  Passage: The University of Oxford has 38 Colleges and six Permanent Private Halls (PPHs) of religious foundation.  Colleges and PPHs are autonomous self-governing corporations within the university, and all teaching staff and students studying for a degree at the university must belong to one of the colleges or PPHs.  These colleges are not only houses of residence, but have substantial responsibility for teaching undergraduate students.  Generally tutorials (one of the main methods of teaching in Oxford) and classes are the responsibility of colleges, while lectures, examinations, laboratories, and the central library are run by the university.  Most colleges take both graduates and undergraduates, but several are for graduates only.
  Title: List of Honorary Fellows of Keble College, Oxford
  Passage: Keble College is one of the constituent colleges of the University of Oxford.  It was founded in memory of the Anglican clergyman John Keble, who died in 1866, and was intended to cater for men whose financial resources were insufficient to enable them to study at one of the older Oxford colleges.  After a public appeal for donations in John Keble's memory, the college opened in 1870.  The college's buildings – which were quite unlike any previous Oxford college, with their use of coloured bricks in patterns – were designed by William Butterfield; there have been later additions as the college has grown.
