The university is made up of a variety of institutions, including 38 constituent colleges and a full range of academic departments which are organised into four divisions.All the colleges are self-governing institutions as part of the university, each controlling its own membership and with its own internal structure and activities. Being a city university, it does not have a main campus; instead, all the buildings and facilities are scattered throughout the city centre. Most undergraduate teaching at Oxford is organised around weekly tutorials at the self-governing colleges and halls, supported by classes, lectures and laboratory work provided by university faculties and departments.
Oxford is the home of the Rhodes Scholarship, one of the world's oldest and most prestigious scholarships, which has brought graduate students to study at the university for more than a century.The university operates the world's oldest university museum, as well as the largest university press in the world and the largest academic library system in Britain. Oxford has educated many notable alumni, including 27 Nobel laureates, 27 Prime Ministers of the United Kingdom, and many foreign heads of state.
