The Post-incunabula collection does not strictly comply with the prescribed date range which often defines 'post-incunabula' but does contain English and foreign books printed 1501-1640. It includes works by John Stow, John Speed, Torquato Tasso and William Tynedale, as well as Robert Burton's The anatomy of melancholy, 4th ed. (1632), Holinshed's Chronicles (1587), Reginald Scot's The discouerie of witchcraft (1584), Palladio's architectural work I qvattro libri dell'architettvra (1581), Edmund Spenser's The faerie queene (1590-96) and Thomas Heywood's The hierarchie of the blessed angells (1635).

The Rare Books collection is miscellaneous but literature and local history are two of the collections strengths. Items date from the mid-Sixteenth Century to the present day (facsimile of The Arundel Choirbook, 2003). Particularly notable items include a German propaganda sheet which was dropped on England in 1940: Adolf Hitler, A last appeal to reason; Edward Jenner's Inquiry into the causes and effects of the variolæ vaccinæ (1798); various works by Charles Dickens which remain in their original serialised parts, complete with paper wrappers; herbals by Elizabeth Blackwell (1739) and Nicholas Culpepper (1802); a volume of printed ephemera, broadsides, posters and cartoons referring to elections in Northumberland, Newcastle and Tyneside divisions, including cartoons of Joseph Cowen (1826-1931) as well as some English Revolution (or Civil War) tracts and the manuscript Design no. 11 - Plans, specifications and estimates for building a chapel in the township of St. John, Newcastle upon Tyne by John Dobson (1840).
