These books are great for religious study or collection. To use them, simply open the covers and start reading. When handling, make sure your hands are clean to avoid soiling the pages. Since they're older books, it's best to be gentle when turning the pages to prevent tearing. To keep them in good shape, store them in a dry, cool place away from direct sunlight. You can also use a bookend to support them on the shelf and keep the bindings tight.
