Consult your list of sources and sort the list items alphabetically by author's last name, since APA style dictates that sources are listed in this order. This will make the bibliography writing process faster and more efficient.
Using the APA style guide to inform your formatting, type the relevant information for each source. APA guidelines vary by source type, but for books, the typical information items required are the authors' names, the book title, the publication date and the publishing company and city.
Repeat the process for each cited resource, adjusting your formatting to the guidelines for journal articles, websites, reports and other kinds of publications.
Ensure that all other aspects of APA style are followed in your bibliography. Check your page margins, header and footer, and line spacing. Give the bibliography page a heading called "References" and center it at the top of the page. Make sure that the web addresses you have included for your online sources are still live pages, so that readers can access your sources if they want to.
Review your bibliography for errors, looking closely for spelling and formatting mistakes. Ensure that you have followed the APA rules for capitalization.
