Another take on the recommendation engine website (like Pandora does for music).

You can just go to whatshouldyoureadnext.com and put in a book you like and the site will check their database of other readers' favorite books and suggest what you could read next. They compare it to "browsing the bookshelves of a very well read friend."

For the service to be more accurate, you should register (just an email address) and build your own list of favorite books.

I registered and entered a dozen, then asked for recommendations. I'd say that the results were pretty accurate to my taste because more than half of the recommendations were other books that I have read and enjoyed. (You can check THOSE titles off then and have them added to your list.) As your list grows, the recommendations get better - or more interesting.

So far, it really thinks I should read Fight Club.

They also have "What have I read tests" they compiled lists of users' most popular books (according to the number of lists they appear in) by genre (Top 25 science fiction/fantasy, classic fiction, modern classics, non-fiction etc.). Try those and it will build you list of favorites up and it's faster than typing in titles and authors. To save time on that process: if you want to add John Irving's The World According to Garp (and I would definitely have to add that one) you can just type Irving and World Garp and it will find it. The search is pretty good.

It's a cool service and it made me think about my favorite books again. So what's their business model? Books come with handy links to buying from Amazon (US or UK - it's a UK site), so if you click and buy, they make a little bit of money.

Take the'What have I read?' test in 8 different categories, and if there's something you like, buy your books at Amazon US or Amazon UK
