(Explanatory note.I used to be a writer and self-published about ten books in the mid-and late 20004s -- I had never even heard of Mail Art then. This became too expensive, so I turned to Art, and then to Mail Art, instead, mistakenly thinking it would be cheaper. It isn't. In 2009, I edited a book called 'Collections and Collectors' about the collections and collecting habits of a group of my friends. I wrote a chapter called 'Confessions of an analogue only digital man'. It might interest you in the context of this Group.
