Nov. 27, 1924 -- The Guardian approved suggestion by Horace Holley to create Baha’i Year Books

The suggestion made by my dear and able friend, Mr. Horace Holley, as to the compilation of an annual " Bahá'í Year Book" is extremely valuable and timely. I am much impressed by it, and feel that an immediate start should be made. I believe it can best be now undertaken under the direction and supervision of your Assembly until the time should come for the friends in the East and particularly Persia to participate effectually in its development. I trust you will send me a copy of the skeleton of the material you propose to include, and I shall here attempt to fill up any gap and render any assistance I can to make it as comprehensive, as attractive, and as authoritative as possible. (Shoghi Effendi, 'Baha'i Administration')
