CORE DEFINITION
The leishu, or classified encyclopedia, is a long-standing Chinese genre of reference compilation, exemplified by works such as the Taiping Yulan and the Gujin Tushu Jicheng. Its core proposition is that scattered texts lose their value across generations, so knowledge should be gathered by category into a structured whole that can be retrieved rather than rediscovered. The key qualification is that compilation is not creation: a reference work preserves and organizes existing material, so it inherits the errors of its sources and requires attribution to remain trustworthy.
SCAFFOLDING EFFECT
Reduce cognitive load
- Use scope definition: decide which domains the compilation will cover and which it will not. - Use classification scheme: build categories that let a reader arrive from more than one direction. - Use source citation: record where each item came from so later readers can verify it.
Anchor fast decisions
Knowledge held only in scattered documents decays because retrieval depends on remembering which source contains what, and that memory dies with each generation. Classifying material by topic concentrates related items in one place, so the cost of finding becomes a lookup rather than a search. A stable category scheme also lets later compilers extend the work without reorganizing it, which is what allows accumulation across centuries. The gain is not new knowledge but reduced access cost, and that is what makes the compilation a durable asset.
