Walter Wilson’s The History and Antiquities of Dissenting Churches and Meeting Houses (London, 1808–14, 4 vols.) is one of the gems that anyone researching seventeenth- and eighteenth-century Dissent needs to know. Going through vol. 1 just now, I noticed that among those whom Wilson consulted for help in his researches was “J. Sutcliff, of Olney.” Sutcliff, the Baptist pastor of Olney, was an ardent bibliophile and helping Wilson would have been right up his alley!
