Announcing Goodreads Personalized Recommendations

Posted by Kyusik Chung on September 15, 2011
Goodreads was founded with the mission to get people excited about reading. And the key to getting people excited about reading is to help them discover books that they’ll love, and then to enable them to share their thoughts and experiences with friends.

Today, Goodreads launches a new personalized book recommendation engine. It takes recommendations to a new level of sophistication by analyzing both books and, more importantly, the people who read them. It’s the Netflix of book recommendations.

Finding a great book recommendation online has been a hit-and-miss affair to date. We’ve all experienced the unhelpful suggestion to read another book by an author we already love. And how about the dreaded impact of buying gifts on Amazon only to have irrelevant book recommendations come up for months afterwards?

Earlier this year, Goodreads purchased a company that had built a very sophisticated book recommendation system. Today, after months of hard work, we’re ready to provide you with book recommendations that take into account what you like and don’t like and what certain books mean to you.

To get started, rate at least 20 books (and rate much more to get even better recommendations). Categorize your books in custom shelves that reflect what the books mean to you. Then explore your recommendations. We apologize for the impact this will have on the size of your to-read shelf.

How Goodreads Recommendations Work

The Goodreads Recommendation Engine combines multiple proprietary algorithms which analyze 20 billion data points to better predict which books people will want to read next. It maps out the connections between books by looking at how often they appear on the same bookshelves and whether they were enjoyed by the same people. On average, Goodreads members have 140 books on their shelves. With this information, the engine learns how your tastes are similar to or different from the tastes of other Goodreads members.

So, a big part of the secret sauce is…you, the Goodreads community. The Goodreads community is almost six million members strong, and you’ve added a combined total of 190 million books to your shelves!

Take best-seller The Help as an example: Goodreads members have added over 175,000 ratings of the book and over 40,000 reviews. In comparison, Amazon has, to date, less than 4,500 reviews and ratings.

But it doesn’t end with raw numbers. Goodreads members have put The Help on bookshelves called Historical Fiction, Friendship, Racism, Women’s Fiction and Cultural > African American. You can see how this book means different things to different people. If you’re approaching this as Historical Fiction and have enjoyed The Guernsey Literary and Potato Peel Society and A Tree Grows in Brooklyn, then a great recommendation for you is These Is My Words. With Amazon, the focus is on other best-sellers so someone buying The Help would get recommendations for books as diverse as Water For Elephants, The Hunger Games, and One Day.



We welcome you to try our recommendations on for size. Compare them with anything else you’ve relied on online. Then tell us (and your friends) what you think. We think you’ll be blown away, and that you’ll meet your next favorite book on Goodreads.

Shanelle Sorensen I love this new system! I've only read one of the books it recommended for me, but I absolutely loved it! And the other books seem spot on. I'm so excited to read more of them!


message 204: by Susan (new)

Susan This is more like Amazon or Netflix, but the whole idea of the GR "community" is to "talk" to other readers. The Recommendations encourage us to skip that step.

I don't think so, personally. If anything, I think it can promote/supplement discussion of different books. I already see where, in certain cases, it could allow people to say "I saw this book on my rec list, have you read this book too? What do you think of it?" type discussions coming into the mix. I think it's just a matter of how you use it, if you choose to use it at all.

Sure, you're right.


message 207: by Stephen (new)

Stephen You know what would be cool? If the list of "Genres You’d Like to Hear About in Your New Releases Email" included a section entitled something like "Culinary/Cooking/Foodie/Gastronomic."


message 208: by Chris (new)

Chris I just looked at my recommendations and saw several new books to read in the first 30 seconds. Like many others here, my to-read list will be getting much longer. But seriously this is a great way to learn about new books and authors. Thanks!


message 209: by Diane (new)

Diane I was just thinking recently that it would be nice if you had a personal recommendations list like Netflix, and here it is! I already added a few to my "to read" shelf. This morning, though, every time I tried to rate a book on the list that I'd already read, I got an error saying "Problem saving!"

message 212: by Ana (new)

Ana I already added around 20 books which I didn't even know I would like..GR you rule!Thanks a lot!!!


message 213: by Charlene (new)

Charlene I am nervous about this. I put all of my hundreds of reviews on Living Social and (my mistake) didn't write them on a word doc or with evernote... When they shut down last month without giving me notice. I lost everything.

Is goodreads gonna be around?

I wouldn't worry about that - we plan to be around for a long time :)

If you want to have a backup file with all your reviews, you can export one here. The option is on the right side of the page.

message 215: by Jed (last edited Sep 19, 2011 03:52PM) (new)

Jed I'm excited, but I still wish books had ratings like movies. I really get tired of reading trashy books. More data points!


message 216: by Chip (new)

Chip Maxwell Super excited about this, and just went through and finally added each book to a few shelves.

But I do wish that my ratings were included, not just my tags (if they are, it doesn't seem like it).

Also, I'd rather have 5 dead-accurate recommendations than 2000 almost-considerable ones.

If you bring those two variables together in the algorithm, suddenly you get a recommendation that's more "because you really liked this, and really liked that, you'll probably love this."


message 217: by Colleen (new)

Colleen Clark I'm ambivalent. I have piles of unread books. Many of the recommended books are in my piles. Others I've decided not to read. But often the difference between what I already know about and even own and what I don't know about or has a lower priority is arbitrary. So it's less that I'm "not interested" but that I've other priorities. Like a lot of readers I have many interests and want to keep a lot of interest balls in the air. With childrens' books, for example, I added ones I particularly liked or remembered from reading to my children and grandchildren but I'm not trying to have a comprehensive list. But to say "not interested" isn't correct either.


message 218: by Amy (new)

Amy Very awesome! I have been using Goodreads as a way to keep track of what I read, so I haven't been reviewing titles that I have read before I joined (like 4 or 5 years ago). Occasionally, I get recommended books that I had already read. But from what I understand, if I mark them Not Interested, it effects my other recommendations...Is there a way to delete books from the rec list without effecting my choices?


message 219: by Amy (new)

Amy I have already added like 10 titles to get on my paperbackswap.com account! Going to have to work on getting rid of some books in order to have shelf room!


message 220: by Dee (new)

Dee you could hide that shelf and not get recommendations for it - then when you decide you do want rec's change the configuration

message 223: by Timothy (new)

Timothy Great , but it needs a little work. I have many books recommended, that are written in languages that I don't speak or read. Am I set up wrong or is a fix needed?


message 224: by Chara (new)

Chara I've been waiting for something like this to come out and I love it!

I think it works great--its really giving me ideas of books to read and helping me to remember books that I forgot all about!!


message 225: by John (new)

John Fab idea!

The only issue I've found with it so far, is that it's recommending titles that are already on my shelves, albeit different versions ( Neil Gaiman's Neverwhere, for instance ).

Can't wait for this to be implemented on the iOS app....


message 226: by Susan (new)

Susan Well... Because I liked The Hunger Games books, I got innundated with children's books, which were not appealing to me at all. Don't know how romance got sent to me as a recommendation, except I do like Jane Austen - but in general, I hate romance novels. My first foray into fantasy was GAme of Thrones, but I am tired halfway through Book 2, so most of those recommendations were not on point. When I tried to rate already read books, I got a message "problem saving." I did find about three or four books TBR, so it was a worthwhile excercise, but it took an awful lot of misses to get those three or four. I am not sure this is a great system - yet.


message 227: by Pippa (new)

Pippa Fantastic idea, I'll never be stuck for ideas again. I have one more request - can you increase the number of hours in a day so that I have more time to read all these new books!


message 228: by Nick (new)

Nick Knowlson That's amazing, thanks so much Goodreads team!


message 229: by Karen (new)

Karen I love this capability! Only trouble is that too many books are listed under each of my categories. Rather than fifty titles, I would like about 25. I get frustrated when there are too many choices. Hope the algorithm could look only at books I rate as 4 and 5. Wonderful addition to Goodreads. If only I could get more of my friends using it!

The more you indicate "not interested" on those children's titles, the less they will show up. The algorithm gets smarter based on your feedback. You might also try putting your younger titles on their own shelf and opting them out of recommendations (on the "edit bookshelves" page).

What browser are you using? Does this happen on multiple browsers?

Oops! Would you mind sending some examples to support [at] goodreads [dot] com so we can investigate?

Were they different editions of the same book? Which books were these? (this will help us to prevent this from happening in the future)


(Customer Care Manager, Goodreads).


message 233: by Alyce (new)

Alyce They may indeed have been different editions- one of the books was "The Strange case of Dr. Jeckle and Mr. Hyde" (RLS) and I see that there are several versions to select from on your list. In fact, all of the duplicates were classics. Thanks for addressing this.


message 234: by William (new)

William Whitener Well, when I tried to access the new system, I got a message "Goodreads is not available at this time. Please try again later."!!


message 235: by Kirsten (new)

Kirsten I checked my recommendations and they were WAY off course! I've rated over 100 books, so I'm not sure why this would be. The genres were Business, Fantasy, Children's, Young Adult, and Classics. I've never read a Business book in my life-- and never will! I despise Fantasy. Why are these genres even showing up for me? I agree with Jeannette, it seems to recommend books it thinks I would hate!

Audra Kirsten wrote: "I checked my recommendations and they were WAY off course! I've rated over 100 books, so I'm not sure why this would be. The genres were Business, Fantasy, Children's, Young Adult, and Classics. ..."

The genres are based on your favorite genres.

You can edit your "favorite genres" by hovering over the question mark next to "Recommendations by Genre" (on the right). Just click "favorite genres".

As soon as you do so, you will start receiving recs for the genres you picked.


message 238: by Michael (new)

Michael Too much fun. While i hadn't expected my ratings of books i read long ago to be added, i was impressed by the recommendations. I was so appreciative i wrote a first review. When i find an author i like, i like to read other books that come out or have been written by the same author, and discovering new authors or reading a different genre for a change is particularly wonderful.


message 239: by Steve (new)

Steve What an awesome help! I've investigated those on the list I hadn't read, found many appealing recommendations, and have already purchased five for my eReader. Several others made my wish list or are books I'm waiting to be available that way. Kudos and thanks.


message 240: by Inna (new)

Inna You have options "Want to read" and "Not interested". Could you add the option "Already read"? It will allow to offer something else to the recommended books instead of the books that you have already read.

For example, at present I am recommended to read about 10 books that I have already marked as read in my aacount.


message 241: by Alyce (new)

Alyce I agree that an "already read" option would be helpful; for both recommendations for titles already listed as read, as well as those read before joining GoodReads. Thanks.


message 242: by Julie (new)

Julie Malo-Sauvé This is a great idea! If I had one suggestion to give you, I would propose that your recommendation tool recognize the books' language that are rated.

This way, if I mostly read in French, the recommendations I get would be mostly French language authors. Thanks!


message 243: by Kirsten (new)

Kirsten Well, I changed my genres and the recommendations were much improved. Still, I don't see how it chose my so-called favorite genres in the first place. Some books may be in the wrong category. For example, because I rated "Go the F*** to Sleep," it decided I like Children's books, perhaps? That is NOT a children's book!!!


message 244: by Abe (new)

Abe Mercer I really love the recommendations feature, I now have WAY too many books to read.

I just found this site a couple of months ago, I want to thank all the people who work on Goodreads for improving my reading experience by connecting me with great books, reviews and people. Thank you!


message 245: by Kelvin (new)

Kelvin Rugg Using a secret sauce (a.k.a. proprietary algorithms) and 20 billion data points provided by the world's largest community of readers (that's you!), our recommendation engine analyzes both books and, more importantly, the people who read them.

A saucy secret! Goodness me Goodreads, whatever next.


message 246: by Pati (new)

Pati I love your whole concept but upon looking at the recommendations that ya'll had listed for me I immediately spotted a major oversight. The Recommendations need to recognize sub-genres. First and foremost I read Romance and yet the recommendations had romance being my lowest rated genre and my highest rated genres as Fantasy and horror, because it didn't recognize the very basic fact that all of the fantasy and paranormal books that I read are sub-catagories of romance.


message 247: by Catherine (new)

Catherine Blair This is incredible as it took what I love and showed me what I could love to read in the future. It's always a hit or miss with many books and this really, really hit the mark. I am looking forward to testing this with my next book purchase from your recommendations. This is very exciting for me.


message 248: by Ronmaes (new)

Ronmaes Finally! Recommendations meant exactly for me! It will lessen the time I spend looking for new books. Thanks goodreads!
