Talk:NASA detects dry, dusty atmospheres on extrasolar planets

Question on using sources - The first paper I cite was published in Nature. I don't have access to more than the abstract at Nature. However, the full paper is available at arXiv.org, which is just an archive of papers. I cited the paper with the link to the full paper, but listing Nature as the publisher. Is that acceptable?

 * would be better to list both, identifying the respective publishers and marking the arxiv copy as a preprint (if that's what it is). takes care of the possibility that the arxiv version and the nature version are not identical. &mdash; Doldrums(talk) 05:44, 23 February 2007 (UTC)
 * If you use source-science, you can mention arVix as a database for the abstract.--Steven Fruitsmaak (Reply) 15:26, 23 February 2007 (UTC)
