Twain's "Battle Hymn" online at Wikipedia.org is an example of two problems the organization has because of its open and unrestricted editorial model. They have the title wrong -- it was not "Updated" but "(Brought Down to Date)" -- and although written in 1901, the piece was not published until 1958 and, so far as I know, is still covered by copyright. I'd guess that there are many more pages like that in Wikipedia and that the case the New York Times covered is only the tip of the iceberg of potentially criminal acts by Wikipedia contributors. I had an experience with copyright violation there a few months ago. Someone copied one of my articles about an anti-imperialist writer into Wikipedia and, as an afterthought, sent me the URL of the article at Wikipedia and asked if it was OK to leave it there. I told him to remove it, and he did, but that made me wonder how many other contributors to Wikipedia are actually contributing other people's writings. Jim Zwick
