What are the best multi-book sci-fi series of all time?

“You can never get a cup of tea large enough or a book long enough to suit me.”
― C.S. Lewis

We can't help but think that C.S. Lewis, he himself having published one of the most popular multi-book series of all time, would approve of the smorgasbord of options available to science fiction readers these days when it comes to multi-book series.  

The multi-book series has the power to absorb us like nothing else. Authors have the freedom to play the long game: to build out worlds with detail and richness the likes of which they simply couldn't if restricted to the length of a standalone or even a trilogy; to build characters of epic proportions that over time, we readers come to know better than our own friends. You ache for it never to end, and no matter how long it is when it does conclude, it will always leave you wanting more.

This week's poll asks for you to ponder multi-book series' containing four books or more, either completed or evolving. Which ones might be considered the very best?  Add your nomination(s) below and then vote on your favorite(s).

We base our lists on the votes and nominations from this blog and our Facebook Reader group, and we want to hear your opinion!

    Without any reservations, I nominate “The Hitchhiker’s Guide To The Galaxy” by Douglas Adams, a marvelous and hilarious trilogy in five parts.

    I see someone dropped the ball. Who was supposed to check for errors like this, before it goes live? So The Foundation Series actually got 70 or more Votes! Way to go.

    Stuff like this makes it hard to take this site seriously. Not only are half of the series fantasy (which is fine, but the title does say “best SF series”), but misspellings abound. Is the Eric series by Michael Morcock anything like the Elric series by Michael Moorcock?

    So surprised, nay SHOCKED, Not to see The Saga of the Seven Suns series by Kevin J Anderson in this list. I’ve been devouring S F for over 60 years and this Space Opera, IMHO is the finest ever conceived…

    The problem with this vote, as I see it, is that a lot of people these days aren’t old enough to have read the classic series written in the 1980’s. I present to you that the Well World series by Jack Chalker and the Saga of Pliocene Exile by Julian May are among the best SF ever written. But not enough people will know these series because they aren’t old enough to have read them when they were released.

    The bobiverse is on there twice.
    And I tried to add Niven’s entire Known Space works (it’s far more than just Ringworld) but I don’t see it.

    I wanted to add Ursula K. Le Guin’s Hainish novels, the Imperial Radch books (starting with ANCILLARY JUSTICE) by Ann Leckie, and the 5-book Quadrail series (starting with NIGHT TRAIN TO RIGEL) by Timothy Zahn, but the form only lets me add one. Would a couple of other people add the other two, please?

      Sharon Lee & Steve Miller’s Liaden Universe is now on the list 3 times. Anne McCaffrey’s Dragonriders of Pern also three times. I hope someone does some cleanup before the totals are announced.

    I wanted to let you know that the Liaden series by Sharon Lee and Steve Miller is on the list twice which will split the votes.

    In addition to double entries there is the issue of folx finding more than one series to be worthy. Frex, I buy books of a certain caliber in hardcover once I’ve read them more than ten times unless they are only available in softcover or ebook. I voted for Lee & Miller’s Liaden Universe(R) series as it’s my top pick but it’s not the only series I would consider for this list and I’ve read thousands of books in my life.

    I’ve loved many of these, and although at least half a dozen deserve to win, my vote goes to the Vorkosigan Saga by Bujold, largely because of the wonderful audiobook performances by Grover Gardner. While not cutting edge, each of these books has been both entertaining and thought provoking. Like others who have commented, I’ve read thousands of books, and could easily vote for many of these, each of which votes I could support for multiple reasons.

    Cool list
    There are some I’ve never heard of, but a lot I have and many I’ve read
    Foundation series could include Robot books
    Dune should include Jihad to Sandworms
    What about Heinlein’s Future History
    Retief’s diplomatic adventures by Keith Laumer or Anderson’s

    ALL the fantasy books MUST be removed. That is a completely different genre. LOTR is better than EVERYTHING on this list by a huge margin and its not even close. But the question is about sci-fi, not fantasy.

    The kuthherian universe is, in my opinion, one of the best science fiction series. It included a great story with a marvellous development throughout the books!

    Expeditionary Force by Craig Alanson is twice on the list, we need only one to not split the votes! Also lots of Fantasy books on the list, they should be removed to make the title correct.
