Mostly because this issue has not yet been addressed in this forum, I want to let people know that there are resources out there for finding nontraditional authors; or at least, there's one, which is the one that I'm involved with. In case anybody's interested :

...Okay, this is my plug. But we're attempting to educate people about daring and visionary writers, largely those whom you'll find very difficult to locate on the shelves of Borders and Barne's & Noble. This is important. We have a list of nontraditional and progressive authors (and information on them and their work, including pertinent links), the journals you can find their work in, and the presses (many small presses, some midline) who publish those works.

So... . If you're interested in finding out about a lot of the authors you're missing, check out the site. It's in a crude state, admittedly; we're working on it. But the primary intention is information. And during these days when Random House is gaining increasing influence over the outlets that carry literature, it is becoming increasingly vital that we, as a community, educate one another; for there're avenues, as I'm sure you all know, to circumvent the bookstore chains and Random House.

Also, for finding pertinent journals (both print and online), I've found Selby's List to be a very good source :
