To use this book, simply sit back, relax, and start reading to explore the behind - the - scenes of Star Trek. When handling it, be gentle to avoid further wear on the cover and spine. Since the pages are discolored from age, try not to expose it to direct sunlight for long periods as it may cause more damage. Store it in a dry and cool place to maintain its condition. If you want to keep it clean, use a soft, dry cloth to gently wipe the cover. Don't write or mark in the book to preserve its value.
