If book boards (covers) are loose or detached, or an item has loose pages, it may be treated with cloth ties. Unbleached cotton tying tape holds all pieces of an item together and provides stabilization. The cloth is dye-free to prevent any bleeding of tape to item.
Sometimes items are tied together until they are ready to be repaired. In some cases, items will be placed on the shelf with ties because it is the most appropriate solution (e.g., it's the most economical, the item is low-use).
Once a volume is tied, we place an information sheet under the ties on the front cover; it instructs the user how to handle the item.
