“Zettelkasten” literally means “slip box,” i.e., a box holding index-card notes.

So what kind of notes can we have in our Slip Box?

- **Fleeting notes** – quick, disposable captures of ideas or observations; process or delete soon after.
- **Literature notes** – brief, cited summaries of what a source says, written in your own words.
- **Permanent notes** – distilled, stand-alone insights that connect to other notes and stay in the system.
- **Structure / index notes** – hub pages that group and link related permanent notes to show the big picture.
- **Project notes** – ad-hoc planning, to-dos, or drafts tied to a specific project; archived when finished.
