content: None of these books were written in the 1980s (disregard the 1966 typo, should be 1866). They're direct reprints of books from around 1900. The originals are stored in the Library of Congress, which is what the 1980s print was copied from, so I have zero doubt about it's authenticity. Even the font size and page numbers match up between my version and the original version on Archive.org. As for books in the 1980s, that's exactly why I bought these ones, because they were originally published within the years following the Civil War. Hell, the Rebel Clerk's Diary was published a year after the war ended.
