This method often provides the most robust information about the reference and will sometimes even attach a PDF of the reference to the entry. If a PDF is not automatically downloaded and you have a copy, you can attach it by selecting the reference, clicking the Add Attachment
(paperclip) icon, and selecting the desired attachment type. I tend to use the Attach a Stored Copy of the File
option. Once the reference is added you can access it by clicking on the small arrow to the left of the entry as pictured in Fig. 12. Notes added to the entry can be accessed in the same way.
