 Modern bookmarks are available in a huge variety of materials in a multitude of designs and styles.Many are made of cardboard or heavy paper, but they are also constructed of paper, ribbon, fabric, felt, steel, wire, tin, beads, wood, plastic, vinyl, silver, gold, and other precious metals, some decorated with gemstones.The first detached, and therefore collectible, bookmarkers began to appear in the 1850s.
