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of the pre-thirteenth-century charters and related records of Yorkshire, which had previously remained largely unpublished.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 8 (1949) focuses on the honour of Warenne. As Farrer's original notes on Warenne contained only forty-five charters, Clay expanded the range of the present corpus to include texts up to 1240, and charters of the lord of the honour. Each Latin text is accompanied by English notes and discussion of points of interest. This volume also contains facsimile plates of select documents as well as detailed indexes.
