librarianship

answer: 

You need a master's degree from an ALA accredited school for some library jobs, but not all of them. You generally need a bachelor's degree to get into a library master's degree program, but it does not matter what subject you majored in in college. My library school had people who studied everything from accounting to ancient Greek.
