Your library
Keep PDFs, books, and the documents you return to in one calm place.
The library is Paper’s front door. It gathers the documents you are reading and gives them enough structure to be found again without making you manage a database.
Build a shelf that helps
Start with the documents you use. Add books, papers, and long reads as they become part of your current season of work or study.
Return by recognition
Cover, title, and a familiar place on the shelf can be more useful than a deep folder tree. Keep the system light enough that you will actually keep using it.
