This is likely the final version for each, though you won’t catch me swearing to that! Because, if anyone finds a typo, and tells me, I’d fix it.
I added to the rights page in each book, which is why both books got new versions. I am releasing my contributions via a CC0 1.0 Universal Public Domain Dedication. Find both titles on my uploads page at the Internet Archive.
Another ebook eventually arriving will be Midnight, by Rutherford Montgomery. It turns out, the copyright for this 1940 title was never renewed. Gutenberg.org has had an ebook available since 2019, digitized from the paperback version I used to own as a child! But that edition only had a single illustration, a frontispiece by Pers Crowell. I will be doing the first edition, 1940 Henry Holt and Company hardcover, fully illustrated by Jacob Bates Abbott.
