labels (identifying artifacts)

Pieces of paper, leather, fabric, or small tablets inscribed and affixed to something for identification or description. In the context of bookbinding, refers specifically to paper or other material separate from that used to cover a book, on which the author's name and the title are printed or engraved and glued to the spine or front board. For larger, more public identifying notices, use "identification signs."
