Report On Your Surroundings
When you report back to the mysterious person, they seem very pleased by your efforts. They now want a short write-up of your experience -- after all, you're bound to have a favorite library or two, and they want to hear about it!
Your assignment is to write at least 100 words about your favorite library. Why is it your favorite? Did you find useful resources that you didn't know about already? If you have more than one favorite, cool! You can write about that too -- just make sure you write at least 100 words about each library.
