BOT. numbers for works are provided in a book section: La Vita e le Opere. In Giovanni Bottesini: virtuoso del contrabbasso e compositore, by Luigi Inzaghi (1989). Rome: Nuove Edizione. These numbers are, however, quite useless as thematic catalogue numbers because different transpositions, arrangements, and even modern editions all get separate BOT. numbers. Therefore, they probably shouldn't be used in work page titles.
