The University Library section of the University of London Archive came into its own when Karen Attar lectured on ‘The University of London Library during the Second World War’ (the University of London Library being Senate House Library’s name at the time). The talk drew heavily on Library Committee minutes and annual reports, library office correspondence, and on more personal documents. The recollections, written in 1966, of a member of staff who worked in Senate House throughout the war and remembered such things as everyone getting plenty of exercise because the lifts did not work for months on end, provide a fascinating personal glimpse into the period. The official library diary records the sorts of reference enquiries received, and describes clearing up after air raids, and trespasses from members of the Ministry of Information among other details. Just how important the Archive is for uncovering such insights will become apparent when the talk is published.
