The papers and photographs of Gertrude Bell mainly consist of the letters Gertrude Bell sent home to her family whilst on her travels, of the diaries she kept when abroad, and the photographs taken whilst she was away.

The papers consists of sixteen thousand letters, sixteen diaries, seven notebooks and forty-four packets of miscellaneous material; whilst the photographic collection is about 7000 in number, and consists of photographs taken by her between c.1900-1918. Those of Middle Eastern archaeological sites are of great value because they record structures which have since been eroded or, in some cases, have disappeared altogether, while those of the desert tribes are of considerable anthropological and ethnographical interest.

Her competence as a field archaeologist and photographer means that the papers are indispensable for archaeological research of parts of the Middle East.

The items in the Bell Miscellaneous Papers contain material relating to Bell's work and travels, including contemporary articles, notes by Bell on various topics (archaeological sites, Arab tribes, etc.), letters concerning the publication of Bell's letters by Lady Richmond and letters to and from Gertrude Bell, maps and plans, literary manuscripts, lecture notes and copies of letters from Gertrude Bell held elsewhere. There is also a series of the letters known as the Doughty-Wylie letters, 1913-1915. These are the letters between Gertrude Bell and Charles Doughty-Wylie, an army officer with whom Bell was in love. The letters were returned to Gertrude Bell after his death at Gallipoli in 1915.

Papers primarily relate to Wilcox's time in Germany and Russia and mainly consist of typescripts (some annotated/edited) and offprints of articles published in contemporary journals. These include, for example, versions of a series of articles on Kerensky and Korniloff from the Fortnightly Review (September 1918-January 1919) and the subject's response. There is also a large collection of foreign-language articles and pamphlets (some by Wilcox), including B.V. Savinkov's Za rodinu i svobodu (Warsaw, 1920).

Bentley was a journalist, author of Trent's Last Case, and inventor of the clerihew poem, and remained in contact with Wilcox for many years, although there are no extant letters later than 1923.

Consists of fifteen diaries of William Brewis of Mitford, and two items of contemporary published material relating to the diaries.

There is one diary for every year between January 1833 and January 1850, aside from 1835, 1836 and 1844. These provide a first-hand account of rural life in the Morpeth and Ponteland districts, as Brewis describes visits to hiring fairs and markets, current sale prices for crops and animals, and farms available to rent. He also regularly observes weather conditions, which were unusually severe between 1837 and 1855 due to the advance of Icelandic glaciers, and their effect on the growing seasons and harvests. Brewis remarks on how his farm is affected by a ‘distemper’ amongst the livestock, similar in nature to an outbreak of foot and mouth disease, as well as his own illness during the outbreak of influenza in 1837.

Brewis documents dining with leading members of the community and gives an insight into the relationships between farmers, local landowners and businesses in the area. His diaries make note of events in the local community including the execution of Ralph Joyce, a 24 year old man charged with the murder of his own father who was hung in Morpeth gaol in 1846.

Like many other farmers of the time, Brewis took a keen interest in national and international news. In his diaries he notes and makes frequent comments on national political and societal events. These include the death of King William IV, whom Brewis was fond of, and the marriage of Queen Victoria and Prince Albert, whom Brewis often criticised. There are also entries on Chartism and the Chartist rising in Newport led by John Frost, as well as notes on India and the war against the Sikhs in April 1846.

The Local Illustrations date from the Eighteenth and Nineteenth Centuries and depict a variety of local scenes and structures, such as schools, hospitals, residences, castles and churches. There are views of Newcastle, Durham, Northumberland, Sunderland; portraits; depictions of local life (keelmen playing cards) and a plan of the Grainger Market, Newcastle.
