Library science sounds very narrow, and the actual employment is quite wide. You know, it's almost information management, and it has high requirements for professional English and computers. Even if I don't want to go to the library in the future, it's easy to do other things.
I majored in library science and immediately went to the graduate school of information science. Actually, it's good to learn information. Our teacher said that the employment of information science should be wider.
You can think about it a little. In fact, I think it is better for graduate students to study another major if they have the ability, which is good for broadening their skills.
