I read The Complete Robot, which comprises I, Robot, and some other short story collections, including The Bicentennial Man, and loved every bit of it. I must get round to reading the Foundation books at some point.
While I love Asimov's ideas (and his humanism), I find his writing-style fairly pedestrian, and not particularly inspiring in its own right.
The original Foundation trilogy (
Foundation, Foundation and Empire, Second Foundation) is a case in point. For all they're rightly lauded for their scale and vision, they're basically a slap-it-together-and-plaster-over-the-gaps patchup-job of various short stories and novellas which he wrote/published (in non-'chronological' order) over the preceding 5-10 years, and which I didn't think actually hung together all that well. So I was never much inclined to read the later-written sequels/prequels — though I do know that at some point he (or one of his collaborators?) tied the Foundation storiverse to the Daneel Olivaw character (from
The Caves of Steel, The Naked Sun, and
The Robots of Dawn), and hence the 'US Robots' stories.
Mini-rave:
I made an account at Project Gutenberg some years back, and already DL'd a substantial number of early SF/Fantasy titles (from before it was even called that!) by folks like L Frank Baum, Mary Shelley, RL Stephenson, Jules Verne, HG Wells; along with some older classics (e.g. Jane Austen, the Bronte sisters, Conan-Doyle, GK Chesterton, and Twain).
But after following
@gozpel's link above, I just searched 'science fiction' out of idle curiosity, and found a bundle of early 20th-century (SF) authors I had no idea would even be there (though I really should have, given that many of the titles were published >50 years ago now). It looks like they've also got most/all of Burroughs'
Barsoom books, Smith's
Lensman series, and a number of PKDs I haven't read before; plus a few from Fritz Leiber, MZ Bradley, Clifford Simak, Andre Norton, James Blish, and Harry Harrison (I read and loved most of
The Stainless Steel Rat books when I was 11 or 12), among others.
Which is great, because most of what I've been reading over the past couple of years has been stuff off my shelf that I've already read, sometimes 2 or 3 times (albeit over the course of 2 or 3 decades). So, I guess I know what I'll be doing this evening/ week...
