> Around the same time, scans of Beethoven manuscripts began to appear on a wiki site for musicians called the International Music Score Library Project. IMSLP is the third wonder of the crowdsourced world, after Wikipedia and OpenStreetMap. I write as an OSM OG, someone who in theory understands crowdsourcing dynamics more than most, and still... IMSLP never ceases to amaze me. One example. Look at the contributions of Pierre Gouin: https://imslp.org/wiki/Category:Gouin,_Pierre https://imslp.org/wiki/Category:Gouin,_Pierre . He's 77 years old and from Montreal. He has edited thousands of scores of keyboard music, with the highest standards of scholarship, and posted them up for people to download. I play the church organ and I lose count of the number of times I have benefited from his endeavours. Multiply that by the number of IMSLP's dedicated contributors. Multiply that by the number of musicians who have downloaded their scores. It is an absolute wonder and it deserves more recognition.
