 This video explains how to include eBooks in your reference list, according to APA Style 6th Edition. For information about in-text citations, check out our other video, Referencing Sources APA Style, A Basic Introduction. In this example, all the punctuation is in red for emphasis. In your actual reference list, all font should be black. Start with the author's last name, followed by their initials. In APA Style, you never write out the full, first, or middle names. Enter the year the book was published, in parentheses, followed by a period. Next, enter the title of the book in italics. In APA Style, the first letter of every word of a book's title is not capitalized. Just the first letter of the first word, the first word of the subtitle, and proper nouns. Next, in parentheses, indicate the book's edition, except if it's a first edition. Use the abbreviation ED. If there is a volume number, enter it here as well, using the abbreviation VOL. For eBooks, you don't need to include publication information. Instead, use the DOI number, or Digital Object Identifier, which can be found in the database where you accessed the eBook. There is no period after the DOI number. Your completed reference will look like this. eBooks will usually have a title page where you can find all of the information you need for your citation. And if you access the eBook through the library, the information will also be available in the eBook database. And here's a hint, you can look an eBook up in the library catalog. All of the information will be listed there as well. Not all eBooks will have a DOI number. In that case, you can include the URL. Make sure it isn't hyperlinked or underlined. It should be in the same font as the rest of the citation. And there's no period after the URL.
