Works in the Public Domain are freely available to use because they have fallen out of copyright, or were created without it. Books, audiobooks, videos, photos, articles, and more can be found—but keep in mind that most items in the Public Domain are 100+ years old.

Also important to keep in mind is that copyright laws vary from country to country. Something that might be in the Public Domain in another country won’t necessarily be in the Public Domain in the US, and vice versa.

The online resources below all house digital versions of Public Domain materials.
