Fun fact: Octavo, a Latin word meaning "in eighth" or "for the eighth time", is a technical term describing the format of a book, which refers to the size of leaves produced from folding a full sheet of paper on which multiple pages of text were printed to form the individual sections (or gatherings) of a book. - Wikipedia
