The ReadCube Web Reader is now available directly from 100+ Wiley Online Library journals and Cochrane Database of Systematic Reviews. So long as you have access to an article (either from a personal subscription, proxy, or through a university login), you can navigate directly to the ReadCube Enhanced PDF from an article page, search page or table of contents page using any of the 'PDF' options. After navigating to the Enhanced PDF within the ReadCube Web Reader, you will notice a ReadCube Toolbar along the bottom screen. Choose the "Download PDF" option to immediately download the article to your computer.
Next to the 'Download PDF' button here is the Add to Library button, which allows you to add an article to your free ReadCube account's library. For more information about adding PDFs from the Web Reader to your ReadCube Library, please see the following article: How can I save articles from the Web Reader to my free ReadCube library?
