There are still a couple shelves at my parents' house in my old room (which I left for college 20 years ago) full of double rows of ST novels from Pocket Books.
Anything by Heinlein, Eddings or Pratchett whilst I was growing up. I don't think I've actually veered very far from there if I'm honest :)
The LOTR books were read to me when I was very young. I also loved the Narnia books as well as David Eddings books when I was younger (and still to this day).
I remember loving The Prydain Chronicles by Lloyd Alexander and Robin McKinley's The Hero and the Crown and The Blue Sword. The L'Engle trilogy. In high school I plowed through a bunch of Piers Anthony Xanth books my uncle dumped at our house. And I got really into the Pocket Books ST and ST:TNG books then too (so much so that I won a mug in a trivia contest at a con by answering a question about a detail from one novel). Oh, and I got myself a subscription to Asimov during high school and devoured those monthly, picking up authors like Allen Steele from his short work and reading his novels. And I think I read the Foundation Trilogy but what I really remember is discovering a radio play version late at night on a public radio station at the bottom of the dial and listening to it after I was supposed to be asleep on my first Sony Walkman.
I read The Hobbit in middle school and it was the first book i read that i actually enjoyed. Later I discovered Douglas Adams, which remains one of my favorites to this day
I can't believe nobody's mentioned The Hitchhiker's Guide To The Galaxy! I read it (the four volumes) twice. I'm sure the British humor and SciFi affected me.
I've still never managed to read the books. Something about them being so thin always put me off :S
I did used to stay up late at night and listen to the BBC radio play of the series though and loved every second of it.
Also check out his Dirk Gently series, those are pretty hilarious too
Absolutely. Hitchhiker's Guide were hilarious, although I think I heard the radio series first. The name Zaphod Beeblebrox is lodged somewhere deep in my mind. I actually read some of the 'older' sci-fi, like Jules Verne as well.
For fantasy, Lord of the Rings, Narnia, and later Xanth books were most memorable (for a young boy!), and the Pern books. But I read anything in which the characters had a sword.
Um...I don't think that was available when I was growing up, at least not in the states. However, one of the first things my youngest son asked Siri (the iPhone) was "What is the meaning of life?" hoping for the right answer.
Wells, Verne, Asimov, Clarke, Bradbury, Tolkien, Donaldson
Jules Verne, HG Wells "War of the Worlds" (I had the same copy of this that the Doctor had in one of the older series (I think it was Jon Pertwee)) Asimov, Heinlein ( I loved "Stranger in a Strange Land" and "The Moon is a Harsh Mistress"), Larry Niven ("Ringworld" ruined my chances of passing Engineering :)
