To use this book, simply open it and start reading. It's a great resource for exploring the concepts of kinship and marriage. When handling the book, be gentle to avoid further damage to the slightly bowed pages and the dust - jacket with corner tears. Store it in a dry and cool place to prevent staining and sunning from getting worse. If you want to keep it in good condition, don't place heavy objects on it. And try to keep it away from liquids to avoid any more stains on the text block.
