leaf tab markers

Small, usually rectangular, pieces of leather, parchment, paper or textile, often coloured or decorated, or even metal, which are adhered or occasionally sewn to the fore-edges of the leaves of a bookblock in order to mark permanently the locations of specific passages in a text, beginnings of sections, etc. They can be attached on one side of a leaf or, if folded, to both sides of a leaf. Some folded leaf tab markers were folded tightly over the edges of the leaves, others project from the edge to a greater or lesser extent. The outer ends of some folded leaf tab markers were formed into turk's head knots. They can have thread markers sewn through them. Sometimes the thread markers are attached to the leaf and the tab by a separate thinner thread sewn through the leaf and the tab. The inner ends only of leaf tab markers are sometime found preserved in books that have had their fore-edges cut as the result of trimming often during rebinding. They may or may not be be numbered or lettered, and could be added at any time after a book was bound.
