Write the name of the corporate entity followed by a period. Make sure that you capitalize correctly, and you can include the abbreviation if you wish in parentheses.

Follow the name of the corporation with the title of the book and another period. The title should be italicized. If your word processor cannot support this type of formatting, then use an underscore sign to indicate that the title should be underlined.

Add the city where the book was published and a colon. This information can usually be found on the inside cover of the book or on the first few pages. If your book was published in Atlanta, Georgia, then your citation should now read: American Association of Retired People (AARP). _How to Age in Your Professional Life_. Atlanta:
Add the name of the publisher followed by a comma. If your book was published by Gerner and Sons, then your citation will now read: American Association of Retired People (AARP). _How to Age in Your Professional Life_. Atlanta: Gerner and Sons,
Finish with the year of publication and a period. If the book was published in 2007, your finished citation will look like this:American Association of Retired People (AARP). _How to Age in Your Professional Life_. Atlanta: Gerner and Sons, 2007.
