Notes: Data from NDL Attribution of "セント・ジョン" and "Ｐ・セントジョン" to {{a|Philip St. John}} from ameqlist as NDL (and OCLC which seems to copy their records) seems to have mistakenly attributed this to Patricia Mary St. John (an English missionary nurse who does not seem to have published any speculative fiction so a position on 少年少女科学小説選集 is highly unlikely)
