E-book with no author: different from print version [from Electronic source using APA 6th ed.]


Use when there is no identifiable author or editor, personal or corporate. Do not use Anonymous, unless the book specifically designates the author as Anonymous. The title is placed in the author position in the reference, and italicised. This format can be adapted for other materials where there is no author or editor.

Many electronic sources do not provide page numbers. If paragraph numbers are visible, use them in place of page numbers (using the abbreviation para.), e.g. para. 582. Alternatively, cite the chapter or section, followed by the paragraph number (if appropriate) e.g. Chapter 4, para. 3). 

Whenever possible the URL you give should be a stable URL and link directly to the webpage itself. A stable URL, also known as a 'permalink' will not be generated 'on-the-fly' and is more likely to remain accessible. To check if a link to a URL is stable, paste the link into the address bar of an Internet browser to make sure that it works. The Discovery Service provides a permanent link known as a 'Permalink' for each item in its index, including those in HTML format.  To see the Permalink, click on the title of the item and look under Tools on the right-hand-side of the screen where you will see a Permalink link. Click on this link and the URL will be displayed for you to copy and paste into your reference. Although you must give the full web address (or URL) in your reference list, you do not show this in the body of your essay. Your in-text reference must match the start of the reference as it appears in your reference list. Use the author if your reference has one; otherwise use the first few words of the title.

For books from online collections such as Amazon and iTunes, give the web address of the homepage rather than the full URL of the e-book.
