Loads, as it happens - but a lot of that came from the fact that, when I was younger, I couldn't find many new books I liked (unaware of the notion of genre). So I read le Guin's Earthsea Trilogy countless times, as well as McCaffery's earlier Pern novels. Then, as a teen, I read Julian May's Saga of Pliocene Exile repeatedly, and still re-read it every few years, simply because it's that damned good.

I've re-read most of Iain Banks' stuff (sf and 'straight') for the same reason, as with William Gibson and Jeff Noon. In fact, the only probable reason that I don't re-read so often in recent years is that I'm lucky enough to be sent more new material than I have time to keep up with!

Scads and scads. Until some point. I'm not going to post a list, as that probably would be the point where I get banned!

I will point out a trend: The younger I was, the more I tended to re-read something. Why? Well, there was less "genre fiction" around, or less that I had access to, so I tended to re-read what I did have access to.

Later, I would tend to re-read earlier books in a series when a new book came out, to bring me up to date. Now, with the advent of tools like Wikipedia, it is easier to find a synopsis of earlier books to refresh the memory.

So I do re-read books these days, but the number has dropped. A lot. They tend to be books I have not read since I was a kid (for example, I'm currently re-reading Andre Norton's "They Shall Have Stars!") or books I have not visited in many years that I'm trying to get a fresh perspective on (for example, I'm re-reading Gene Wolfe's "New Sun" books and may--may!--tackle Stephen R. Donaldson again. May!)

One of my resolutions this year was to reread one of my favourite sf novels each month. And so far I've managed to stock to it. I've been writing up the experience too. Here's the first post.

Posted by Ian Sales on Tuesday July 24, 2007 at 1:51 PM at 1:51 PM

Richard Brautigan's A Confederate General from Big Sur and PKD's 3 Stigmata usually once per year. They make a good read together for some reason.

I've done Dhalgren quite a few times, because you can always get a few new nuggets out of there...

Posted by platyjoe on Tuesday July 24, 2007 at 1:54 PM at 1:54 PM

Only the Narnia books several times.

Posted by SciFiChick on Tuesday July 24, 2007 at 2:01 PM at 2:01 PM

I re-read "Dune" at least every 2 years and the "Lord of the Rings" almost as much, Asimovs "Foundation Series" and Larry Niven's Motie series(most likable aliens ever) but I find that I tend to skip to my favourite chapters and/or passages never really doing a complete reading

Posted by Jahluv on Tuesday July 24, 2007 at 2:09 PM at 2:09 PM

I re-read the LotR trilogy once a year around this time of the year (finished it a couple of weeks ago). Done it for the last 21 years now.

I've re-read the Honor Harrington series about 6 times from Basilisk Station to At All Costs.

Back when I was younger, I re-read The Godfather several times (I know that,s out of genre, but it was a book that I re-read obsessively when I was in my late teens)

Asimov's Foundation trilogy several times, also back then.

I actually *have* to re-read stuff, because I read way too much for my wallet to support it (5-8 books a week), and I don't feel well if I haven't read anything at the end of a day, something is missing So...there's lots of good stuff I've re-read.

Also, when there's a new book from a good series that gets published long after the previous one comes out (like happened with Flint/Weber's Belisarious Saga), I re-read the whole series before reading the new book, to get into the I-so-want-to-read-this-book mood.

Also, I think re-reading books as you grow older gives you new perspectives on things...I'm amazed that Tolkien managed to write something that I've been able to appreciate and love for 21 years, even if for the last 4 or 5 there *are* parts that I skip (those long-ass descriptions do push my patience now, unlike when I was younger), while I'm sadly disappointed that most of Asimov's stuff has lost its luster as I've grown up (Nightfall is still one my top 10 of all times, tho), which makes me not recommend it to older friends...but as soon as my nephews hit their teens, they are getting the Foundation trilogy as a gift from me.

In other words, re-reading is something that happens to me quite often...and most of the time it's very enjoyable.

Posted by Vox on Tuesday July 24, 2007 at 2:20 PM at 2:20 PM

I don't re-read much, but I had to go back and read "Perdido Street Station" and "The Scar" by China Mieville again, mostly because the first time my mind was busy being blown, and it took a second pass to properly absorb everything. Superb books, both of them.

Posted by Michael on Tuesday July 24, 2007 at 2:27 PM at 2:27 PM

The Chronicles of Narnia, The Dark Is Rising Sequence and Tim Powers' On Stranger Tides and The Anubis Gates.

There are others, but these are the ones I've reread the most.

Posted by Misty on Tuesday July 24, 2007 at 2:33 PM at 2:33 PM

I've read the LotR 15 or 16 times. I've read the Narnia Chronicles 5 or 6 times. I've read Les Misérables twice (even though it's not Sci-Fi) and am looking forward to reading it again in a year or so.

Posted by Bruce on Tuesday July 24, 2007 at 3:16 PM at 3:16 PM

I wish I had time for re-reads, not enough to get through all the good stuff out there first time round.

Posted by Ed on Tuesday July 24, 2007 at 4:01 PM at 4:01 PM

Of Mice and Men and The Hobbit 5 times. The Lion, the Witch and the Wardrobe twice.

Blessings
Richard

Posted by Richard Novak on Tuesday July 24, 2007 at 4:26 PM at 4:26 PM

Back in my long lost youth, I never bought a science fiction book until I had read it at least twice, and knew that I would reread several times over again.

The most reread book in my collection is LORD OF THE RINGS, which I read on average once a year every year between elementary school and law school.

In my day, no, there was not that much 'good stuff' out there waiting impatiently to be read. There was nothing like Tolkien.

Posted by John Wright on Tuesday July 24, 2007 at 5:08 PM at 5:08 PM

I'm too far behind in my reading (and too advanced in age) to justify (at least in my mind) rereading books. However now that I have a hour one-way (two if there's traffic) commute I have begun a project of "rereading" most of the classic SF canon as audiobooks. I did the Foundation books, plus Asimov's prequels and sequels in "historical" order rather than order of publication. Did the same with the Dune books, reading the Anderson/Herbert prequels first, then moving onto the Herbert books proper.
Gateway, Dispossessed, Childhood's End, Canticle for Leibowitz, About seven Heinleins, the Rama books, and The Gods Themselves have all kept me company in the past four months.

Posted by Jeff P on Tuesday July 24, 2007 at 5:41 PM at 5:41 PM

I tend to reread my favorites every few years.

A very partial list:

DIASPORA by Greg Egan

THE NIGHT'S DAWN TRILOGY by Peter F. Hamilton

EXULTANT, TIMELIKE INFINITY, MANIFOLD: TIME, MANIFOLD: SPACE, and
quite a few others by Stephen Baxter

All of Lawrence Watt-Evans ETHSHAR novels.

THE HYPERION SAGA by Dan Simmons

THE HARVEST by Robert Charles Wilson (and most of his other books)

Posted by DBE on Tuesday July 24, 2007 at 6:16 PM at 6:16 PM

Starship Troopers a couple of times.
Huckleberry Finn at least three times. Gets better each time.
Glory Road. Read that twice in high school
Ender's Game. Couple of times.

Posted by Ed on Tuesday July 24, 2007 at 7:39 PM at 7:39 PM

I re-read pretty compulsively, but mostly outside of sf, since I've only recently gotten into it. I've read LOTR, the Hobbit, and all the Harry Potter books multiple times. I've read The Time Traveler's Wife several times as well. Most of the books on my shelf, actually, I've probably read two or three times.

I love re-reading, but I'm starting to feel guilty about it, since time I spend re-reading I don't spend reading new material. It's a balance, I guess.

Posted by Claire on Tuesday July 24, 2007 at 7:46 PM at 7:46 PM

I would love to re-read, but I just can't bring myself to. As many of you, I feel there's just too much out there I'll never get to. I keep telling myself I'll go back to books when I'm old and retired, but I'll probably still feel guilty. The only book I can remember re-reading is "Franny and Zooey."

Some books I'll want to re-read:

Yes, I Can - Sammy Davis Jr.
The Sheep Look Up
A Tree Grows in Brooklyn
Ender's Game
The Martian Chronicles

Posted by Anonymous on Tuesday July 24, 2007 at 8:19 PM at 8:19 PM

Lord of the Rings 3 or 4 times
Dune twice
1984 two or three times
The Talisman by King/Straub 3 or 4 times
The Stand, The Eyes of the Dragon, The Gunslinger by King 3 times each
A Song of Ice and Fire twice
Gardens of the Moon twice
Memory, Sorrow and Thorn twice
The (first) Chronicles of Thomas Covenant, the Unbeliever

Posted by Rob B on Tuesday July 24, 2007 at 8:40 PM at 8:40 PM

I read Neuromancer and Starship Troops each about once a year. Both are short enough that I can pick them up when I do not have another book in line to read.

Posted by Greg on Tuesday July 24, 2007 at 9:02 PM at 9:02 PM

LOTR, of course, and The Hobbit.
Narnia.
Flashman Papers (George MacDonald Fraser; historical fiction).
William Forstchen's Lost Regiment series (Civil War soldiers on alien planet fighting cannibalistic "horde" warriors with allies from several historical Earth periods).
To Kill A Mockingbird.
The Razor's Edge.
Tarzan books (and everything else by Edgar Rice Burroughs).
Anne Rice's Vampire books.
Conan (Robert E. Howard).

Posted by Greg Lindenberg on Tuesday July 24, 2007 at 10:35 PM at 10:35 PM

Forgot:
Frankenstein.
House of the Seven Gables.

Posted by Greg Lindenberg on Tuesday July 24, 2007 at 10:37 PM at 10:37 PM

Like many others, I hardly have time to finish the backlog of books in my cupboard, much less to re-read any of them. However, one book that I do keep going back to is the Hitchhiker's Guide to the Galaxy.

Posted by Aditya on Wednesday July 25, 2007 at 1:12 AM at 1:12 AM

-LOTR, The Hobbit, The Silmarillion
-the Hyperion books by Dan Simmons
-The Years of Rice and Salt by Kim Stanley Robinson
-The War of the Worlds
-the Foundation books and Nightfall
-Dune
-Neuromancer
-The Martian Chronicles
-The Tower of Beowulf by Parke Godwin

I agree with some of the previous comments that Foundation and Dune have lost their lustre over the years.

While it is tough to fit in a re-read with the heavy load of new books, I try to do at least two a year just to remind myself why I love particular stories. If they can stand up to the test of a re-read, they're worth re-reading again in a couple of years.

Posted by bloginhood on Wednesday July 25, 2007 at 1:20 AM at 1:20 AM

I have re-read all the Harry Potter books. The goblet of fire in particular, several times, and than I bought the audio version and listened to it a couple of times. I have re-read the Foundation and the Foundation and the Empire several times as well. As for nonsf I re-read the Runaway Jury, A Time To Kill, The Brethren and The Firm from John Grisham several times. Non-fiction books include aviation and course books.

Posted by General X on Wednesday July 25, 2007 at 2:08 AM at 2:08 AM

every 2-3 years: catcher in the rye
lord of the rings
lord of the flies

three times that i recall: foundation trilogy
1984
animal farm

Posted by steve on Wednesday July 25, 2007 at 2:13 AM at 2:13 AM

First post here, but seeing as how I reread quite a lot I thought I'd post - although most of mine have already been mentioned already

Hyperion - Dan Simmons
The Last Legends of Earth - A A Attanasio
Lord of Light - Roger Zelazny
A Song of Ice & Fire - George R R Martin
Chronicles of Thomas Covenant - Stephen Donaldson

And when I was younger

All the Narnia books - C S Lewis
The Dark is Rising Sequence - Susan Cooper (though I want to read that again soon)
And the Belgariad & Mallorean - David Eddings

Posted by Daemon on Wednesday July 25, 2007 at 6:00 AM at 6:00 AM

I haven't re-read much, especially in recent years. Too many new books to read!

Who's "Orison" Scott Card? Is he Orson's baby brother?

Posted by PeterY on Wednesday July 25, 2007 at 8:03 AM at 8:03 AM

The second time I read LOTR I stopped in the middle of The Two Towers, which let's face it, is very dull.

I'm just trying to keep up with the new books on my shelf. Haven't reread anything for ages. However I'd love to reread SnowCrash and the Sprawl trilogy.

Posted by James on Wednesday July 25, 2007 at 8:53 AM at 8:53 AM

Iain Banks' Culture stuff.
Hyperion and The Fall Of Hyperion.
Startide Rising.

And of course, the Sten series, every so often.

Easy question:
Stinger by Robert McCammon
Damnation Game by Clive Barker
and any collection of HP Lovecraft stories

Posted by DarkIcon on Wednesday July 25, 2007 at 12:30 PM at 12:30 PM

In the past 10 years, the only series I've been able to read more than once is George RR Martin's "A Song of Ice and Fire" series, currently waiting on Book 5.

I've read the first 4 books half a dozen times each.

Posted by Michael Natale on Wednesday July 25, 2007 at 7:31 PM at 7:31 PM

Like others, I've re-read some books because there were no others to read at the time, in addition to liking them a lot too.

Lord of the Rings Trilogy - 2 times
The Foundation Series - 2 times

That's about it, there are a couple that I'll re-read when I have the chance again though, like The Etched City and the Silmarillion.

Posted by Tony Geer on Wednesday July 25, 2007 at 10:48 PM at 10:48 PM

Hmmm.. might be easier to count the books I haven't re-read. I get through several books a week, and usually one of them is an old favorite.

My family has a tradition of reading Dicken's Christmas Carol out loud together every year. It got so that while we all knew the book exetremely well, we also kept seeing new things in it.

Posted by Joi on Thursday July 26, 2007 at 6:31 PM at 6:31 PM

When I was a kid (5th grade), I must've read the Narnia series a half-dozen times. Read it again when the movie came out and realized it didn't hold up well (for me at least).

I don't know how many times I've read Zelazny's Amber series; probably verging on double digits (at least for the first five). Same for the Hitchhiker's Guide to the Galaxy (at least the original trilogy). There's something about them that keeps drawing me back, and I seem to find new bits each time I read them.

I've read The Hobbit probably five or six times, and the LotR trilogy three or four times.

I've read the first four Harry Potter books twice; read them again when book 5 came out, but didn't feel I needed the refresher for books 6 and 7.

Posted by Bill on Friday July 27, 2007 at 11:52 AM at 11:52 AM

Gosh, lots.
Dune, I Am Legend (several times), The Man Who Fell to Earth, The Forever War, A Canticle For Leibowitz, 2001.
Plus a bunch of Philip K. Dick: VALIS, Ubik, Three Stigmata of Palmer Eldritch, Divine Invasion, Eye in the Sky, Time Out of Joint, Transmigration of Timothy Archer, A Scanner Darkly, A Maze of Death, and probably a few more.
Then there are the ones that I want to read again, but haven't yet, including Rendezvous With Rama and the Time Traveler's Wife.
And I can think of three that I didn't like the first time around that I gave second chances to: Ender's Game (better the second time, but I still think the sequels are much, much better), Starship Troopers (still detest its politics, but it's a good read) and Stranger in a Strange Land (which I probably liked even less the second time through).

Posted by Gabriel Mckee on Saturday July 28, 2007 at 8:40 AM at 8:40 AM

From eighth grade to about age 25, I used to read DUNE once a year. Now I just read it every four years or so.

Off the tope of my head, my favorite readovers are: THE GYPSY by Steven Brust and Megan Lindholm (Robin Hobb), BONE DANCE by Emma Bull, and WHEN GRAVITY FAILS by Alec F. Effinger.
