If you're using this book, simply open it up and start reading through the content. When handling it, be gentle because the binding is loose, so try not to bend it too much. To keep it in its current condition, store it in a dry place away from direct sunlight as the pages and covers have some discoloration already. Avoid getting the book wet as that could make the yellowing and discoloration worse. When you're done reading, close it carefully to prevent the binding from slipping further.
