 When you're writing a paper, correct citations help your readers know where you got the information so they can find the original information themselves. The citation style we're looking at today is the seventh edition of APA. To build correct APA citations, we need some basic information about each source, such as author names, publication dates, and more. For this book in particular, we can use the author's name, the full title, and the name of the publisher to create a citation. Another common source to cite is a website. Siting online sources sometimes involves some detective work because each website provides different levels of information. This page from the Centers for Disease Control and Prevention is a great example because there's no individual author listed for the page. But if we follow APA guidelines, we'll replace the author name with the organization instead, which in this case would be the Centers for Disease Control and Prevention. Next, find the date. In this case, we're given a specific date. However, note that occasionally websites will only provide the month or year. If this is the case, just cite whatever information is available. Next, make sure to include the title in italics in a link to the webpage. Let's move on to academic articles. To cite an academic article, we'll need a few things, such as the title of the journal, the volume and issue of the journal, and the DOI if it's included. A DOI, or digital object identifier, is just a short code that helps readers find the information quicker. A complete citation for an article looks something like this. Notice that the journal title is in italics and the page ranges are included without spaces between the dash and that there's no space between the volume and issue number. Besides more traditional academic sources, anything can be cited in APA from tweets to movies. But since it's unrealistic to have every rule memorized, it's good to know where to find reliable guides to help cite an APA. If you want the original rulebook, you can use the most recent APA publication manual located in the library or check for quick answers on the APA-style website. Another great source is Purdue Owl, which provides great citation help and gives plenty of examples. However, if you're still unsure about anything, feel free to ask a librarian.
