To import a reference click on the Save to Mendeley button on your brower's tool bar. In the popup box either click on Save all or on the + button(s) next the reference(s) that you want to import. The example below is for a full text database. If a PDF copy of the paper is available an icon appears next to the reference. Leaving the Download PDFs if available box checked will import the PDF's along with the references.
Note! If you select individual references there will be a slight delay after the + button is clicked. When the button turns to a green tick the reference has been imported. If the Save all button is clicked it will change to Saved when the references have been imported.
For databases not supported by the Mendeley Web Importer it is better to use Mendeley Desktop.
Once all required references have been saved the Mendeley popup can be closed by clicking on the cross in the top left hand corner.
