The reproduction of each page is preceded by a label divided into two parts: one indicating the sequence number under which the front or back of a folio is published, the other being reserved for the classification of subjects unrelated to Nerves and Vessels.
This organizational system was created by the 1901 editor, Édouard Rouveyre, to help scholars navigate Leonardo's often disorganized notebooks.
