Libreria Musicale Italiana inaugurated the series Grooves: Edizioni di Musiche Audiotattili in 2011 with Jelly Roll Morton, la Old qaudrille e Tiger rag: Una revisione storiografica by Vincenzo Caporaletti. The book explores the longstanding question of whether Morton composed Tiger rag, which he claimed he adapted from an old quadrille, despite its having been copyrighted by Nick La Rocca.
