When you publish a book, you can publish some tags with it, to help people find it. I supplied some obvious tags like 'Raven' and 'nose', but it never occurred to me to tag the book: 'robinson'. It's probably too late now.
My interesting challenge is how to tell people to search for the book on Amazon.com. They will not find it if they search for my name, mis-spelling it Robinson instead of Robison. That's because I didn't 'tag' the book 'Robinson'. (Or maybe it's because I failed to take my mother's advice. She told me to change my name to Robinson.)
