How should sources be ordered in the reference list?

Sources in the reference list should be ordered alphabetically by the last name of the first author. This alphabetical arrangement makes it easier for readers to locate the sources cited within the text. When an author has multiple works, those works are further sorted by the year of publication, with the earliest work appearing first. This system of organization is a fundamental aspect of the APA style, ensuring consistency and clarity in referencing. Readers can quickly navigate the reference list for a specific source based on author names, facilitating the verification of claims and enhancing the credibility of the work.
