Okay kiddo, so Wiley is a company that makes books for adults. They publish books about all sorts of things like science, history, and even stories that people like to read. They also make textbooks for students to use in school. Wiley has been around for a very long time, since 1807! They have lots of smart people who write the books and then they print them and sell them to other people who want to learn about those things. So, it's kind of like they are a really big library that creates their own books!
