Abstract
A protective book cover of transparent plastic is formed with a strengthened spine section provided by a combination of a spine reinforcing strip and decreased height of the spine section of the protective cover. The book cover receiving pockets of the protective cover are formed with inwardly convex slant-cut edges to facilitate insertion of the book covers, and a card pocket is formed in one of the pockets by a slant-cut slit that is convex upwardly to provide an easily accessible opening. A heat weld seam forming the front and back cover pockets is provided with sharp rectangular inside corners for a closer fit of the protective cover to the book. The protective cover is adjustable for book width by forming it of a primary or outside panel that is scored for separation of a back cover portion which may be adjustably positioned and adhesively secured to a front cover portion.
