• Same problems as the book chapter on Seondeok in presenting details from Sheri Holman's novel Sondok: Princess of the Moon and Stars (2002 Scholastic) without credit to Holman or adequate notice of the fictional content

• Yung-Chung Kim, Women of Korea: A History from Ancient Times to 1945 2nd ed. (1977)
  • Index of Queen Sonduk references: 23, 24, 27, 42 (Apparent mistake for 25, 26, 27, 42)

This book does not appear to have any mention of Seondeok's passion for astronomy, her having a Tang ambassador as a tutor, etc. See wok_transcript.
