[6] Crossley published extensively and, in 1946, a study of Welsh rood screens he undertook in conjunction with Maurice Ridgway was awarded the G. T. Clark prize.
[9] He also undertook commissions for wood carvings and examples of his work can be seen in various churches in Cheshire at Over Peover, Bunbury and Plemstall, as well as the great roof of the Refectory at Chester Cathedral.
In 1932 he donated his large collection of negatives, totalling some 10,000, to The Courtauld Institute of Art in London where his photographs are held in the Conway Library.
[2][12] The importance of this collection and the significance of Crossley's contribution is cited by Fellow of the Society of Antiquaries of London, Charles Tracy, in the Society's journal Salon 219 dated February 14, 2020:The Conway Library is a unique visual cultural map of Europe from the early Middle Ages to the present day.
In my own field of church woodwork, the superb black and white photographs of Fred Crossley, to name but one early twentieth-century executant, constitute an invaluable record of the state of our church furnishings eight or so decades ago...[13]Plans and photographs by Crossley are held in other archives and collections, for example by the National Trust and in the Wellcome Collection[14][15] and photographs, by Crossley and his co-author Maurice Ridgway, of stained glass, rood screens and roofs of North Wales and border churches are held in North East Wales Archives.
