The Denham Tracts constitute a publication of a series of pamphlets and jottings on folklore, fifty-four in all, collected between 1846 and 1859 by Michael Aislabie Denham, a Yorkshire tradesman. Most of the original tracts were published with fifty copies (although some of them with twenty-five or even thirteen copies). The tracts were later re-edited by James Hardy for the Folklore Society and imprinted in two volumes in 1892 and 1895. It is possible that J.R.R. Tolkien took the word hobbit from the list of fairies in the Denham Tracts.
