This volume contains 17 mathematical works by Johann Bernoulli, written between 1680 – when he was only 13 years old and studied mathematics with his brother Jacob – and 1732, when he was 65 years old.

Five of the works are handwritten manuscripts, and another three belong to the Anekdota, which he published in the fourth volume of his Opera Omnia.

The book features also seven works by other authors: John Craig, Jacob Hermann, Gottfried Wilhelm Leibniz, and Ehrenfried Walther von Tschirnhaus. Another work included in this book was co-written by Johann Bernoulli and Samuel Klingenstjerna.
