It's interesting. However, I'd say half of them I wouldn't of had on a list of "Must Read". Having said that I have 60 of the books on this list. Still, it's always interesting seeing these list for what is & is not on the list.
Assembling the list of the most essential science fiction and fantasy books is a huge undertaking, but Amazon has tackled it. And their list is not bad. Good mix of old and new, and enough different types of book to please almost anybody.
