We have a whole research guide about APA citation style available for you here!
https://mesacc.libguides.com/APA
And a guide about MLA and APA both here!
Or from the library home page, click on Research Guides on the left menu to browse all our public guides.
One great resource about citing is the Purdue Online Writing Lab, aka OWL.
Another great place to get help with specific citing questions is Ask A Librarian! There are links to that throughout the library web site and this guide, including a box just below this one.
