Summary
Review of what you've learned
To edit an existing reference, click on the [number] where it appears in the text. You will see either a 
"Reference icon", or the icon (and name) for the template that was used to create this reference. Clicking the "Edit" button opens a "template mini-editor" dialog where you can edit the information for that reference.
Inside the template mini-editor, you change the information in fields by typing in the boxes.
To add a new piece of information (for example, the publication date), select it in the left column.
When you're done editing the reference, click "Apply changes". Remember, you'll still need to then save your changes!
