I've been working on archives, getting ready to retire my last Manila server.
One of the sites I was reviewing had a letter written by Thilo Ernst, a scholar who has read the writing of my long-gone great uncle Arno Schmidt, who was a German novelist. I read this letter with new eyes, 12 years after it was written. My blog writing is just as described in the letter.
It doesn't become a book, unless you subscribe to Arno's theory of what books are. Then any random collection of blog posts would make a wonderful book.
I think Dr Ernst is right, I would have had an interesting time talking with Arno.
Maybe in the after life.
