The University's School of History, Classics and Archaeology collection of the papers of Gertrude Margaret Lowthian Bell (1868-1926) consist of Gertrude Bell's letters to her family, her diaries and a number of miscellaneous items. The School also curates the photographic section of the Gertrude Bell Archive which includes several thousand of her photographs, mainly (though not entirely) of archaeological sites. This collection is of particular interest to scholars of the archaeology or the early 20th century history of the Near and Middle East.
In 2017, the Gertrude Bell Archive was added to the UNESCO Memory of the World Register in recognition of its global significance. It is one of only a few archives to be recognised in this way in the UK.
