Using this book is as simple as opening it up and starting to read the amazing story by JD Salinger. When handling the book, be gentle because it's a vintage item and has some signs of age. To maintain it, store it in a dry and cool place, away from direct sunlight to prevent further discoloration. Avoid getting the book wet as it could damage the pages. Also, try not to bend the spine too much to keep it in its current condition for a long time.
