# Why Paper Identity Belongs in Every Study Note

A study note should still make sense after it has been copied, shared, or found months later. Put the subject, year, jurisdiction, paper name, question number, and source near the top. These fields let another reader recover the same material without guessing.

The Gaokao subject directory organizes current material by named paper and states the available scope. Follow the same pattern in screenshots and error logs. An identified example can be useful without being mistaken for a universal Gaokao format.
