Copyright protection for most novels of the Roaring Twenties has expired. As a consequence, all of the 1920 bestsellers are available in digital format. Links in the list below are to the Gutenberg Project unless otherwise marked.
If you prefer print to pixels, you’ll find some of the books still around: paper those days was good quality.
