The Publication Manual of the American Psychological Association provides many citation examples, but does not cover every resource. Some of the sources you use for business may fall within this area. In these cases, we have to work within the rules provided in the manual to determine how to cite a source.
If we deconstruct a citation into its basic components, there are four elements you need to include when creating citations: who, when, what, and where; basically this translates to: author, date, title, and how/where to locate the item.
These elements are generally formatted in a certain order: Who. (When). What. Where. If you are missing one of these elements, check out this useful table/template from the APA Style Blog: APA Missing Pieces
See below for examples of APA citations for specific business resources.
