"Supplemental Nights to the Book of the Thousand and One Nights — Volume 3" by Richard Francis Burton is part of a translation series published between 1886-1888. This volume belongs to Burton's seven-volume supplement following his complete translation of the Arabian Nights. Burton's work became notorious for its unexpurgated content and extensive commentary on Oriental customs and sexuality. Published as a private subscribers-only edition to avoid Victorian obscenity laws, these volumes sparked both admiration and controversy, including accusations of plagiarism and criticism of Burton's archaic style and obsessive annotations.
