# Zettelkasten #seed This note is still growing. --- A zettelkasten is German for "slip box", and has come to popularity based on the note-taking and personal knowledge management system used by German sociologist Niklas Luhmann. This influences my [[Digital garden]] approach by treating this as a collection of standalone ideas, references, insights, and quotes… though I have been leaning more towards [[Evergreen notes]] over the more rigid Zettelkasten method itself. I read about the concept in [[ahrens2017HowTakeSmart|How to Take Smart Notes by Sönke Ahrens]] after hearing about it on the podcast, [Cortex](https://www.relay.fm/cortex/105), and then promptly ignored it for the better part of a year. With the Zettelkasten method, there are three different types of notes: fleeting, permanent, and project. Within permanent notes, there are two sub-types: literature notes (reference) and slip-box notes. Where [[Evergreen notes|evergreen]] and zettelkasten differ, however, is that once a permanent note is written, the note is never amended, only added to with a linked card. For anyone familiar with the productivity system, [[allen2015GettingThingsDone|Getting Things Done (GTD) by David Allen]], there’s a nice commonality between the two methodologies. Broadly speaking, both prioritize externalizing your thoughts: with GTD, you externalize your tasks to help clear up your mind for better productivity and focus. With Zettelkasten, you externalize your thoughts to help make new and interesting connections between them. > [!cite]- Reference > ```dataview > TABLE WITHOUT ID > link(file.path, title) AS "Title", > type AS "Type", > keywords AS "Keywords" > FROM "50 Reference" > WHERE contains(keywords, this.file.link) > SORT type, title asc > ```
