According to NJ Spotlight, “In the state, there are 234 municipal libraries, 45 association libraries, 14 county libraries, and five joint libraries.” These libraries create tons of employment opportunities for librarians, as shown in the statistics. Another great thing about New Jersey is its high wages for librarians. Their living expenses are in the expensive range, though. Even so, their good employment rates still attract quite a lot of librarians.
