You can use Zotero to create an APA formatted annotated bibliography. Follow these steps:
In the main Zotero pane, choose the "gear" icon and select "Preferences."
Next, in the Preferences menu, choose "Cite" and then "Get Additional Styles."
The link takes you to the Zotero website and a drop-down menu of styles you can add to Zotero. Choose APA 6th edition (annotated bibliography.)
