The 2004 edition of the "Music Publishers' International ISMN Directory" appeared at the end of 2003. Although the MPIID had been conceived as a yearly publication, K. G. Saur publishers decided to refrain from a 2005 edition for two reasons: first, the copies of the 2004 directory did not sell as expected and, second, the International ISMN Agency had to declare that it is not in a position to finance all editorial work for the publishing house any more. Negotiations about the future of the MPIID were scheduled for 2005
