Imagine you’re trying to plan a trip to Hawaii. You’ve got a few pictures of beautiful beaches, a list of things you want to see, and a rough budget in mind. How do you pull it all together? You might browse travel blogs, compare prices, and even watch videos of the islands. You’re using different kinds of information – pictures, text, and video – to make sense of your trip.

Do you read a lot? No? Well, let’s say you’re at a library looking for information on a specific topic. Instead of just browsing through every book on the shelves, you ask the librarian for help.
