What is the difference between a library technical assistant and a librarian?

The differences between a library technical assistant and a librarian involve the level of required education and job responsibilities. Library technical assistants do not need formal training; their duties include support tasks, such as shelving books and assisting patrons, that can be learned on the job. Librarians typically have a master’s degree in library science and are responsible for creating a budget for the library, developing community programs, and selecting materials for the library.
