# Barter

## Definition
Barter is a method of exchange by which goods or services are directly exchanged for other goods or services without using a medium of exchange, such as money. It is a form of trade that predates the use of money.

## Source Chapter
Book 1, Chapter 4

## Context
Smith explains the limitations of the barter system, especially in a society where the division of labour is prominent. These limitations, according to Smith, led to the development and use of money as a common medium of exchange.

## Economic Domain
Economic Anthropology, Economic History, Microeconomics
feat(infospace): flat canonical entity set with cross-chapter deduplication Restructure entity storage from per-chapter subdirectories to a flat canonical set in output/entities/. Each entity exists as a single file; duplicates across chapters are detected by slug collision and skipped (first occurrence wins). Chapter views use {{ include }} transclusion to reference shared entity files. Add @{existing_entities} macro to extract-entities template so the LLM knows which entities already exist and focuses on genuinely new ones. Refactor _call_llm() from _execute_llm() for callers that handle their own file I/O. 41 unique entities from 4 chapters (2 duplicates removed).
