The CURSUS project, funded by the Arts and Humanities Research Board (AHRB), aims to produce online editions of the major surviving sources of the medieval English Benedictine Office liturgy prior to the Reformation. The project ran from May 2000 with AHRB funding until September 2003. The editions of the sources, which comprise both manuscripts and early printed books, will be encoded to highlight the different types of liturgical text whether breviary, missal, hymnal, antiphoner, or portiforium, and then the different genre of text within each (e.g. chants, prayers, biblical and hagiographical readings, homilies). The electronic texts were encoded with a TEI P4 extended variant. The Web site includes information about the project (sources and methodology), editions of the manuscripts, a version of the vulgate used for lectio, and centralised repository of all antiphons/responds/prayers containing the Corpus Antiphonalium Officii.
