Drag and drop the Web Importer into your browser bar and then use it whenever you want to store a document. This means that you don't have to go through the trouble of downloading a copy and then uploading it manually into your digital library.
With just one click of this button, Mendeley automatically imports the document details, citations and any PDF files where available. All of this information is stored directly to your Mendeley library.
This is especially useful for those moments when you need to collect a lot of papers, and quickly. Mendeley Desktop will also back up everything into your online bibliography which you can access and manage from anywhere.
