1. start with the author's last name
2. use a comma (" , ") and one space between the author's last name and the initial(s) (middle name initial is often omitted)
3. if the author's middle name is hyphenated (Sun-Hee), use a hyphen with a full stop (" . ") after each initial (e.g. Lee, S.-H.)
4. give the year of publication in parentheses and then use a full stop 
5. give the title of the book in italics and then use a full stop; indicate the edition (e.g., 4th ed.) in parentheses, if applicable
7. if the title has two parts, capitalize the first letter in a word after a colon (" : ")
8. use a colon after the location (it can be just a city or city and state)
9. give the name of the publisher (e.g., SAGE Publications), with a full stop
10. capitalize all words in the name of the publisher.

The same rules apply to books with two authors as to those with one author, except that:

1. "&" (ampersand) is used to separate the two authors’ last names
2. a comma (" , ") is used before the ampersand.

The same rules apply to books with three to six authors. However, one should not forget to:  

1. include all authors' last names followed by initials
2. use one space between the authors' first and middle name initials (where applicable)
3. use commas  (" , ") before the last name of each author
4. use a comma and the ampersand (“&”) before the last author's last name.

The same rules apply to books with more than six authors. However, one should not forget to:  

1. if more than six authors are listed, write out the first six authors’ names
2. add a comma (" , ") after the sixth author's name and then an ellipsis (" ... ") to show that the subsequent authors, except the last one, are omitted
3. add the last author's name followed by initial(s) (even if that author happens to be the 20th contributor!).
