In yesterday's New York Times, Motoko Rich's article Self Publishers Flourish as Writers Pay the Tab explains some of the basics of self-publishing. It can't be said to be comprehensive, as it doesn't mention Dan Poynter, but it makes some interesting points.

It uses the term "self-publishing company" for Print-On-Demand houses like iUniverse (what used to be called "vanity presses"), where I think it ought to explain a bit more for the sake of the uninitiated.

I didn't see any reference to those who do what I did, start a small press.
