What components should a reference list entry include?

The correct answer is that a reference list entry should include multiple essential components, which encompass the author's surname and initials in inverted order as well as the journal article DOI if available.

In APA format, a proper reference entry is structured to provide comprehensive and accurate information so that readers can easily locate the source. The author's surname and initials in inverted order are crucial because they help in identifying the author clearly, adhering to the format where the last name is presented first followed by the initials. This not only aids in alphabetizing the entries but also emphasizes the author’s identity in research work.

Including the journal article DOI (Digital Object Identifier) is also significant as it provides a permanent link to the digital content, facilitating direct access to the article. This detail enhances the reliability and traceability of the reference, making it easier for readers and researchers to find the source without ambiguity.

While the answer suggesting just the author's surname would be insufficient, and focusing only on the DOI neglects other vital information, the inclusion of both the author's name formatted correctly and the DOI represents a complete and accurate reference list entry, making all these elements collectively necessary for proper citation.
