Prayer Book Society
"The Prayer Book Society was founded in 1972, in the heyday of liturgical reform in the Church of England, when it appeared that the 1662 Book of Common Prayer was in danger of being outlawed altogether. Happily, the Prayer Book was saved and continues to be used in a number of flourishing churches and most cathedrals, and the Prayer Book Society today continues to promote the worship and doctrine of the Church of England (and other churches in the Anglican tradition) as enshrined in the Book of Common Prayer. ...
"The Prayer Book Society is a Registered Charity and a Company Limited by Guarantee, and is largely run and managed by volunteers, with just a small handful of part-time paid staff. The Society has over 4,500 members representing a wide diversity of background, tradition and churchmanship, and including clergy, laity and organisations (such as PCCs) which have signed up for collective membership. Our Patron is HRH The Prince of Wales and our Ecclesiastical Patron is the Bishop of London (both keen supporters of the Book of Common Prayer)."
