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of the pre-thirteenth-century charters and related records of Yorkshire, which had previously remained largely unpublished.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 7 (1947) is devoted to the honour of Skipton, and covers the family of Cecily de Rumilly, founder of Embsay Priory. Breaking from Farrer’s original scheme, the Latin texts here extend into the first three quarters of the thirteenth century to form a coherent group relating to Skipton. Each text is accompanied by notes and discussion of points of interest. The volume also contains detailed indexes.
