I am working on Anna E. Dickinson Family Correspondence. The section I am currently working on is 1882:Sept 6 - Dec 25. Based on the letters' content (midwest tour with managers Wentworth and Hunting), it appears that that pages 2-46 took place in 1883. (Anna makes hers "3s" very strangely so that may be why they are miscategorized).
Pages 47 thru 51 are from 1882, so they are in the correct section..
