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collection of the pre-thirteenth-century deeds and charters of Yorkshire, which had previously remained largely unpublished.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. The majority of Volume 3 (1916) is devoted to the extensive charters of the Lascy fee of Pontefract and the Albermarle fee of Holderness. It also includes documents relating to Hallamshire and Mortemer. Each text is prefaced with a summary, and documents of note are followed by a discussion of their content and points of interest, including genealogies of the people involved.
