Nature Publishing allows article viewing and sharing

Nature has made research articles in all of its journals free to read without a subscription. Articles, however, cannot be downloaded or printed without a subscription or purchase. Nature also permits subscribers of its journals to create links to accessible full-text for sharing purposes. Additionally, Nature will allow journalists to post links to full-text articles. This change is considered a move toward increased open access. For more information, please read an article in the Chronicle of Higher Education and from Nature.
