Final answer:
In APA style, the heading for the bibliography section should be titled 'References', which should be centered and boldfaced at the top of a new page after the main text.
Step-by-step explanation:
The heading that goes at the top of an APA style bibliography is References. This title should be centered and boldfaced at the top of the new page following the last page of your paper. When creating your References page, each entry should contain the core elements like the author's name, date of publication, title of work, and publication information. This list provides full publication data for each source cited within the text of the paper and should be listed in alphabetical order.
