Refworks is a great tool that can help write your bibliography and format your paper for you. See the tutorial below for details.
In order to export, or send, articles to your Refworks account, you must first select the ones you want by checking the boxes next to each one. Then click on "Export citations" above the results list.
Clicking on "Export citations" brings you to a new screen, where you must choose "Refworks Direct Export", then click "Export". You will need to log-in to your Refworks account. For more information on using Refworks, go to the Refworks guide below.
