In SAGE Journals Online and Wiley Online Library, use the link in the URL bar at the top of the page, making sure the proxy URL is added. Science Direct works best when the article title is clicked and the link in the URL bar is used. Again, be sure to add the proxy URL.
Some databases (usually medical or scientific) also offer DOI (digital object identifier) numbers. These may be tried, but we have found they don't always seem to link properly when joined with the proxy URL.
