A paper is usually divided into chapters and subsections. Each chapter or section has its own heading, and these headings provide structure to a document. As well as many other APA format requirements, there are specific guidelines for formatting headings to ensure that all papers are uniform and easy to read.
The apa running head (i.e. page header) consists of the title of your paper (maximum 50 characters, left-aligned, all capitals) and the page number (right-aligned). On the title page, your paper title is preceded by the words “Running head:”.
A running head is an abbreviated version of your paper’s title. It’s placed in the page header of your document, together with a page number. The running head is only required for professional manuscripts intended for publication, not student papers (unless instructed otherwise).
An APA running head can be up to 50 characters (including spaces) and is written in all capital letters. It’s left-aligned and appears on all pages, including the title page. It’s not necessary to put the label “Running head” in front of the title (as was the case in APA 6).
APA reference entries provide detailed information about a source. They’re listed on the reference page at the end of your paper and correspond to in-text citations in the body text.
You can easily generate APA references (and in-text citations) with a citation generator, but it’s helpful to have a general understanding of the composition of an APA reference. It enables you to review your own work and that of any tool you might be using.
