Book history is the study of the development and evolution of books from ancient times to the present. It examines how books have been produced, distributed, and consumed, focusing on various formats such as scrolls, manuscripts, and printed texts. This field also explores the impact of technology, like the invention of the printing press by Johannes Gutenberg in the 15th century, which revolutionized the way information was shared. Additionally, book history looks at the cultural and social contexts surrounding books, including their role in education, religion, and politics. It considers how libraries, publishing, and literacy have shaped societies and influenced the spread of ideas throughout history.
