So, you know how you love reading books and magazines, right? Well, there is somebody called a periodicals librarian who helps people find and read magazines and journals in a library.
Imagine going to a big store with lots of shelves with magazines and newspapers of all kinds. It would be a bit difficult to find the right one for you, wouldn't it? That's where the periodicals librarian comes in! They help you find the right magazine or journal you need for your research or just for fun.
You can ask the librarian to show you where the magazines are and they will help you pick the right one. They know where each magazine belongs and can tell you which shelf they're on. If you need help finding a specific article in a magazine or journal, the periodicals librarian can help you with that too!
In short, a periodicals librarian is a helpful person in the library who knows where all the magazines and journals are and can help people find what they need.
