INTRODUCTION

English translation pending.

CORE DEFINITION

The Siku Quanshu classification is the four-part scheme used by the imperial library of the Qing dynasty to organize the whole of the received literature, dividing all books into the classics, the histories, the masters, and the collections, with ten categories under the classics, fifteen under the histories, fourteen under the masters, and five under the collections, forty-four categories in total, across more than three thousand four hundred works. Its core proposition is that a vast body of writing becomes usable only when a stable top layer of four bins is fixed, and that the order of the bins is itself a statement of value. The key qualification is that the scheme orders a premodern world of knowledge and must be translated before it can carry modern disciplines.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use four-bin sort: put any incoming material into classics, records, masters, or collected works first. - Use subdivide: break each bin into its named categories before the collection grows. - Use order reading: notice what the order of the bins says about what the system values most.

Anchor fast decisions

A library without a fixed top layer is sorted by the last person who shelved it, and the bigger it grows the more the order drifts, until nothing can be found by rule. Four bins at the top fix the first decision for every item, which is what makes an index possible at scale. The order of the bins also carries the hierarchy of the culture that set them, so the scheme sorts knowledge and states a value system in the same move.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Fix the four top-level bins for the collection before adding anything to it. 2. Assign every existing item to exactly one bin, and note the hard cases. 3. Break each bin into its named subcategories as the need appears. 4. Review the order of the bins and say plainly what it ranks first.
