Protective cover and dust jacket for book - is made of paper and transparent plastics sheet

摘要

The cover which protects a book and its dust jacket is made from a sheet of paper and a sheet of plastics. The width of the paper is equal to the height of the book and has a margin of 2 cm at each end when folded around the book. A sheet of transparent plastics as wide as the paper but 4 cm shorter is placed on the plastic sheet and the margins folded over. This cover is then slid over the dust jacket and the covers of the book to form a transparent outer cover.
