Basically, 2019 marks the first time a huge quantity of books published in 1923—including works by Virginia Woolf, Agatha Christie, and Robert Frost—have become legally downloadable since digital books became a thing. It’s a big deal—the Internet Archive had a party in San Francisco to celebrate. Next year, works from 1924 will enter the public domain, and so-on.

So, how do you actually download these books?

It largely depends on what site you go to, and if you can’t find a book on one site, you can probably find it on another. For instance, ReadPrint.com, as well as The Literature Network (mostly major authors), and Librivox (audio books), Authorama (all in the public domain), and over a dozen other sites all have vast selections of free ebooks.

There’s actually quite a few very interesting books that have just entered public domain status.
