This thirteen-volume series, published for the Yorkshire Archaeological Society between 1914 and 1965, is an extensive collection of the pre-thirteenth-century deeds and charters of Yorkshire, which had previously remained largely unpublished. The first three volumes were expertly 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 only surpassed by that of Clay in the later volumes. Volume 10 (1955) is devoted to the Trussebut Fee, but also contains texts related to the Ros Fee. As he has done elsewhere, Clay has expanded the scope of this corpus to include some early thirteenth-century documents. The texts presented here are accompanied by notes and discussion of points of interest. The volume also contains facsimile plates of select documents, and detailed indexes.
