The medical tracts contain a series of 129 bound volumes of pamphlets relating to medical matters. These matters include, but are not limited to, addresses from the Royal College of Physicians, along with new research and hypotheses about ailments, symptoms, consequences and cures. There is also a small collection of 'History of Medicine' quarterly magazines, and the occasional instance of a stand alone pamphlet, such as 'Four Centuries of Anatomy,' by Frederick Pybus, A professional biography of William Harvey, and the '1st spasmodic cholera epidemic in York,' published by the Borthwick Institute, York.

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).
