This thirteen-volume series, which first appeared between 1914 and 1965, is an extensive collection of the pre-thirteenth-century charters and related records of Yorkshire, which had previously remained largely unpublished. The first three volumes were edited by William Farrer (1861–1924), after whose death Charles Travis Clay (1885–1978) took up the task. The series was well respected for the quality of Farrer's editing, which was surpassed only by that of Clay in the later volumes. Volume 1 (1914) contains nine pre-Norman documents, with extensive commentary by the historian and philologist William Henry Stevenson (1858–1924). It also contains royal charters and deeds relating to the city of York, arranged by barony. Farrer has attempted to provide a date for each document, and has added extensive annotation throughout which relates to the content, background and manuscript sources of the Latin texts.
