I suppose I look at it like, if one is interested in bettering themselves and wishes to take a look at one of AC's, or another author's books, especially one of free publication, it's a good idea.
If they like it enough or think they can really benefit from owning a copy, they will buy one.
It's always nice to have a book in print, isn't it. Even old books smell like good times. I bet thousands of year old books smell good. Like a healthy blast of dmt from a glassware pipe. That's what it's always smelled like to me though. Like a graveyard of old books of living language.
