# + About Higher Order Notes #note/readme📄 These notes are what give angles of structure to the inherent boundless and unstructured nature of Zettelkasten notes, specifically, Permanent and Literature notes. This happens in two specific fashions: * **MOCs** - [[Map of Content (MOC)]] aim to provide a perceived "vertical" structure or grouping to an otherwise flat file hierarchy of notes in these folders. * To see a roll-up of the MOCs, see [[Garden Home#Maps of Content (MOCs)]]. * *Note, because Obsidian Publish doesn't leverage data views, the only MOCs tied to the Garden note are hand-entered* * **Indexes** - These views index relevant notes in a table or list format in more of a horizontal manner. This enables you to see all of the notes that're relevant to a basic concept, tag, etc. [[Index - Books]] is an excellent example.
