2018 Directory Iron and Steel Plants AIST paperback reference book

2018 Directory Iron and Steel Plants AIST paperback reference book Thick paperback. Pages look crisp and clean, I don’t detect any writing other than “property of” . Minor wear on the outside cover. Possibly includes some sort of disc in the back, still in plastic wrap, I haven’t seen this type of disc before so I’m not sure exactly what it is called.
