A single folio that has lost its mate (the other half of the bifolium) or that originally was designed to be sewn into a book as a single sheet. The latter situation could occur when the layout of the book did not require a text or image to follow immediately at that point, or when that folio carried work, such as a miniature, which was executed by a separate member of the work team.
