This special issue of the Bulletin of the John Rylands Library is dedicated to Peter Nockles. An expert on the Oxford Movement and the religious history of the eighteenth and nineteenth centuries, Nockles was employed at the John Rylands Library from 1979 to 2016. During this time he extended his scholarly generosity and friendship to countless researchers. The issue features articles on a range of topics connected to Peter's scholarship and networks, including the Church of England (particularly High Churchmanship and the Oxford Movement), Catholicism, Methodism and Church-State conflict relating to the Church of Ireland.
