So now that's out of the way, I do think it's pretty ignorant to specifically reply to a thread about JD Salinger and Catcher in the Rye just to say you've "never heard of him let alone the book" (or not having read it, which wasn't even mentioned). I'm not especially fond of American literature in general, but Catcher in the Rye is a fairly seminal book no matter how you look at it.
I was reading a news story the other day about how today's youth don't find it relevant to their lives, and it's hard to imagine that things have changed THAT much since I was in High School. I don't know any High School kids anymore, but I did wonder how much of it was just sensationalism for the sake of the story.
Back to the topic of the thread, I'm pretty excited at the prospect of those 15 unpublished manuscripts, assuming they exist and ever see the light of day.
