--- date: 2021-01-27, 2022-06-05 aliases: Hub notes --- # [[Structure Notes]] Structure notes, or structure zettel, are elements of a [[Zettelkasten]] [[Personal Knowledge Management|PKM]] system that introduce a topical hierarchy to organize zettels into. Structure notes are similar to the idea of a [[Map of Content]], although an MoC has a connotation of operating only on the top level. Structure notes can be used to simply group a bunch of related notes together, even if it's not a zoomed-out topic itself. Ideally, structure notes would be created after clusters of notes organically form around a topic. However, the biggest problem with structure notes is that it can be difficult to identify these clusters. Graph views from the likes of [[Obsidian]] and [[Roam Research]] (although Roam's is pretty basic) may help to highlight these clusters. Another effective technique may be a weekly or regular review of maps of content. ## Implementations - In [[Zettelkasten]], Luhmann used Hub notes - [[Nick Milo]] talks about using a [[Map of Content]].
