I've gone through Moonlight Reader's 1001 books list and identified those entries that are historical nonfiction but currently not yet also on Chris's History Nonfiction list. Please have a look at the below books you contributed to MR's list and let Chris and me know whether you want them to be added to Chris's list as well.
(@Elentarri, Markk and Tigus: I directly compared the two master lists without referring back, for each individual book, to your original submission posts. So apologies if any of the below are already part of your submissions for Chris's list after all.)

For purposes of reference: Chris's list includes scholarly and popular historical nonfiction, as well as such things as first hand accounts (diaries, autobiographical writings, interviews, etc.) and other major primary historical sources, scientific, technological and cultural history, and narratives of the fairly recent past (approximately up to the 1990s). On that basis, all of the above-listed books would fit in one context or another.
