Extensive collection of lantern slides (ca. 2,500) and negatives (ca.1.800), together with papers (excavation notes, correspondence, texts of lectures, working notes), some published guidebooks, and a few photographic prints. The photographic collection chiefly relates to Romans' interests in church architecture, and pre-Conquest stone sculpture, particularly in the north of England, but also includes material reflecting his interest in Roman archaeology and architecture. Many of the photographs were taken by Romans himself, but the collection includes numerous lantern slides by other photographers, some obtained from friends and others probably through Romans' membership of an exchange club. The papers include material on the excavations in which Romans participated at Birdoswald, Malton, Brough by Humber and Old Durham.
The photograph albums and accompanying loose papers reflect Romans's tremendous interest in and knowledge of church buildings. They include a quantity of loose photographs, newspaper cuttings about church buildings, and more general historical sites, lectures on biblical, ecclesiastical and local history topics, extracts from Staindrop parish registers (in connection with his study on Staindrop church and parishioners, and a catalogue of the Kepier library in Houghton-le-Spring.
