How to use: You can start by browsing through the colorful illustrations to get an overview of the various animals and plants. Then, you can read the text for detailed information. If you're interested in a specific topic, use the index at the back. Note that the book has some wear and tear, so handle it gently to avoid further damage. Maintenance: Keep it in a dry place away from direct sunlight to prevent the pages from yellowing and the cover from fading. You can also use a bookend to keep the binding in good shape.
