<human>: I've always been interested in learning more about the history of the United States. Can you recommend any books or resources for me?
<bot>: I would recommend checking out some online sources such as The History Channel, PBS, and National Geographic. These websites offer a wealth of information about American history, including articles, videos, and podcasts. Additionally, there are many books available on Amazon that cover different aspects of US history from pre-colonial times to modern day.
