Volume 23, the penultimate volume in Series II of the complete edition contains free arrangements by Liszt dating from between 1859 and 1861. The best-known among these are the three Verdi opera fantasias: the Miserere du Trovatore, Ernani and Rigoletto, together with the two Wagner transcriptions: the Spinnerlied aus Der fliegende Holländer and the Fantasiestück über Motive aus Rienzi. The volume also contains two transcriptions each from Berlioz and Lassen, and one each from Bach, Meyerbeer and Dietsch. An interesting addition is the early version included in the appendix, which represents an important basis for study of the genesis of Ernani.
