My mother's uncle, Arno Schmidt, was a published author in Germany. It's a long story how she ended up with a small collection of his books, but a couple of years ago she decided she wanted to donate them to a university. I've been interested in archives, so I volunteered to help.
I wrote a blog post, got some interest, and in the end we donated the books to Portland State University. They had a scholar there who studied my uncle, so we felt we did a good job of finding a home for his writing.
