Self-publishing is a totally legitimate method of getting your work out there. WAV's assertion he is published is correct. He (or anyone else for that matter) can publish his work through any number of media and they don't need permission from anyone, they don't need an ISBN and they don't need to meet any particular criteria.

Anyone who knows owt about poetry will know self-publishing is a common way of getting work out there, and the internet is an equally valid way of publishing. Individual poets and artists often print and issue their own work as it's cost-effective and they can be far more creative on small runs that can be finished as wished without editorial or financial restraints (a bonus as most self-publishers can't afford much anyway).

Did Winstanley have an ISBN when he issued his pamphlets in the face of Cromwell's oppression? Did that make his publications less legitimate? Should Ian Hamilton Finlay have abandoned the Wild Hawthorn Press because he printed all his works himself? Perhaps the resistance should have stopped publishing Défense de la France because it wasn't sanctioned by the Nazi's? There is a vibrant artistic and political community that continues to self-publish in all forms of media and long may it do so. Although not everything published is either good and may well be execrable in any number of ways, it is still an very important creative outlet.

Whatever stick you decide to beat WAV with, this one ain't it.
