**UPDATE**Problem Solved. Please clear the cache & cookies from your browser and try the PDF icon at the article level. It should pop-up into a .pdf document now.
For people off campus accessing PDFs of articles from journals on ScienceDirect, you can access the HTML version no problem through EZproxy, but clicking on the PDF icon brings a pop-up window asking for a log-in.
To get past this problem, you can right-click on the PDF and have it open in a new tab.
We are working to solve this problem.
