16 Best Sites to Download Free Books in 2021

Love to read? Then you'll love these places to find free books

Ever thought of creating a library with thousands of free books? You'd never have to spend a dime. It sounds impossible, but it's not. Free books on nearly any subject you can think of are all over the internet, ready to be downloaded, read, and shared. These are the 16 best sites with free books covering a wide variety of subjects, anything from romance novels to computer technology manuals.

A huge quantity of books previously unavailable to the public was released starting in 2019 thanks to the Sonny Bono Copyright Term Extension Act of 1998. Because of an amendment to that act, works published between 1923 and 1977 can enter the public domain 95 years after their creation. Many of the sites listed below give access to the tens of thousands of books (plus movies, songs, and cartoons) available under this act. Downloads should be free and without retribution under U.S. copyright law.

ManyBooks is one of the best resources on the web for free books in a variety of download formats. There are hundreds of titles here in all sorts of interesting genres and they're completely free.

Unlike some sites, this one lets you browse free books by language. You can also search by author and genre. The ManyBooks Articles page is another handy way to browse their collection, with articles such as "Books Like Hatchet" and book reviews.

Downloading books requires a free account login. Then, you're then given several download options, such as EPUB, MOBI, PDF, FB2, RTF, HTML, and more. They're also readable online through the site's built-in book reader.

One easy way to stay updated with new ManyBooks titles is through their RSS feed.
