The papers of Mary Caroline Moorman (1905-1994), historian, biographer and daughter of the historian G.M. Trevelyan, cover the years 1872-1992. As well as usefully supplementing the Trevelyan Archives at Newcastle University Library, they are of considerable interest in themselves.

They mainly consist of letters from Mary Moorman's parents, George M. Trevelyan and Janet Penrose Trevelyan, née Ward. They also include some letters from Mary Moorman's extended family, such as Janet Ward's mother, the novelist Mary Augusta (Mrs. Humphry) Ward, her sister Dorothy and the Philips and Price relatives.

The Merz Collection is the mathematical library of John Theodore Merz (1840-1922), an electrical engineer. Merz also had an interest in philosophy, and the collection also includes books amassed by him during the writing of his work The History of European Thought in the Nineteenth Century. These 4000 volumes are strongest in Mathematics and the History of European Thought, but also include notable works on science, European history and German Literature.A particular highlight is An investigation of the laws of thought: on which are founded the mathematical theories of logic and probabilities (1854) by George Boole, the English mathematician and philosopher, and inventor of Boolean logic, the basis of modern digital computer logic.The collection is also of interest for its book-bindings: mostly leather or half-leather bindings by Zaehnsdorf of London.

This is a collection of over 2000 volumes and hundreds of pamphlets, covering the history of medicine and a broad range of medical subjects. The collection is rich in seventeenth, eighteenth and nineteenth-century works.

It includes books from the medical library of noted South Shields doctor T.M. Winterbottom (1766-1859), and highlights include Erasmus Darwin's Zoonomia (1794), John Abercrombie's Pathological and Practical Researches on Diseases of the Brain and Spinal Cord (1828), considered to have been the first textbook on Neuropathology, and several works by the famed botanist, humanist and physician Herman Boerhaave (1668-1738).

L.T. Meade (1854-1914) was the Irish daughter of a Protestant clergyman who later moved to London. She contributed short stories and articles to magazines such as The Strand Magazine and edited the periodical Atlanta but became better-known for her novels. She tried her hand at several genres, including crime fiction, but is most closely associated with stories which targeted a female audience, notably stories about girls' schools.

Meade wrote approximately 250 books and we have about 180 in our holdings which were published from 1878 and as recently as 2003. Titles include: The autocrat of the nursery, The children of Wilton Chase, Kitty O'Donovan, and The Scamp family. The collection was gifted to the Library by Jean Garriock.
