Mendeley and other reference management tools + tips for finding & managing the correct references!

You want to keep track of all the papers you may ever want to re-read or cite. So you’ll want to use a reference manager. There are lots of helpful ones like Mendeley (a free program I use), Zotero (also free), Endnote (not free), and Pages (not free). These keep track of all the papers, books, etc. you think you might possibly want to cite (or at least remember you read) in the future. They download all the information required for citing a work you tell them to (through a browser plug-in, title search, etc.). And then, later, when you ask them to, they’ll provide references formatted in the style you ask them to.   
 
  
When you’re on an article page you just click on the Mendeley icon in your tool bar and import it. You also have the option to download a PDF of the article (if available) and you can choose to import it into a specific folder in your library if you want to keep things organized by subject, project, class, etc. You can access your library on the web or in the desktop version - and they all sync together (when you ask them to - so if you don’t see something you thought you imported, make sure you’ve synced!).
