Errant Story Volume One was carried in bookstores nation-wide, and was NOT self-published. It was published by Keenspot Entertainment, not Michael Poe, and it was carried by Perseus Distribution (cdsbooks.com) as well as Diamond. Later volumes may be published by a far more notable publisher, so there is every possibility that later volumes will be carried in bookstores as well. If it turns out to be necessary to have the article go away in the meantime, well... Wikipedia does have the right to make that decision, though I think it's oddly out-of-keeping with their mission statement.
Errant Story appears on Amazon.com, surely that is a sufficiently notable website? It is also still listed on Barnes and Noble's website, though it is shown as being out of stock. http://search.barnesandnoble.com/bookse ... 5075&itm=1
Additionally, Errant Story was to have been featured in an article about a webcomics show that I organized here in Cincinnati, at the Base Gallery. I believe that article was published in the Cincinnati Enquirer on Wednesday, August 17, 2005. There is an additional article from Wednesday, July 27, 2005 that someone might also check.
Also, the WCCA awards are from an organization, it says so on their website. Poe won lots of the things, if you go back and check their records. Personally, I don't think the awards hold much weight, but in terms of establishing notability, they ought to do. Millions of people know about them, so while they aren't the Oscars, they certainly are known. There's a difference between knowing and caring, but notability only requires that many people know of them, not that many people care.
Edit: I've adjusted my statement for greater accuracy, since apparently I'm going to be quoted in the argument. Someone correct my statement as listed on Wikipedia, please.
