AMMM 5, 119-124 (without "Eia mater"); GASSER 2001, 543-545 (for "Eia mater"); MM 1 (see the records of the individual motets)
Further notes:
GASSER 2001 was the first to include Eia mater in this cycle. According to ROSSI 2019B, 391-393, and MM 1, xxx, this cycle does not include Eia mater, and starts with the motet Verbum sapientiae (I-Mfd 1, ff. 98v-99r).
