An information consultant is someone who helps people find information they need. Just like when you ask a grown-up for help finding something, an information consultant is like a grown-up who has a lot of experience finding information in books, on the internet, or even just by talking to people who know things.
Say you needed to write a report for school about pandas, but you didn't know much about them. An information consultant would be able to help you find books and articles about pandas, tell you where to look on the internet for information, and maybe even connect you with people who know a lot about pandas, such as scientists or zookeepers.
They might also help businesses or organizations figure out how to organize all the information they have so they can find what they need quickly and easily.
Overall, an information consultant is someone who is very good at finding and organizing information to help people and businesses be successful.
