Bibliometrics is a way of counting how many times people talk about books, articles and other things that academics write. It's like counting how many candies you have in your candy jar or how many toys you have in your toy box.
When your teacher writes a book or an article, other teachers might read it and talk about it. They might even write their own books or articles based on what your teacher wrote. Bibliometrics helps count all those times that people talk about your teacher's work.
It's kind of like when your mom or dad tells their friends about something you did at school, and then their friends tell their friends, and then more people start talking about it. Bibliometrics is like counting how many people are talking about what you did.
Some people use bibliometrics to see how important or popular a particular author or paper is in the academic community. It can help scientists figure out what research is popular in their field, or what they need to focus on next.
So, just like how you count your toys or candies, bibliometrics helps people keep track of how many times people talk about books and articles so they can understand what's popular and important.
