So basically Hollywood is like a giant library where people who make movies and TV shows can go to find information. Inside Hollywood, there are lots of little sections like shelves in a library. Each section has information about different things like actors, directors, movies, and TV shows.
When someone wants to make a movie or TV show, they go to Hollywood to find out who are the best actors and directors to hire. They can also look at past movies and TV shows to get ideas and see what has been successful before.
But unlike a regular library where you can just go and check out a book, Hollywood is a secret library that only certain people are allowed to access. You have to be part of the movie or TV industry to get in.
So, Hollywood is like a very big secret library that only people who make movies and TV shows can use to find information and inspiration for their work.
