Quick Summary

The Macropædia was a part of the 15th edition of the Encyclopædia Britannica, known as Britannica 3. This edition, published in 1974, was a significant undertaking, involving over 4,000 contributors from more than 100 countries. The Macropædia was designed to provide "Knowledge in Depth," offering longer, more comprehensive articles on broad topics. It was structured to reflect the interconnectedness of knowledge, complementing the shorter entries in the Micropædia (Ready Reference and Index) and the topical guide of the Propædia (Outline of Knowledge). The Macropædia was restructured in 1985, with hundreds of articles amalgamated and regrouped. Printings of the 15th edition continued into the 21st century, with a focus shifting to digital versions.12
