Content Sharing via rdcu.be sharing links allows unlimited view-only access of shared articles instantly and directly within your web browser. This is provided via ReadCube's exclusive Enhanced PDF streaming technology. The ReadCube interactive article viewer provides features such as annotation tools, dynamic clickable inline citations and author names, figures browser, article metrics and instant supplemental materials (when present).
Due to licensing restrictions, Shared articles do not allow regular PDF file downloads or printing. However, you can save the article and your annotations for offline viewing within any of ReadCube’s free apps by clicking the "Add to Library" button in the top toolbar of the article viewer. Otherwise, articles can be upgraded to full access via a regular PDF purchase.
