BENITA first appeared as a serialized novel, published in Cassell's Magazine, December 1905 through May 1906. Gordon Browne created 36 illustrations.
McKay, Scott, and Whatmore claim that Cassell and Company published the first edition in book-form in London on September 7, 1906. Apparently 15,000 copies were printed, with only 16 of Browne's 36 illustrations. Ads at the end of the book are dated-coded 6.06 (June 1906) for the Colonial Edition, and 7.06 (July 1906) for the London edition.
Higgins claims that Cassell paid £450 ($77,000 in 2020 dollars) for the serial rights, and £450 ($77,000 in 2020 dollars) as an advance for publication in book-form.
