The transition from working in either a special library or corporate information center to an academic library requires some adjustments. The least adjustment is the change from chemical information specialist to chemistry librarian in a dedicated chemistry library primarily used by advanced chemistry students and chemistry faculty. Most librarians, however, must either serve in multidisciplinary science libraries, or become science specialists in single campus libraries. In such situations librarians may face new responsibilities. Generally, librarians teach more in academic libraries, often to novice library users. They may teach credit bearing chemical information courses. Some academic librarian positions carry faculty rank with its accompanying perks, such as tenure and generous vacation, and accompanying responsibilities, such as the requirement to publish and perform service to the greater library community. Most librarians can be content in both academia or industry.
