Librarianship is the job of helping people find and use information in a library. Diversity in librarianship means that there are many different kinds of people who work in libraries, and they all bring their own special skills and experiences to the job.
Just like how people can have different skin colors, speak different languages, or have different religions, librarians can also be different in all of these ways. And when there are many different kinds of librarians, it makes the library a more welcoming place for everyone who wants to come and learn.
When a library has diverse librarians, they can help teach people about different cultures and traditions. They might be able to speak different languages, so they can help people who might not speak English very well. And they might even have different hobbies or interests, which means they can help people find books or resources on topics they might not have thought about before.
Overall, diversity in librarianship is a really good thing because it makes libraries more interesting, more helpful, and more welcoming to all kinds of people.
