I just took a sh load of books and scores (yes! finally! scores!) to the dropoff place so they can be included in the local library sale this fall.
This was the easiest and run-of-the-mill stuff to donate, mostly opera vocal scores that were going to continue taking up valuable space without EVER being looked at again. Stuff that's easy to listen to and appreciate without following along. There is, of course, a host of "good stuff" that I'll never part with. But I need to lighten my burthen, and this helps immensely. I have other music that's more unusual and expensive that I'm willing to let go, but it needs to go to some individual or organization who I KNOW will have the appreciation and use for it. Not that that can ever be guaranteed, but I'll do what I can to get it to good homes.
