Benjamin Wardhaugh starts this section with an examination of the use of marks and more deliberate marginalia in 366 copies of eighteenth-century mathematical books; he finds approximately 85% of books bore varying evidence of use, which is likely an I under i count, particularly with respect to heavily annotated books, which are less likely to have been preserved than cleaner books. Together, these chapters expand our understanding of how university students and scholars - particularly those who would not go on to become professional mathematicians - encountered mathematics and engaged with mathematical books during the early modern period. Overall, this book is a thought-provoking collection of case studies that fulfills its subtitle's promise to explore the production, collection, and - most of all - use of early modern mathematical books.
