Q. When citing a website, do you include the retrieval date?
According to the American Psychological Association (2020), "Provide a retrieval date in the source element when citing an unarchived (i.e., not stable) work that is likely or meant to change"...[However], "the majority of references do not include retrieval dates" (p. 290). Most resource types (e.g., journal articles, books, web pages) can be assumed to be in their final forms and therefore references to them do not require retrieval dates.
