Rybicki suggests that this raises the question as to the extent of Mrs. Curtin's contribution to the various works by her husband. While characterizing Curtin's translations as "mediocre", he suggests this might have been something of a collaborative effort by husband and wife. Rybicki compared the "Memoirs" with other Curtin works and found that the two books on the Mongols, written after Curtin's death, were stylistically more similar to the "Memoirs", while the Native American mythologies are least like the "Memoirs". Rybicki also found similarities in two translations: "Przez stepy" ("Lillian Morris") and "Za chlebem" (For Bread). Rybicki concludes, "the corrections she introduced could be quite far-reaching".
