Elaborated with the help of followers on Twitter (oops! Sorry, yes I'm also still there!) here are ten books per decade to catch up on the best #scifi and #fantasy classics.
@panoramix Yes, Thanks, I'm pretty proud of the list we have achieved. And since it was a collaborative list, people voted for stuff I never read: there are about a dozen I need to catch up too!

@themiddleshelf Nice list, and I still have a lot of catching up to do.
