I've actually only read nine out of this list. I'm not sure how interested I would be in reading many of the others. Stories written for children don't really interest me at my stage of life, though I do have fond memories of
The Wind in the Willows (I just would not select it as the best book of the decade). A few of the others I can't muster up much interest in even if the book might be the best of or the first in their genres when those genres just don't interest me (eg Westerns, Crime stories). Tougher call is those by renown authors that are about the neuroses of the wealthy and privileged. I just find it hard to care much about the characters in these sorts of book. Still with recommendations by Issybird and Sun Surfer, I may have to put
The Golden Bowl and
The Wings of the Dove some where on my long TBR list.
