Bring a document into Paper
Add a PDF or e-book to your library and keep the original file in view.
Paper works best when your library reflects the documents you actually return to. Start with a PDF or EPUB you already have on your Windows PC.
Add a file
Use the add action in the library, then choose the document from your files. Paper will place it beside your other reading material so it is easy to open again.
Keep the source clear
Your library is an organized view of your reading. Keep the original file where you can find it, especially while you are learning how you want to organize your collection.
A small library is a good library
You do not need to import everything at once. Add the books, papers, and long reads that you are actively using, then let your shelf grow naturally.
