Liber Facetiarum, published at Newcastle upon Tyne in 1809, is a miscellany of brief anecdotes, unusual incidents, witty remarks and stories concerning historical and contemporary figures. The collection ranges widely across social life, literature, religion, personal character and curious events, with individual entries designed to inform, amuse or illustrate memorable traits and situations.

The compiler places importance on the reported authenticity of the material and draws on numerous earlier authorities. Rather than developing a continuous argument or narrative, the book presents independent pieces that can be read separately, combining historical curiosity with entertainment. Some entries preserve sayings or stories attributed to notable individuals, including Benjamin Franklin, while others record eccentric behaviour, local traditions and humorous episodes. The work reflects the early nineteenth-century popularity of literary miscellanies that brought together instructive, surprising and amusing material for general readers.
