At the start of term all freshers (students who have just started their first year at university) sign the Admission Book. This is a requirement set down in the college ordinances (regulations). At the same time students complete matriculation forms for the University. This is the formal process of enrolment.
No admission books of any kind survive before 1560 and records of admissions to the College only survive from 1635. The oldest extant book records the admission of Master, Fellows, Scholars, Officers and preachers for most of the period 1560-1759. This includes the admission Trinity’s famous alumnus, Isaac Newton, in 1667. This year’s freshers have had the opportunity to see this signature when they have come into the Wren Library to sign the current Admission Book.
