Literature Notes Test Understanding; Permanent Notes Carry Your Own Thought
The slip-box method draws a hard line between two distinct kinds of notes — and collapsing them is one of the most common ways the system breaks down. Reading.md
Literature Notes: the comprehension test
A literature note is a source's ideas restated entirely in your own words. Its job is diagnostic: if you cannot restate the idea faithfully without looking back at the original, you did not understand it yet. The act of writing the note *is* the test.
"Separate literature notes (a source in your own words) from permanent notes (your own thought). The first tests understanding; the second stays in the slip-box." Reading.md
This connects directly to writing as a tool for thinking: restating someone else's idea in your own language forces genuine processing, not passive reading. It is the written equivalent of the Feynman technique — explain it simply, or admit you don't know it.
Literature notes are temporary scaffolding. They belong to a source file or inbox, not to the main slip-box body. See Ahrens — How to Take Smart Notes for an example of this note type in practice.
Permanent Notes: your own thought in the slip-box
A permanent note is written in your own voice and captures *your* insight — a claim you are willing to stand behind, not a summary of someone else's. It is atomic (one idea per note) and is written to be re-readable years later without the original context.
The permanent note is the only kind that lives in the slip-box proper, where it can accumulate links and participate in compounding knowledge.
Why the distinction matters
| Note type | Voice | Purpose | Lives in |
|---|---|---|---|
| Literature note | Author's ideas, your words | Test comprehension | Inbox / source reference |
| Permanent note | Your own thought | Build lasting insight | Slip-box proper |
Mixing the two is dangerous: you end up with a slip-box full of other people's ideas, never your own. The literature note is a means; the permanent note is the end.
Because permanent notes must be written in your own voice, forging one well is not a shallow task — it requires genuine focus. That is also why a single reading session can produce several literature notes but only one or two good permanent notes.
How the two note types connect in practice
- 1.Read and capture a literature note → example from Ahrens
- 2.Ask: *what do I actually think about this?* → draft a permanent note as a full claim
- 3.Link the permanent note outward to related ideas already in the slip-box
- 4.When a cluster of permanent notes builds up, consider a Map of Content to navigate the theme
Navigate all permanent notes from the slip-box home.
