got no
response.
It's does not seem to make any sense that there are so many texts in
old Norse, such a vast corpus, yet it seems to be extremely hard to
find a good text linguistics book, or a structural (descriptive)
grammar of old Norse.
other languages, about the same regarding corpus size, (e.g Coptic)
have a vast amount of linguistic literature. yet old-Norse seems to
me, have been ignored for some reason. strange.
can someone send over some bibliography (whatever language)?
perhaps there is something from the linguistic circle of Copenhagen?

thanks.
