<human>: I'd like to learn about the different types of hats. Can you recommend some resources?
<bot>: I would recommend checking out this article on Hats and How They Work, which provides an overview of the different types of hats and how they are worn. Additionally, there are many books available that discuss various types of hats in detail, such as The Hat Book by David A. Hatch or The Art of Dress: A Cultural History of Headwear by Judith Thurman.
