Important Considerations:
* Italics: The book title is always italicized.
* Capitalization: Capitalize only the first letter of the first word of the title and subtitle, and proper nouns.
* Publisher Location: While traditionally included, the publisher location is often omitted in current APA style.
* DOI or URL: If available, include a DOI (Digital Object Identifier) or a URL. This is especially important for online books.
Example with DOI:
Smith, J. (2023). *The psychology of learning*. Oxford University Press. https://doi.org/xxxxxxxxx
