A paper-first reading field guide
Mark the Example That Changes a Definition
Use three linked fields: meaning before, boundary example, and meaning after. Keep each field brief and attach the page or chapter landmark that supports it.
Notice when an example stretches or overturns the working meaning of a term. A compact three-anchor trail keeps the note useful when you return later or discuss it with someone using another edition.
Step 1
Anchor the location
Record the page or chapter before interpreting the moment. Add the current reading boundary when later knowledge could change the note.
Step 2
Meaning before
Write the definition you were using.
Step 3
Boundary example
Anchor the example that no longer fits cleanly.
Step 4
Meaning after
Revise the definition only as far as the example requires.
