To identify the correct APA citation elements needed for your reference list citation, you first need to know what type of source you have. Looking at a source’s visual clues can help you figure this out.

A source can be in different formats. For example:

• a book can be in print or available online as an ebook
• an article can be in a print journal or available online in a Library database or on a journal webpage
• a video can be on a DVD or streamed online
• and so on…

Other sources exist only electronically, such as blogs or websites and their individual webpages.

It can be a bit confusing figuring out what type of source you have. To help, we will go through some examples of source types and clues to look for.
