People in the comments both here and on the Guardian website seem critical, but I think this is a fantastically fun idea. Sure, you can say it's egotistical, or that it's 'not how history's supposed to work' but if they keep finding critically acclaimed or well-liked authors like Atwood to go along with this, it could be a huge deal - imagine today's readers getting to look forward to a huge compilation of last century's great novelists' unseen works for publication today. And sure where's the harm in a bit of egotism? These authors will now get to fantasise about being part of a collection looked forward to for a whole century. Not that Atwood's work won't survive that long anyway - as has been pointed out, The Handmaid's Tale is already nearing its 30th anniversary!
