Sally Carson 21 December 2010 Thanks for your response Simon. For those of us who are already familiar with Leborg’s work, it lends you and this publication more credibility to give more explicit citations. Including him in Further Reading is not the same as citing him under his recreated diagrams. If this were a printed publication, you would be held to more stringent guidelines, so I think it’s a shame if we shrug that off because this is “just” the web. Thanks for responding, I think readers will benefit from our back-and-forth.
