The book examines the lives and libraries of notable English book collectors, shedding light on their contributions to preservation and scholarship.

Fletcher emphasizes the importance of these collectors in rescuing valuable manuscripts and printed works from loss or destruction, particularly during the Reformation period. He notes that the current bibliophiles owe a debt of gratitude to these early collectors for their efforts and establishes a foundational understanding of the tradition of book collecting that the subsequent chapters will explore in detail.
