You can usually find all the information you need to cite a book on the title and copyright pages. One major change in the 7th edition is that publisher locations are no longer required. A citation for an eBook is exactly the same as for the print version--simply swap out the name of the publisher for the DOI or the URL to the book. Do not supply a URL, however, if the eBook is from a library database or may be otherwise inaccessible to your reader.
The examples below cover common scenarios for book citations.
Lastname, I. (year). Title of book. Publisher.
Panella, V. (2001). 26-hour day: How to gain at least two hours a day with time control. Career Press.
Cited in text: (Panella, 2001)
For a book with two to 20 authors, list all author names (inverted), connecting the final name with an ampersand (&). For the in-text citation, use the first author's last name followed by et al.

The dictionary example previously given has a group author, and you would follow this format if there is no personal author for the encyclopedia entry. If there is a personal author, the format is similar to a chapter in a book. The example below also shows how to handle a multi-volume work.
