Ordinale Sarum, sive Directorium Sacerdotum: [Liber quem pica Sarum vulgo vocitat clerus] auctore Clemente Maydeston, sacerdote: Transcribed by the late William Cooke, M.A., sometime Honorary Canon of Chester.

The Directorium Sacerdotum is a sort of ordinal or directory for the Sarum Use, which though a private compilation by the Brigittine Clement Maydeston, acquired a de facto official status. The text here is taken from the quarto edition published by Wynkyn de Worde in 1495 (Duff, n. 294; GW 8460; STC 17724), and is furnished with indices. Vol. 20 in the present series is the first part, this volume is the second part.
