I love time travel novels.  Suggestions?

End of Eternity by, I beleive, Poul Anderson.  Also Time Patrol

To Say Nothing of the Dog and Doomsday Book, both by Connie Willis

The Door into Summer by Robert Heinlein.  You might also try a couple of his short stories about time travel - All Yo9u Zombies, and By HIs Bootstraps

Timeline by Chrighton (sp)

I know I could think of others, but I shouldn't have tried to answer this at 1 a.m.

The Time Traders by Andre Norton.  If you like it, it is the first book in that series.

I second the advice above to read The Door into Summer by Heinlein. It is a wonderful tale.

Thank you both for your suggestions.  This should keep me busy.  I asked this question under several different genres.  It's interesting how I got completely different recommendations from each genre.  If you think of others t travel books, let me know.

End of Eternity is Asimov (makes it a better book in my boat).

Poul Anderson did write the Time Patrol series of short stories, I recommend getting one of the omnibus's (he wrote another short story in '95 which is only in the last omnibus(2006) if you are a stickler for completeness).  It concludes with his novel Shield of Time.

As for my own suggestions, you can't forget "The Time Machine" by HG Wells.

In addition, I'm trying to remember who the author was (my mind says either Zelazny (his style) or Niven (his stand on time travel)), but there was a book of related short stories spoofing on the Time Patrol (the main character goes "back in time" and brings back aliens from other dimensions, dragons from fantasy worlds etc to be placed in his king's zoo).

Also if it helps here is a link from ISFDB.

The list isn't complete but is pretty good otherwise.

The Accidental Time Machine by Joe Haldeman

In my opinion, the original time travel novel is still one of the best - A Connecticut Yankee in King Arthur's Court by Mark Twain.

Second the recommendation for the wonderful Doomsday Book, by Connie Willis. Even better if you have read her short story Fire Watch first. To Say Nothing of the Dog is also excellent but much more light-hearted. And her new books, Blackout and All Clear, are also time travel.

Time and Again, Jack Finney - one of the good ones. Made into the movie Somewhere in Time with Christopher Reeve. It has a sequel, From Time to Time, although I didn't find that one as compelling.

The Man Who Folded Himself, David Gerrold, one of the SF classics. It's a little bizarre.

Replay, Ken Grimwood; excellent story although not strictly time travel - the protagonist dies and comes back to existence as his younger self, having to relive his life again, and again, and again although knowing the future he can make changes each time.

Cretaceous Sea and Sea of Time, Will Hubbell; a tourist group goes back in time to check out the dinosaurs. Of course something goes wrong. 

If you can find it - The Dechronization of Sam Magruder, by George Gaylord Simpson - the diary of a guy who accidentally sends himself back to the age of the dinosaurs, by himself and no rescue possible.

I'm currently reading "Time Travelers Never Die" by Jack McDevitt. I've read 50 pages so far and it seems like fun. I'll post it when I'm done.

  I just finished The Breach and Ghost Country by Patrick Lee. Both with time travel elements, and both fast paced fun stories.

Another one you might try is "Project Pendulum" by Robert Silverberg. I just received it, but haven't gotten to it yet.

Pastwatch: The Redemption of Christopher Columbus by Orsen Scott Card. Dumb title, excellent book.

Here is another that is very entertaining, Eridahn by Robert Young.  And it is currently available here. I like it enough to have read it more than once.

"In 1998, Jim Carpenter drove a time machine for a living. and his last job seemed simple enough: go back in time 74 million years and find out how a human skelton got mixed up with dinosaur bones --- millions of years before that could possibly happen!

But then Jim found two frightened, well-dressed kids hiding from a dinosaur. They claimed to be the prince and princess of Mars! Well, the boy claimed they were. The girl, it seemed, didn't speak to commoners."

I 2nd Pastwatch by OSC.

No one's yet mentioned Mammoth by John Varley, it's like a sci fi thriller.

Cheers, Margaret
