a book made by folding large sheets of paper in halves
A folio is a type of book or manuscript made from sheets of paper that have been folded in half, creating two leaves per sheet. This method results in each sheet producing four pages of the book. Folios are typically used for larger volumes and are noted for their substantial and often formal appearance, making them suitable for important or high-quality publications.
