The taxonomy
13 categories
Each group prints the rule for what files there, so a reader can predict where a term will land before opening it, and each holds the terms filed elsewhere that belong here too.
- Abstract & ExistentialFailure, the future, change, infinity, being forgotten.
- Animals & CreaturesThe largest group in the catalogue and the oldest.
- Blood, Injury & MedicalThe one group whose physiology runs the other way.
- Food, Eating & SwallowingVomiting, choking, swallowing and specific foods. [[fear-of-vomiting|Emetophobia]] is the entry that carries the group: it affects roughly nine per cent of people, it is **one of the most treatment-sought specific phobias**, and its own literature describes it as an elusive predicament because so little research has been done on it.
- Nature & Natural EnvironmentHeights, deep water, storms, darkness and fire.
- Numbers, Words & SymbolsThe number thirteen, the number four, 666, long words, palindromes and mathematics.
- Objects, Figures & PatternsClowns, dolls, masks, holes, mirrors and buttons.
