APA style requires 2 types of citations: In-text citations in the written part of your plan and an alphabetized bibliography of citations at the end.
Remember: The goal of every in-text citation is to direct your readers back to the bibliography so they can verify the information on their own. They work together.
To ensure consistency, I suggest the free citation manager Zotero (www.zotero.org/). Sources can be managed in group libraries, with PDFs included, and shared among team members.
Pro tip: Zotero doesn’t provide in-text citations unless you download the software and install the add-on in Microsoft Word or Google Drive.
