This book analyses political reading and the subscription library to examine the social, political and intellectual fabric of Georgian Britain between the French Revolution in 1789 and the passage of the first Reform Act in 1832. Combining methodological elements from political and reading history, this book uses extensive borrowing and administrative records, bibliometric data, correspondence, diaries, and electoral and associational records from archives across the Anglophone Atlantic. Two libraries, the Bristol Library Society and the Leighton Library, Dunblane, and their communities are examined in detail to demonstrate the political importance of an institution which was ubiquitous within Georgian society.
