I agree George about the importance of indexing.
I have had a situation recently where some wonderful archive concertina playing was found.Some of the best concertina playing I have ever heard,but the artist(s)name is unknown, the type of concertina being played is not certain.There is one person in the World who may know who this or those players are,but he cannot be found and may not even be alive.
(Maurice Harvey just in case he reads this).I have made a decision that these recordings are going to be used so others may hear them and be listed as unknown artists on the CD,but these recordings were only made in the fifties.
A number of people do research on artists,types of music,Music Hall etc and one hundred years from now someone will be jumping up and down with glee to find some of the stuff we now take for granted.
I must mention here the sound archives of The British Library who have a wonderful collection of old and new recordings and every effort should be made to support this cause.A copy of the CDs for the projects I am working on will be going FOC to the Library.If you are researching music ,start there.
