“Zettelkasten is German for "slip box"(Plural: Zettelkästen). In analog form, a zettel is literally a box filled with slips of paper witha note on it, as well as metadata used to organise those notes. The Zettelkasten method is a way of organising paper in a non hierarchal way. Instead of being restrictedb to keeping a note in only one place,or having to make multiple copies of the same note to put in various places,notes are organised so that you can arrive at one individual note through multiple routes, and that note can lead you to various other notes-much like today's internet, but in paper form.” LearningNote TakingZettelkasten Book:Digital Zettelkasten: Principles, Methods, & Examples Source: Digital Zettelkasten: Principles, Methods, & Examples
