sentences:  The RCHME worked closely with the NBR to carry out the extensive photographic recording of the towns in the eastern and southern counties at risk from enemy action.Although there were other voluntary and academic bodies at the time that collected some architectural records (including the RCHME, the Royal Institute of British Architects and the London Survey Committee), they were apparently deemed to be too small or narrowly focused for the sort of comprehensive venture that seemed necessary in the chaos of wartime Britain.The initial core of the collection was formed by the Conway Library of architectural photographs held by the Courtauld Institute of Art; the negatives of the Victorian photographer Henry Taunt of Oxford; items from the University of London and by quickly setting photographers to work recording buildings in London and other vulnerable areas.
