Is there a website that recommends books based on what other books you like (or dislike)?

http://www.tastekid.com/ does music and books.

And http://www.literature-map.com/ is from the same people that do music-map.

Amazon.com
Audible.com

Goodreads.com

@johnpowell I lurve you.

goodreads :)

Have these actually worked for you? (I know there are sites for this. I should have specified ones that have worked for you.) I’m thinking algorithms for literary preference might be tricksy.

@Nimis hmm to be honest I don’t use it to its full potential, just to keep a list of books I’ve read. Macbean uses it a lot though, I’ll send this question along for you.

Thanks, shrub.
Nice to see you too. :)

This previous fluther question has some additional answers that are not mentioned above (I am too lazy to cut and paste each one of them).

@Kayak8 :: Great answer for admitting to being lazy. That is how I roll too.

@Kayak8 I’m all for laziness and diggin’ up old questions. Tried to do a search before I asked this, but didn’t find that one. Thanks!

librarything.com—also allows you to card-catalogue your own library and find out how many people in membership have same book [giving some idea of rarity]. Good site!

Goodreads.com I belong to this one myself.
