If you own this vintage book, here's how to handle it. When reading, hold it gently by the edges of the pages to avoid damage. Don't bend the cover too much as it already has some minor wear. Store it in a cool, dry place away from direct sunlight to prevent further discoloration. If there's dust on it, use a soft, dry cloth to gently wipe the cover and pages. Be careful not to touch the pencil text on the front free - endpaper to keep it intact. Since the bindings are tight, don't force the book open too wide to maintain its sturdiness.
