This is a somewhat unusual source post, as I don’t think any of the material here can be used directly for Art Song Central.
Nevertheless, The Internationale Stiftung Mozarteum has put what appears to be the complete works of Wolfgang Amadeus Mozart on their website:
They appear to be in high enough resolution to print legibly, but prints may still be a bit blurry.
Still, even if less than ideal for use in performance, this is a wonderful resource for them to make available!
