[Temple] At a meeting of the First Presidency and Twelve held January 25th last, it was unanimously decided to ask each of the temples to keep a card index of the names of families for whom work is being done; also that a duplicate of each card be sent to the Genealogical Society of Utah that they, as a central office, may keep on file all information of this character for the use of those interested who are constantly making inquiry, and to aid the society in their work as well. The proposed card index will also [serve] another good purpose, that of enabling the different temples to prevent in future the duplication of temple work, as each temple, by this means, will be kept posted as to the names of the families for which work is being done in other temples. [Joseph F. Smith, Anthon H. Lund, and Charles W. Penrose to Lewis Anderson, Feb. 16, 1912]
