Comments: Might be the fewest scheduled releases of any month since this site began operation.
1 - These monthly release lists are not meant to be exhaustive compilations of non-fiction releases. They do not include reprints that are not significantly revised/expanded, special editions not distributed to reviewers, children's books, and digital-only titles. Works that only tangentially address the war years are also generally excluded. Inevitably, one or more titles on this list will get a rescheduled release (and they do not get repeated later), so revisiting the past few "Coming Soon" posts is the best way to pick up stragglers.
