When referencing a book in APA style, what information is essential?

In APA style, accurately referencing a book requires specific elements that provide a clear identification of the source. The correct choice emphasizes the importance of including the author's last name, initials, the title of the book in italics, and the publisher's name.

The author's name and initials help attribute the work properly, recognizing the contributions of the individual or individuals who created it. The title, presented in italics, allows readers to identify the specific work among a myriad of publications, while including the publisher's name gives context to the edition and influence of the book. This structure effectively leads readers to locate the source if they wish to explore it further.

While options containing page numbers, ISBN numbers, or details like the digital object identifier (DOI) provide useful information in different contexts, they are not considered essential for a standard book citation in APA style. Page numbers are specifically relevant only in the context of citing specific parts of a work. ISB numbers can be helpful for identifying books but are not required by APA guidelines for referencing. Similarly, the DOI pertains mainly to articles, while books are typically cited through their publisher information. This understanding aligns with APA standards to ensure clear and concise citations, enhancing the reliability and traceability of referenced works.
