You may need to cite a source for which you cannot find a model in APA style. If so, collect as much information as you can find about the creator, title, sponsor, date, and so on, with the goal of helping readers find the source for themselves. Then look at the models in this section to see which one most closely matches the type of source you are using.
In an academic writing project, before citing an electronic source for which you have no model, also be sure to ask your instructor’s advice.
