I usually search before submitting: http://searchyc.com http://searchyc.com Most people don't bother, most people don't care. I put the cross-references because I don't like to see the discussion split between sites/submissions/pages. I prefer to see a coherent discussion in one place. There's no problem with submitting different articles about the same thing, sometimes the better article is only found later.
