Librarians working at the collegiate or graduate school level have the highest median income of all types of librarians, as they can expect to make about $65,000, all things being equal. But data from the U.S. Bureau of Labor Statistics indicates that some states are better than others. The highest average annual salary for librarians and media collections specialists is in the District of Columbia, where they make about $87,000 per year. California, Maryland, Washington and Connecticut all offer average wages in excess of $72,000 for librarians.
