To use this book, simply open it up and start reading. You can hold it in your hands, place it on a table, or use a bookstand. When you're done reading, close it gently to avoid further damage to the detached spine. As for maintenance, keep it in a dry and cool place away from direct sunlight to prevent further staining and foxing. If the dust jacket gets dirty, you can use a soft, dry cloth to gently wipe it. Be careful when handling the book due to the detached spine and the splits in the dust jacket corners. Don't bend the pages or put too much pressure on the binding to keep the pages firmly bound.
