These books are great for language enthusiasts and researchers. To use them, simply open the pages and start reading. When handling, be gentle due to the fragile pages of 'The American Language'. To keep them in good shape, store them in a dry and cool place away from direct sunlight. Avoid getting the pages wet as it could cause further damage. If you want to flip through the pages, wash your hands first to prevent additional soiling. When not in use, you can place them on a bookshelf, but try not to stack heavy items on top as the bindings are already loose.
