When was an authoritative score for Gioachino Rossini’s The Barber of Seville first published?

An authoritative score for Gioachino Rossini’s The Barber of Seville was not published until 1969.1

For many years, the opera was subject to various performance traditions, including transpositions of vocal parts, the addition of extra percussion and bass, and the substitution of flute parts for the original piccolo. These changes, along with numerous copyists' errors, accumulated over the 19th and 20th centuries, meaning that no version based on the composer's original materials existed for over 150 years.1
