The original of "Some Answered Questions" in Persian is preserved in the Holy Land; its text was read in full and corrected by ‘Abdu'l-Bahá Himself. Unfortunately, Abdu'l-Bahá did not read and authenticate all transcripts of His other talks, some of which have been translated into various languages and published. For many of His addresses included in "The Promulgation of Universal Peace" and "Paris Talks", for example, no original authenticated text has yet been found. However, the Guardian allowed such compilations to continue to be used by the friends. In the future each talk will have to be identified and those which are unauthenticated will have to be clearly distinguished from those which form a part of Bahá'í Scripture. This does not mean that the unauthenticated talks will have to cease to be used -- merely that the degree of authenticity of every document will have to be known and understood.
