With Lincoln in the White House:

"For this volume, Michael Burlingame includes all of Nicolay's memoranda of conversations, all of the journal entries describing Lincoln's activities, and excerpts from most of the nearly three hundred letters Nicolay wrote to Therena Bates between 1860 and 1865. He includes letters and portions of letters that describe Lincoln or the mood at the White House or that give Nicolay's personal opinions.

He also includes letters written by Nicolay while on troubleshooting missions for the president."--BOOK JACKET.
