APA Style
Best resource: The Online Writing Lab (OWL) from Purdue University is a free resource that is full of accurate, helpful, easy-to-use APA help.
The APA Style website is also great!
You can buy an APA handbook as well, but I think most students do just fine with the free resources.
APA Papers
APA papers include a title page, an abstract, the body of the paper, and a reference page. Note that instructors may not require an abstract for very short papers. Other papers, like a business plan, may require additional sections. Always check the assignment guidelines and ask your instructor if clarification is needed.
