Joe: I hope you're not planning to shuffle off this mortal coil very
soon!! The UCSD library would probably like your books. I've made
donations to them (XHs, some scores from other composers). If you can
get a list together first, it would make donation easier and surer.
If UCSD doesn't want them, SDSU might. It would depend upon what they
already have, etc. Beyond that, I'd contact younger microtonalists at
institutions.
As for unpublished articles, scores, etc. I don't know-- many libraries
have space problems as I found out trying to donate journals to the
country library system.
