The compilation of this lists will never end. Daily there will be new music to insert. And every now and then there turns up pieces that are overlooked. As you will notice there are many data not specified. Birthes and deathes of mentioned composers, their nationality and the publishers or collectors of their music. If possible it is my aim to direct the reader as to where to find the notes or copies of them. It is my ideal to have a lifestory of each composer. There is yet much work to do on this topic. All the readers are enthousiastically invited to fill in any gap they can. My e-mailaddresses are mentioned in the first item of this Introduction.
