Book Description
"The last great work of the age of reason, the final instance when all human knowledge could be presented with a single point of view ... Unabashed optimism, and unabashed racism, pervades many entries in the 11th, and provide its defining characteristics ... Despite its occasional ugliness, the reputation of the 11th persists today because of the staggering depth of knowledge contained with its volumes. It is especially strong in its biographical entries. These delve deeply into the history of men and women prominent in their eras who have since been largely forgotten - except by the historians, scholars"-- The Guardian, https://www.theguardian.com/books/booksblog/2012/apr/10/encyclopedia-britannica-11th-edition.
