Linz 290 contains a monastic breviary from Kremsmünster. It dates from the twelfth century, with later additions. The additions are noteworthy, however; they include text and music for the Lamentations, as well as differentiae for Christmas, the Octave of Christmas, Epiphany, and Triduum. (Differentiae appear only for these Offices in the manuscript, and are numbered arbitrarily in the index.) The Offices for Mary Magdalene (thirteenth century) and Benedict are also later than the main body of the manuscript. The Benedict Office is a rhymed Office written over the earlier Office; the latter is included in an introduction to the published version of this index prepared by Martin Czernin but it is the later, rhymed Office which is in the CANTUS index as it is the one visible in the microfilm of the manuscript. Full texts for the Office are available in Analecta hymnica, vol. 25, pp. 145-9.
Because the notation consists of non-diastematic neumes, mode is impossible to determine for antiphons; however, an attempt has been made to match the neumes given for responsory verses to the modal formulas for such chants, so mode is included for responsories whenever possible.
