They are offered in the spirit of rigorous scholarship and collaborative inquiry. I hold deep appreciation for the value of the original work and hope that these updates further its accuracy, utility, and enduring contribution to the field.</p><p dir="ltr">Published Khipu Data by Marcia and Robert Ascher:</p><ul><li>Ascher, Marcia and Robert Ascher. 1972.
