Trying to find good books to read during your commute or planning out your summer reading early? There is nothing more daunting than going to a bookstore without a shopping list. So, make sure that your next read is going to be a good one.

There are plenty of sites you can use to look up books based on your personal taste, favorite authors and titles, or even based on a specific plot summary or character.

Whether user-generated, based on recommendations, or using a book recommendation search engine, there are a variety of ways that these sites are going to answer the question: what should I read next?

1. Gnooks

Gnooks is probably the simplest of these sites to use. You can enter up to three author's names, and Gnooks will recommend another author you might like.

The interface is clean and distraction-free, but if you want to find out more about the recommended authors, you'll have to take your search elsewhere.

The only other feature on Gnooks is the option to make one of three selections: I like it, I don't like it, and I don't know. Making these selections probably helps Gnooks algorithm improve.

2. Goodreads

You should already be familiar with this book community. Goodreads is packed with features that go beyond book recommendations. You will have to sign up for an account to use the site's book recommendations.

There are several ways to discover books using Goodreads. You can search for a title, and you'll see a list of other titles users also enjoyed. If you sign up for a free Goodreads account and rate books that you've read, the site can also offer up recommendations based on your reading history.

In addition to these features, given that Goodreads is a social network, you can also scan the reading lists of other users and friends to find book recommendations.

Some users have also created themed lists which you can use to discover your next read. You can either search for titles you enjoyed and see which lists they appear on, and find other titles you might like.

For example, searching for The Alexandria Quartet is featured on a variety of lists such as best post World War II fiction, alongside other greats such as Catch 22. But then it also does wind up on a list of best books ever, alongside Twilight.

Goodreads isn't the only site that you can use to catalog your book collection and also benefit from the community's wisdom on what to read next. LibraryThing is another good example.

What Should I Read Next? (WSIRN) is a book recommendation search engine. It asks you to enter your favorite book and suggests similar books that you might find interesting. It also lets you browse books by subject.

WSIRN asks users to create reading lists of their favorite books. Thanks to these reading lists and its algorithm, it can understand which books are related to each other.

You can also add books to three default lists: books you liked, books you disliked, books you want to read. This will not only help the algorithm to improve, but you'll get better recommendations. Besides these three lists, you can create custom ones and make your lists private. WSIRN has a Quotes section as well, where you can discover new writers and read relevant quotations.

4. Litsy

Unlike most other sites listed here, Litsy doesn't rely on an algorithm. Instead, it relies entirely on its user base for this information. Though you can search for books without signing up, creating a Litsy account gives you access to more features. You can search for books, read reviews, add friends, create posts, and of course find your next read.

Once you've signed up, you'll get a list of users it recommends following. You can also search for other users to follow by searching for your favorite books and seeing who else has left reviews for them. When you want to recommend books for other users, you can't just give the book a thumbs up; you have to leave a short review.

And that's how you're going to find your recommendations—by seeing what other Litsy users are reading. Users post photos of the book (or screenshots of the ebook), along with their reviews.

To find a good book to read, you'll probably want to go directly to the profile of someone who has read other books you've enjoyed and also given them a ringing endorsement. Moreover, Litsy has a mobile application for recommending books.

5. AllReaders.com

AllReaders.com is another no-frills website without much of a UI to speak of, but it's a great option for those of you who are fans of thrillers. With AllReader.com's advanced search function, you can search for books based on plot, setting or even details about the protagonists. Titles are also accompanied by a plot summary, as well as setting and character information.

Plots or themes include a variety of thrillers, horror, and adventure—so this feature won't be wildly useful if you're looking for something a little more literary.

You can also select the era in which the story is set, the characteristics of the protagonist and the antagonist, the setting, and the book's writing style. Besides the advanced search, it has an option for searching books by title or author.

6. Amazon

Amazon should be an obvious option for searching book recommendations. You can find similar titles for any book since the search result is accompanied by a Customers who bought this item also bought list.

While Amazon uses this feature primarily to get you to buy more stuff, you can also take a look at the recommendations for items that are frequently bought together:

And, don't forget that Amazon is also home to the Kindle and its massive reading community too.

7. TasteDive

TasteDive (formerly TasteKid) is a great site for both book and author recommendations, along with other forms of entertainment. Just enter the title of your favorite book or your favorite author, and TasteDive will generate its recommendations.

TasteDive isn't only about book recommendations. You can also use it for music, movies and TV shows. By the same token, you can find recommended books based on other books, as well as based on authors, TV shows, movies, music, and more.

While TasteDive's recommendations are often pretty accurate, searching for recommendations based on newer titles or more obscure authors won't yield any results.

8. Whichbook

whichbook website

Whichbook is another site that offers up suggestions based on specific characteristics rather than similar books - you can make your choices based on the mood of the book, using a series of sliders: Happy to Sad, Funny to Serious, Safe to Disturbing, and so forth.

Drag up to four sliders around to make your selection for each characteristic of the book, and Whichbook will offer up a long list of recommendations. You can also opt for making your selection based on specifics regarding character, plot, and setting. Additionally, you can find books by country and browse through bestsellers.

9. BookBub

BookBub is worth a look for its handpicked recommendations. You can also save yourself some money with discounts on books they think you'll want to read.

When you first sign up, BookBub will ask you some questions on what kinds of recommendations you want (updates from authors you love, recommendations from people you trust, info on discounts etc.), and of course information on the genres of books you like.

You can also follow your favorite authors, and in some cases (like Margaret Atwood for example), you'll get recommendations straight from them. In addition to recommendations for people you follow and auto-generated lists, the editors' picks is a great way to discover new titles in your favorite genres.

10. Olmenta

Use Olmenta for random finds if you love to be surprised. The site is simple: you can select books based on nine genres including poetry, children's books, and business.

There are no signups, no algorithms, and no real explanation as to how the books end up on the list, except for a link to recommend books via Twitter to the brains behind the operation.

11. Reddit

The Subreddits /r/Books and /r/BookSuggestions are a good place to go to find other like-minded people on the hunt for a good read. You can search the previous threads, or create a post yourself asking for suggestions if you're looking for something in particular.

/r/Books also has a book recommendations tab, where you'll find a weekly recommendation thread. Here, you can request suggestions and can help out other readers with suggestions of your own.

Add Books to Your Reading List

If you're having a hard time finding books to read, it's worth giving these websites a shot. Some share recommendations based on user reviews, while others use algorithms and databases to find the book you'll love.

Once you visit a few of these sites, you can easily find several books to include in your reading list. After adding all the book suggestions to your reading list, you can visit Amazon or other online stores to get your copy.
