Don't gild the lily. The author didn't want that narrow a market. So Comiskey did something which someday soon may come as second nature to aspiring authors. He put it on the Internet. What the Internet does is require any middlemen to truly add something of value.

I didn't need a publisher to take a risk. It became to me an obvious conclusion I didn't need any editor to tell me what I wanted to say, and I didn't need a publishing house if I wanted to get it out there. Those who download and copy the advice will be asked to send along ten bucks. But I trust everybody, be they lawyers or not lawyers. To me, there's no real risk at all.
