"Slip box" note taking scheme. Zettelkasten notes are characterized by small note-cards that feature: - A unique identifier - The body of the note - Source or reference information for the source of knowledge - This can be omitted if the source is original thought The [[Wikipedia]] article doesn't cover much, but there are plenty of sites around that go over the method: - [A Beginner’s Guide to the Zettelkasten Method](https://zenkit.com/en/blog/a-beginners-guide-to-the-zettelkasten-method/) - [Introduction to the Zettelkasten Method](https://zettelkasten.de/introduction/) ## Zettelkasten's use in the Athenaeum As called out in the [[Athenaeum]] description, the Zettelkasten structure is utilized for notes that don't fit into one of the several hierarchical structures represented as folder hierarchies. As such, it is the default location for new *permanent* notes. Transitory notes go in `Inbox/` where they periodically get archived or rewritten as permanent notes.
