General Information
The Google Scholar plugin takes author and title information from each post or page and outputs it in the document head so that Google Scholar can find it and index it. In order for it to function correctly you must that your authors have a FIRSTNAME and LASTNAME entered into the user profile.
Add a link to the *.ris file using the shortcode [gs-citelink].
