You are providing a fantastic service. There are organ pieces I have been looking for for many years. I had found a few of them, but the copies were so beat up I couldn’t read them.
It seems that once a publisher goes through a printing and there are not many requests for the music, it goes out of print, or the publishing company folds or is sold to another company who then throws the originals out. What you are doing is preserving a legacy that needs to be preserved. Your copies are beautifully printed on good quality paper. Keep up the good work. Many thanks.
