Printing: Renaissance and Reformation
This site from the University of South Carolina features images and descriptions of early texts -- some of which are over 400 years old. You can view the texts, which cover topics such as medicine, religion, science, and exploration, to see what early books were like and to learn more about the Renaissance and Reformation periods in Europe.
