The Robert Spence Watson Collection is a collection of 500 volumes on the subject of English literature, consisting largely of the publications of literary societies such as the Shakespeare Society, the Spenser Society, the Ballad Society and the Chaucer Society, presented to the Library in 1908 by Robert Spence Watson, who was also one of the founders of the Durham College of Physical Science, and President of Armstrong College.

With three early twentieth century exceptions, the Indian Tracts is a collection of nineteenth century pamphlets on a range of Indian subjects, such as local self-government, the Indian Civil Service, education, politics, economics, transport, the trade of opium, religion and war.

The Grey Tracts reflect the interests of their former owner, the 2nd Earl Grey (1764-1845) whose Whig government was responsible for the 1832 Reform Act, 1833 Factory Act and the 1834 Poor Law Amendment Act. The pamphlets cover a broad range of historical, social and economic subjects including colonial policy, public finance and banking, the Corn Laws and agriculture, poor relief, slavery, Catholicism, Ireland and the Greek Revolution.

The Cowen Tracts are almost two thousand pamphlets which were formerly owned by local (radical) M.P., Joseph Cowen (1829-1900). The tracts date mostly from the mid- to late-Nineteenth Century and reflect Cowen's interest in the social, educational, political and economic issues of the day.

There is some earlier material, such as Deed of incorporation for the insurance of ships printed by T. Angus, St. Nicholas' Church-Yard, Newcastle (1778). Pamphlets were an effective form of public debate because they could be circulated to a wider audience than books and authors could remain anonymous. The Cowen Tracts discuss Irish politics, foreign policy, women's rights, religion, education and public health and include such titles as The Union programme for 1880: constructive, not destructive, Irish legislation [1879?], Are women fit for politics?: are politics fit for women [185-] and The education of the agricultural labourer: a paper read before the Morpeth Chamber of Agriculture, on Wednesday, Feb. 2, 1870 by M.W. Ridley (1870).

The Spence Watson's wide-ranging public activism, make their correspondence a valuable source of opinions on the social and political matters of the day from a wide range of prominent persons.

The papers of Walter Runciman, 1st Viscount Runciman of Doxford (1870-1949), relate chiefly to his political career, but also include material concerning his personal and professional life. They cover his election campaigns and his political career, during the years 1894-1938, and in particular they cover the different political offices he held, as a Liberal M.P. and Cabinet Minister, and as a member of the Board of Education, 1908-11, and the Board of Trade, 1914-16 and 1931-37. There is also material relating to Runciman's attempt to solve the 1938 Sudeten crisis through his mission to Czechoslovakia.The collection also includes the diaries and some correspondence of Walter's wife, Hilda Runciman, herself briefly an M.P. Hilda's diaries have been found to be of particular value to researchers, providing as they do an insight into the world and circles in which she and her husband moved, sometimes revealing insider knowledge about the current talk in London Society, a classic example being Hilda's remarks in her 1936 diary about the abdication crisis and the King's intentions. In addition, there are 114 volumes of press cuttings, plus material relating to Walter Runciman's father, the 1st Baron Runciman, as well as documents relating to Sir Walter Leslie Runciman (1900-1989).
