These two history books are great for anyone interested in learning about the past. To use them, simply open the pages and start reading. You can take notes in a separate notebook if you want to keep track of important points. When handling the books, be gentle, especially with 'American History' as its covers are a bit loose. Avoid eating or drinking near the books to prevent spills and stains. To maintain them, store the books in a dry and cool place. You can use bookends to keep them upright and prevent warping. If you notice any dust, you can gently wipe the covers with a soft, dry cloth.
