Following on from my previous posts on the subject, I've continued to look out for 'classic' SF books that have won awards, appeared on 'Best of' lists etc.
These are the ones I've read over the past year or so:
Dreamsnake by Vonda N. McIntyre - Enjoyably lyrical.
Hothouse by Brian W. Aldiss - Very good, though slightly old-fashioned now.
Planet of the Apes by Pierre Boule - OK, not actually hailed as a classic, and actually rather antiquated even for its time.
The Word for World is Forest by Ursula K. LeGuin - Very good, but not really sure what the fuss is about.
I Am Legend by Richard Matheson - Rather dated.
Do Androids Dream of Electric Sheep? by Phillip K. Dick - I don't know why everyone says this is so good.
According to the GoodReads 'Best Science Fiction' list I've read 52 of the top 100 science fiction novels of all time, which isn't bad. There are, of course, lots of other 'Best of' lists.
