English Dialect Dictionary
The English Dialect Dictionary, being the complete vocabulary of all dialect words still in use, or known to have been in use during the last two hundred years; founded on the publications of the English Dialect Society and on a large amount of material never before printed was published by Oxford University Press in 6 volumes between 1898 and 1905. Its compilation and printing was funded privately by Joseph Wright, a self-taught philologist at the University of Oxford. Vol. 1: A-C; Vol. 2: D-G; Vol. 3: H-L; Vol. 4: M-Q; Vol. 5: R-S; Vol. 6: T-Z, supplement, bibliography and grammar. The content was issued progressively as 28 parts intended for binding into the six volumes with publication dates of 1898, 1900, 1902, 1903, 1904 & 1905. Vol. 6 includes an invaluable list of writings in dialect arranged by counties.
Due to the scale of the work, 70,000 entries, and the period in which the information was gathered, it is regarded as a standard work in the historical study of dialect. Wright marked annotations and corrections in a cut-up and rebound copy of the first edition; this copy is among Wright's papers in the Bodleian Library at the University of Oxford.
