Copy letter from Robert William Frederick Harrison, to the Managing Director, the Lecture Agency Limited, The Outer Temple, Strand, W.C. Harrison sends thanks for forwarding copies of the Date Book from 1906 to 1908, but believes it is published every year. He further suggests that the useful list of Mondays, given in 1906 and 1908, but not 1907, be included in all future editions. 3 July 1907
