The best and most reliable way to create a direct link is to make use of the DOI (Digital Object Identifier) from the publisher’s website. DOI is a de facto standard that cuts across most academic publishers.
However, not all publishers provide a DOI. The DOI is most commonly found near the top or bottom of an article; be sure to check both HTML and PDF versions.
To create a link to any DOI: http://dx.doi.org/PUT_YOUR_DOI_HERE
