When Academia has complete citation data for a paper, we'll show an option to cite that document in our extended paper functions. You can see if we have this option for any particular paper by clicking the three dots next to the "bulk download" button.
For some papers, we'll show the "cite" option. 
This handy button will provide you the full citation information of the document that you're viewing, so you can easily add that data to your bibliography. Simply click the copy icon to save the citation to your clipboard! 
If you find a paper exclusively on Academia that doesn't have that button that you would like to cite, please follow these guidelines!
