Partitura Organum is a growing collection of organ music editions.
I create quality scores of lesser known organ music from original printed or manuscript sources in the public domain.The scores are released under the terms of the Creative Commons Attribution Non-commercial ShareAlike License, CC BY-NC-SA 4.0 International, which can be found at creativecommons.org. The scores are freely available on my website.
Your support will enable me to continue to create scores and make music freely available that is not commercially available or only available in rather expensive editions.
And as an extra you can commission me to create a score of a piece of music of your chosing. The only condition is that the source material (be it manuscript or old edition) is in the public domain.
