Free books and guides. Upload a file or link to one that already lives online.
Only publish what you have the right to share.
Use public-domain works or books whose author/publisher offers them free. When in doubt, link to the official free source rather than uploading a copy.
Add a resource
Leave the file empty and use the link below to point at an external free source instead.
If both a file and a link are set, the app opens the uploaded file.
