This was a new paperback book with the individual sections glued to a card spine. It was bought as a reference book and the owner asked if something longer lasting was possible.     Because the sections were sewn, (ie each folio had a fold down the middle), I was able to rebind the book creating a hard cover.   I cut the illustrations from the original paper cover and incorporated them into the binding. A new case was made using navy blue buckram.   I also treated the page edges with graphite giving a shiny metallic appearance.  The book now opens well and will be hard-wearing.
