This 2 - volume set is a great read for history enthusiasts. To use it, simply open the book and start reading. When handling, make sure your hands are clean to avoid adding more soiling to the covers and pages. Since the binding is loose and stiff, be gentle when opening and closing the books to prevent further damage. Store the books in a dry and cool place to slow down the yellowing of the pages. If you notice any loose pages, you can use some acid - free tape to reattach them carefully.
