Enlightenment ideals of reason informed the foundation of the Revolution

From the 17th to 19th centuries, an intellectual movement took place in Europe and its colonies that emphasized reason over authority.

Circulating libraries helped the novel's popularity surge

As literacy rates began to rise in the 19th century, so did the demand for reading materials. The only problem? Newspapers and books weren’t cheap, and newly literate middle-class families struggled to afford literature.

This was eventually called a circulating library, an innovation that would satisfy the burgeoning readership of novels and increase literacy rates further.
