This is a set of a service manual and a wiring diagram manual used by Ford technicians.  You will receive 2 manuals in the set:  The service manual and the wiring diagram book.  It has way more detail and information than a Chilton's or Haynes manual.  It is used, but in good condition.  All the pages are present and they are easily readable (see a representative page in the photos).  This was written by the Ford Technical Publication Department.  The manual is 4 pounds and almost 2 inches thick!!  See photos for additional details.
