Librarians mainly sort out documents, classify working documents for reference and so on. It's still relatively easy. However, this is a comprehensive occupation and things are complicated, so friends who have no foundation or poor foundation suggest that it is better to go to an architectural school for training. I recommend building a university. I am a documenter studying here. The teacher is very responsible for us. I like this kindness. There is no teacher's shelf. And the one above. I consulted several schools at first. The staff school says there is no such course. How can there be now? It seems that I learned a little later than you.
