This room holds the works of ʻAbdu'l-Bahá: his own books and tablets, among them the Secret of Divine Civilization, the Tablets of the Divine Plan and his Will and Testament, and the records of his talks and conversations, among them Some Answered Questions, Paris Talks and the addresses of his 1912 journey through North America collected in The Promulgation of Universal Peace. Bahá'ís regard his writings as the authoritative interpretation of Bahá'u'lláh's. Each page names its edition and quotes the Bahá'í International Community's terms of use under which it appears.
