Harvard provides many resources for its undergraduates. An extensive advising network helps students navigate their academic and residential lives. Students have access to extraordinary academic resources, including the world's largest university library, more than two dozen buildings dedicated to scientific research, and many University museums. Students exploring career options can receive guidance and assistance from the Office of Career Services and the Student Employment Office. There are also offices and groups that address students' health, safety, as well as technological needs. But perhaps the most valuable resource that Harvard offers is the opportunity for formal and informal relationships with Harvard's faculty and interactions with a diverse and talented undergraduate student body.
