This is a valuable old book. When using it, handle it gently because the pages are very thin. To avoid further wear on the gilded text block and the cover, don't put it in a place where it will be rubbed against other objects. When you're done reading, close it carefully to keep the binding tight. You can store it on a dry and clean bookshelf. Also, don't dog - ear the pages to keep the book in good shape. If possible, you can use a book cover to protect it from dust and scratches.
